    Good small charge controller. Easy to set up.

    This is a good, small charge controller. Easy to set up.Can be configured for Gel, Lead or Lithium batteries. Manual On/Off or automatic operation for 1 to 14 hours per day from the Load terminals.Be sure to connect your battery first, and the solar panel second.-Chris

    Don’t let the size fool you

    This tiny controller is a little beast. I have it in my shed to power my 12v lights and it does the job to keep the 12AH battery charged with my little solar panel. I can always upgrade to a bigger panel and battery later on when I add an inverter.

    Works good however your might want to…..

    Consider a MPPT charge controller as it can take advantage of extra voltage and convert it to current for charging wear as this PWM only can modulate the amount of current to the battery to prevent over charging. NOTE: the wire connection points on this charger are kind of small and take a Very small screw driver to tighten them in. If you move the controller around the wires will come out. You need to mount the controller INDOORS (not rated for outdoor use) where the wires won’t get moved. Works perfect for what it is, there is just better out there. Additional Notes: It looks like if you keep a 5volt item plugged in (cell phone etc.) to the USB port there is not low battery cutoff, at 12.1 volts I just unplugged it to keep from taking the battery down further. All in all this thing works as advertised!

    Buy this instead of the $10ish blue PWM charge controllers

    I have 3 of the low dollar blue PWM controllers rated at 30A and 20A charge current. Only the 20A one reads the voltage correctly, the others are off by as much as 0.5V which is unacceptable for a charge controller. The Renogy is only rated at 10A charge current but the voltage is accurate and the current rating is enough for my 100W panel. Other features not on the others is a backlit display, an internal fuse, a conformally coated PCB to block out the elements, option for wireless communication and ability to read charge current and voltage of the PV panel. These features make it worth the extra 8 bucks or so. I am driving 4ea. 13W LED bulbs for a total of 52W. Each bulb has an incandescent equivalent of 100W, so I have 400W of lighting in my shed.

    Works fine, but don’t expect data from that RS-232 Port

    The good thing is that you can hook this up to a solar panel and a battery and it works right from the start. There’s no real setup – just connect the wires. I haven’t pushed the limits of this thing by any means, but it has been working nicely for days. If this is all you want, please consider this a 5-star review, and carry on.If you want to use this as part of a project which adds capabilities, you may be disappointed. There is an RS-232 port which allegedly supports a protocol called Modbus. There may be a wealth of information available there, but Renogy doesn’t want you to access it, responding “Unfortunately we do not manufacture or know of a cable that will allow connection from the Wanderer port to USB.” No suggestions for an alternate approach or product. Just that statement and a bit of apology.I have been able to find descriptions of successful workarounds with other Renogy products, but they involve some serious hardware and software effort. Don’t expect programmatic access to information such as charging times or currents to be easy. Yes, you can buy a bluetooth gadget and use their app, but all you get is numbers on a screen. If you want to (for example) monitor the state of things with an Arduino or a Raspberry Pi, it could be difficult.To be clear, if this product were just a bit of circuitry with no apparent way to get information, I wouldn’t expect to get it and would not complain. The problem is that the port is there screaming “data is here”, and Renogy apparently doesn’t want you to get it.One oddity should be mentioned; at least it seems odd to me. When the panel is in the dark, the controller still registers a panel voltage close to the battery voltage. My voltmeter agrees. I hoped to be able to detect a distinct drop in voltage under those conditions, but apparently the controller is applying some back voltage to the panel. If you disconnect the panel, a voltage meter shows the expected drop, but as soon as you connect it to the Wanderer, the voltage rises again. It looks like I’m going to have to make all my decisions (such as when there is plenty of power to run an optional pump) based on battery voltage alone.

    Seems to work okay!

    These are manufactured cheaply and you get what you pay for. I wasn’t expecting anything substantial either. It proved to be useful for my project and that’s what it counts. I have used Renogy products before and while they are cheap they are little bit better compared to other Chinese knock offs (Even I am certain this too is made in China) but the quality is slightly more tolerable for the price you pay.This is clearly evident when you open the unit and find that there is no heat-sinks for the Mosfets. But I guess 10A PWM switching does not dissipate that much heat and they have gone away by replacing the back plate with an ALL-Plastic construction while they have redesigned the PCB with more substantial copper and tiny holes for air to circulate allowing the passive cooling of the Mosfets without using any heat-sink whatsoever.Anyways, this is a Pulse width modulated (PWM) based Solar charge controller that is capable for charging Lithium Ion batteries (The main reason for choosing this over others) and I found that you can select “Max” battery charging voltage in the 12vDC and 24vDC ranges and allow further selections in small steps like 12.0, 12.2, 12.4, 12.6 etc for keeping the Lithium battery topped off by using solar panels as your primary source of power.This Renogy Wanderer 10 Amp 12V/24V PWM Negative Ground Solar Charge Controller Regulator can accept wide range of DC voltage inputs (max – 50vDC) and will bulk charge your battery (as much as your solar panel can deliver) and pump all that power in AMPs directly into your battery and as the battery voltage reaches critical value (settable by user for Li-Ion) it starts to reduce the AMPs and slowly and safely reaching the specified value set by the user. Once the battery voltage is reached it will totally stop charging it even if the solar panel is delivering full power on sunny days.PS: Depending on the battery types the float charging and bulk charging algorithms change which is good to know. The manual has the full details on types of batteries that it supports (Including lithium Ion) and good old Flooded Lead Acid 12/24 and GEL type etc.Rating the product with four stars!

    Not easy!

    Instructions seem sufficient. But I had to take the controller off the wall several times to connect the wires. Normally, you install panels and devices on the wall and wire to it. This controller must be connected to wires while lying loose on a table. While the instructions don’t say this, all the connection diagrams show the controller lying on it’s back. The controller was delivered with connection clamps closed. When you look into the connection slots before mounting, they appear to be wide open. But turning the screws on the cover face to tighten when you insert the wires, the clamps cannot close, they will only turn in the open direction. However, the screws do not push the clamps open. Only gravity will do this. So you must open all clamps with the controller on it’s back. But lifting the controller vertical and mounting it can jiggle the clamps closed again. There was no way I could reopen the clamps to receive the wire if they jiggled close. So, I ended up holding the controller in the air horizontally to insert each wire and then turn the screw which pulls the otherwise loose clamp against the wire toward the front of the controller. Whenever, I need to disconnect the panels and/or batteries, I will have to remove the controller from the wall to reconnect the wires.At the very least, Renogy should redesign the termination clamps to work every time while it is mounted in its final position.The clamp screws are small. A flat head screw driver works better than a philips head screw driver. Both can skip out of the screw when trying to tighten. I am not sure you can get enough grip to overtighten.The green PV Indicator light is not much help. Knowing what is a fast flash (over-voltage) or slow flash (charging normally or float) is not easy to discern until you have seen both. When I saw the flashing I opted to be careful and disconnected the panel positive wire. Only to find as I expected that my panel was delivering voltage within the acceptable controller voltage range. But then I had to dismount the controller to reconnect the solar panel wire.I don’t like that charging and float are the same light indicator. I had a much simpler controller where the indicator light was on when charging and off when not charging.This may be a very good controller but its not easy to install nor easy to know if its working correctly without some experience using it.

    For the money this is a great value

    To avoid confusion, this references the Renogy 10 Amp 12V/24V PWM Negative Ground Solar Charge Controller Compact Design w/LCD Display.Renogy seems to be among the leaders in our ever-growing world of solar technology. I have two of the cheap (under $10) PWM controllers, and they work okay, but for the price, I happily upgraded to the Renogy controller. Briefly:Pros:Economical.Will connect to a Renogy BT module (sold separately)Tells me most of what I need to know in its LCD menu.They do have customer service ( but reviews of this are mixed. )Cons: Terminals seem to be designed for wire 12 AWG and smaller. I got 10 AWG in there, but I won’t trust them to stay.A reminder, PWM is not the best type of charge controller, but if your needs are modest and you have no shade to interfere with your solar energy collection, it works pretty well. This 10 amp controller is good for your basic needs, handling up to two, 100-watt panels in parallel (series might be right at the limit). It works with all the major battery types, but you need to manually set Lithium types.If you want or need a more sophisticated solar energy setup for your home or large RV, you will likely want the much more expensive offerings from Renogy, Victron, and others. But for a small camper or backyard project, this is quite adequate. When I’m done playing around with it, I plan to affix it to one of my Renogy 100-watt suitcase solar panels.Need cheap and simple? Buy it.Happy solar, all!

    Yes , really small ! All functions are here and more .But different from other Renogy controller : this one doesn’t show daily charge and discharge!No control over load disconnection, it cut it off at 11 volt .It continuously flipping through display screens and no way to stop it – really annoying !But overall good device, useful !

    Good quality solar charge controller.

    Really good quality solar charge controller. One of the best on the market in that class of chargers among those I could find. Very competitive price. The only problem – documentation. I couldn’t find any information in the manual on how to set up the battery type for the acid battery. So I had to google this. Below is the useful information which might save your time.SLD – Sealed Lead Acid Replacement Batteries. Just a regular car acid battery to start the engine.GEL – Gel batteries are called gel because they use silica. Same as Lead Acid but gel instead of acid.FLD – Flooded Battery: A flooded deep cycle battery is a battery that has thick plates, large separators, and high-density paste material.LI – Lithium. Probably means LiFePo4 batteries type. Also called a deep cycle battery. Has almost the same charge cycle as for acid and gel batteries type. The only difference – you can pick the final voltage on the battery which is nice.

    Works great

    I’m pleased with this device. Works well with the BT-1 Bluetooth device. Renogy app is good. I however, in the Renogy app, I must add BT-1 on every use. It’s easy, just odd. And I couldn’t figure out how to add to my Bluetooth devices on my android phone. But it still works great. Two clicks on my app and all the solar charging and battery data you could wish for is displayed in an easily understandable format. Renogy app is free.

    Bad controller

    This controller did not even last one month. I started to get E01 and E08 error codes after 2 weeks usage on my lead acid batteries. Sometimes I would get an error code as soon as I hooked it up, and sometimes it would give me the error code after a few hours. I get these errors on three different battery banks that I have on my RV. I have installed this on my original solar suitcase (not my Eclipse model), replacing my 5 year old Viewstar controller.I called Renogy and they told me to check the battery voltage and voltage at the controller terminals. I did previously and both were at 12.4 volts, which should be fine. So I guess this controller just does not work for me and I have to purchase another now, and reinstall it to my suitcase. Of course I will use a different model.I actually again checked the voltage after the Renogy tech person seem to really question the voltage at the controller. I disconnected my Battery Tender, and the battery read 13.03 volts after settling down a few minutes, and it registered 12.94 at the controller terminals. So I am pretty sure my connection and wires are ok. By the way, now I am getting more error codes today, EO and EO2, the controller is going crazy with error codes, then it connects and seems to work after a while. Seems to connect and disconnect at random.On a side note, the manual is somewhat vague, on page 14 it says to set the ‘charge voltage’ for a lithium battery (LiFepo4), but makes no mention of what voltage to set it at. There are about 21 different choices with no direction on what they mean or what to use. It goes from 12 volts up to 16 volts in .2 amounts of progression. On page 21, it talks about ‘Boost Voltage’, I have never heard of this, I know the 4 stages of charging a lead acid battery, but what is boost voltage? I guess I need to read up on this.I have had many questions on my reviews for other Renogy products, and I have recently purchased several items; the 100aH LiFePO4 battery, a DC to DC charger (wait till I review the manual on this thing!), several PWM controllers, and several other smaller items. I am also trying to update my current review of the Eclipse suitcase with a major edit concerning the ‘plastic blocks’ that connect the legs to the frame but been have a little technical difficulty with the website.I decided to install another solar controller due to all the problems with this one. I installed the Renogy Voyager 20A Waterproof Solar Controller, and so far it works perfect, no error codes. It also has a better manual and it at least tell me that the ‘charging voltage’ for lithium batteries is set at a default amount of 14.2 volts.Bummer, my first negative review of a Renogy product, but it just did not work well.

    Best charge controller for th price

    I like it so much I purchased another for another project. This is the best charger for the price and amperage. Its not MPPT but almost as good for the price. If you want a good charger that can handle multiple battery types this is it.

    So far so good…

    It has been working for a few days, so far so good. I will post an update after a year if it lasts; I am using it to charge a 35 Ah lead sealed battery as a backup power for an inverter in the event of a power outage or just for any additional power requirement. The manual that came in the box is version 1.1 the online version is 1.0, another thing you need to understand are the charging stages, on the manual there are simple explanations of this important topic. Bulk, Boost (absorption) and float. For flooded batteries there is an option for equalization as well. It works well with my 100 watts solar panel. This is a good charger for anyone starting with solar power, but now I see how important is the feature in some chargers that have temperature compensation charging, this little one doesn’t have it so I monitor my battery temperature during charging from time to time.

    Works as needed – SOLID VALUE!!!

    UPDATE: So after an entire summer of operation, this controller has worked exceptionally well. My single concern of it being in an enclosure that got too hot in the summer sun was eradicated. I never had to turn the little cooling fan that I installed in the box on. As far as I know, it never shut down due to heat. It did, however, save my 12V battery when I left the pump on all night. It cut the power after it got to somewhere around 10-11 volts (the limit is in the manual) and resumed operation when the solar panel charged it to the proper threshold. Great value in this tiny controller.After reading others’ reviews, I don’t know what some people expect from this unit. It is ridiculously cheap and works exactly as advertised. I have it connected to a 12v battery running a DIY solar water setup for my stock tank pool, and it is EXCELLENT! It works just as well as another solar controller I have for a larger setup, but is exceptionally small. It is perfect for my needs, as I have it installed in a clear faced junction box. My only concern is the temperature rating, which the spec states is up to 130 degrees F…if I remember correctly. During summer, this may be an issue. I tried to keep it in the shade and installed a small fan to assist in cooling on hot, sunny days. Time will tell if it has any issues in the middle of summer, but that is a chance I was willing to take with such a good, cheap unit. Either way I would definitely recommend this controller for smaller projects…(10 amp limit of course).

    Overcharges the battery. Voltage exceeds setpoint.

    I bought two of these to use with 50 watt solar panels and charge 12V LFP batteries.Intially everything looked good and I liked the features. I set up both units and began charging, monitoring progress along the way. These units are PMW, which is less efficient than MPPT, but they seems like a good value and I didn’t need maximum eff.Charge eff. was around 80%, better than expected. However when I checked on it near the end of charge, the battery display was reading 0 volts. Odd. As I watched it, the battery voltage jumped to 13.5 volts, then 17, then 18 volts and back to 0. Charge controller was set to Li battery, 12V nominal, and 14.4 volts max charge, but the system kept climbing to 18 volts before the battery’s BMS disconnected to protect the battery. When it reconnected, the charger climbed back to 18V.This is a very dangerous flaw that could have caused a large fire if the battery had not disconnected itself.I even tried lowering the max charge voltage on the chance the battery disconnected prematurely, but it made no difference. This was a dangerous charge controller.

    Good

    I’ve only used it a few days,but it’s working like a champ. I had 2 100 watt h.f. panels feeding a h.f. controller, during peak hours it would shut down from too many amps leaving a partially charged battery. Now I’m using both in parallel to charge 3 flooded deep cycle 109 ah batteries keeping everything fully charged. Both are fairly equal in operation but I think this brand will prove better, you will need to use external meters to see power usage,production. But the price is still worth it I’m sure to be looking at this brand for more.

    Has trouble with non resistive load

    Two complaints. one is that the display is hard to read at a glance. it cycles through 6 different measurements, like PV voltage,PV current, battery V, etc. It should just have one display that shows PV power and battery voltage at the same time.Second complaint is that if you have a non resistive load like a DC-DC switching power supply, the device shuts down with an error immediately. If you hot connect your load after this device has been turned on for a few seconds, then it is ok. I worked with tech support, but they agreed that it was a limitation of the device and there is nothing to do except switch the load on after the device output is turned on.Once I got used to this, the device did function and it recharged my LiOn battery several times while out in the desert, using a 12A flexible PV panel.

    Simple and easy to add solar to my RV.

    I have a 100 watt portable solar panel to charge my two RV batteries and this Renogy controller works excellent. So simple to install and gives me the current voltage in my dual batteries. I have a quick connect to plug in my solar panel and it begins charging automatically. When the batteries get down to around 12.4 volts from overnight use I plug my solar panel in and set it in the sun and my batteries are back up to full capacity in around 3 hours of sunlight and ready for another day and night of boondocking.

    This unit is small.! Have eyeglass screwdrivers handy to loosen/tighten attachment screws..

    I had a Renogy Rover 40 amp controller that developed a glitch (couldn’t “see” my battery). After a bunch of work trying to find the problem I just ordered this little 10 amp unit (one 100 amp solar panel feeding my coach battery) figuring that if it didn’t work the problem wasn’t the controller. I hooked this baby up and yay! all seems good. Readout fed me info on solar panels, battery and load. The only difficult with install was that the size of the connection holes are so tiny that I had to search for a toy size screwdriver to get wires attached. Renogy offers plenty of technical data online. Renogy had also provided online help about the 40 amp controller but I was going to be more time into the back and forth of information so just buying this little unit saved me time.

    Great Charge Controller

    This charge controller does the job efficiently, and reliably! The instructions a basic, but clear enough… connect the battery first, THEN connect your power source. It works every time. Here’s my application: I do a lot of camping- boondocking- with a pop-up trailer. My trailer has 12-volt batteries to run lighting, etc., and I have a generator, so I can fire up the A/C, when it’s really hot. On generator power, the converter onboard the trailer will recharge the battery bank (2 batteries)… but very slowly. My generator also has a dedicated, 8-amp output for charging 12-volt batteries… but, it’s unregulated. So, I electrically “isolate” one of the batteries, connect it to this charge controller, and connect the charge controller to the 12-output of my generator. Works amazing! My RV’s converter charges one battery, this charge controller handles the other, and they both charge quickly- without overcharging. For the price, this charge controller is a superb value. I’d recommend it, without hesitation, if it’s specifications fit your needs. And I’d buy it again, if I had need for another. This unit has been rock-solid!

    Have not needed tech support

    This thing is pretty amazing. There’s a video review of this item but the user is doing everything wrong and he thinks it’s the devices problem. First off, hold the grey button LONGER than 7seconds to change between battery types, push it quickly to rotate through or cycle the battery options and they are all color coded for ease of locating. The video of the user pushing the grey button for less than 5 seconds is really bad and misleading. He did NOT read the instructions. Hook up t he battery first and hold the grey button for longer than 7 seconds to set battery type. Then connect the solar panels. Know this: the set screws arrive in the clamped shut position and you MUST unscrew them to open the connecting terminals (again the guy with the bad video states the screws are bad) using a small driver designed for smaller screws. Do NOT use a number one screw driver, it’s to big and will cause head stripping. The only draw back is there is no USB connection and that would be nice.

    It’s okay

    It does what it does. Paired it with goal zero 100w. Easy to connect wires use it camping and house. Battery connected to 100 ah lithium from bass pro. You need to buy the Bluetooth adapter to get readings. I didn’t get the thermal reader that also sold separately. I would buy another item from temu that has more features and accessories and price wise.

    Good cheap solar controller

    Used this for a set of 3 100 watt panels ran in parallel. Very cheap price. I did not want to spend the money for a MPPT unit. Set up as a portable panel set that I set outside the RV when dry camping. Use the generator to bulk charge the batteries for an hour or two and then top the batteries off with the solar panels. The controller is mounted inside the RV so does not need to be waterproof

    Reliable name, and quick, easy install

    I use a Do-It-Yourself small solar system to daily power a freezer in our hot Texas garage. I seemingly runs most of the day in the summer time. I’ve added a 3rd 100w solar panel and had to upgrade to a 30A solar charge controller to charge my battery string, as a result. I chose Renogy because of the ‘reliable’ name brand. I have a 1000W Renogy inverter that I have run for over a year with no issues. The install of this new Renogy Wanderer was very straight forward, easy, and quick. My only complaint was ‘self-inflicted’ 🙁 I’m use to having a digital meter on the front of the controller, telling me the charging current/voltage/watts being used, etc. Being a DIY’er and tinkerer… I enjoy seeing what it’s doing! I, for some reason, got involved in the reviews and didn’t even notice there wasn’t one!! It just has colored LED’s to report the systems status. For the normal person that’s a non-issue. It’s a good unit! 🙂

    Top notch quality!

    I ordered this to replace the junk controller that came with my TOPSOLAR 170 watt panel kit. The controller that came with the kit dies after 3-4 months. I connected this controller and it has been working great. I have also noticed that I am getting more power from the panel to my RV battery. I wasn’t able to compliment on the tech support or weatherproof since I didn’t need any tech help and I have this controller installed in a weatherproof enclosure on my camper. Renogy is apparently the way to go!

    Won’t fully charge my flooded batteries

    Works well, I like that it will handle a bigger voltage input than most the controllers this size. Only problem is it shows the battery voltage almost a full volt higher than they actually are. Which means my batteries are not fully charging.Probably going back and try with a new one. Hopefully it’s just a fluke.I have the Adventurer in my camper, it has been rock solid for years, but it did cost three times the amount of this one.

    Great little Solar Controller

    I wanted a decent but cheap controller for a battery minder. This is top quality with an excellent manual. In English. With pictures.I can’t understate this advantage over the cheap Chinese generic ones.This controller simply works. And, it’s TINY! The screen is easily read in sunlight. Well worth it.

    No customer support

    I have purchased 6 of these and when one of them didn’t work Renogy was not willing to replace it. I have spent thousands on Renogy products and they are very good quality products but if something is wrong they don’t stand by their product. Even when it’s only a $38.00 charge controller.

    Good, inexpensive controller

    Best thing is the reasonable price for just a simple controller. This does everything you need for a basic solar application. Tech support from Renogy, on the phone or email, has been among the best I have encountered.

    Maintains correct voltage

    I had an inexpensive solar panel with an internal voltage regulator set up to maintain my boat batteries, however the regulator went bad and began overcharging. I was able to cut out the old regular and splice into this separate voltage regulator and now the batteries are kept at safe levels. It has held up for a year in a marine environment so far. We will see how long it lasts.

    Good For What It’s Supposed To Do

    This unit is inside a box on the back of my electric pontoon. It controls the charge for one Lithium battery for my console. It was nice that the terminals can handle the thick gauge wire used from solar panels. It would be nice if the blue tooth option was built in. Haven’t purchased that piece (yet). I had a similar unit from the same manufacturer that only lasted 6 months, but it wasn’t of this quality. I have high hopes once again.

    Power mismatch

    Good controller, however it was ordered with two 100 watt panels as a package. This controller is only rated a 130 watts at 12volts. So to use it you have to go to 24 volts.

    Works well for a low price point.

    Function: I used this to charge a large 12v battery (900CCA), with a 50w panel. It took awhile to charge it to full from 8v. Cloudy days, inconsistent sun, etc. Separately, I used it to charge a 10AH 12v battery and it worked well.Durability: It seems fairly durable, as it’s been dropped a few times, and it’s gotten wet from rain.I would not recommend using 10 (awg) gauge wire, as it struggles to stay connected. I’m using 14 awg to the battery and it’s fine. 12 would probably be fine.This was my first iintroduction to solar. Next time, I’ll buy a higher wattage panel and charge controller. Overall, it works well.My only complaint is it continously cycles through the display settings. I would’ve liked to leave it on one display only. But, low cost, ease of use, and durability takes the win more 5 stars.
