10-Amp solar controller with PWM technology regulates solar panel output to provide consistent amperage to your RV batteries. Protects battery from harmful overcharging and uses automatic multistage charging to extend battery life.
Features:
Specs:
This solar controller prevents harmful overcharging by adjusting the power generated by a solar panel before it reaches your RV batteries. It uses pulse width modulation technology to regulate the output through pulses that provide a consistent charge. Typically, this type of technology is a good fit for smaller systems with lower voltages.
Using a multistage charging system, the controller automatically switches voltages while the battery bank charges. This accelerates the charge, but also helps extend battery life by adjusting the voltage during the different modes. The controller is compatible with multiple battery types and includes preset charging profiles for sealed/gel, AGM, flooded/wet cell, and lithium batteries.
The backlit, digital display acts as an information center for your solar panel output. It shows the charging current, battery voltage, and battery state of charge. It also allows you to input your battery type and choose a charging profile. Additionally, a built-in USB port on the front of the controller provides a convenient outlet to charge your cell phone or tablet.
Lastly, the controller includes several built-in safety features to help protect your equipment. The charging process will shut down if the controller starts to overheat and when an overcurrent is detected. Also, if the battery or solar panel is wired incorrectly, it activates a reverse polarity alarm.
The solar controller flush-mounts to a wall inside your RV. It is wired to the solar panel using MC4 cables. Then, the battery bank is wired to the terminals on the controller. You can also install a fuse or circuit breaker (sold separately) up to 10 amps between the solar controller and battery for additional current protection.

10-Amp solar controller with PWM technology regulates solar panel output to provide consistent amperage to your RV batteries. Protects battery from harmful overcharging and uses automatic multistage charging to extend battery life.I am disappointed! Contra to the detailed product information that is advertised on your website for this controller, the solar controller unit I received, DOES NOT handle / charge lithium batteries! Like I explained to CS prior to submitting my order, the description of the controller on the website, does not match the actual item being sent and please check it before shipping! So, buyer beware, if you want a controller that will charge lithium batteries DO NOT order/purchase this item from etrailer!
Brooke M - 12/05/2022I am not sure about the solar charge controller as I will not use it for some time. Pual B was outstanding to help with the wheel. I realized that I ordered the wrong wheel but then called right back and he helped get the right wheel and get the order out. It was good to be able to talk to someone and your service was very good.
Works great no problems at all.
Great product, nice update to my old Go Power.
Every time I call with an order Karen is amazing! She is the friendliest and most helpful associate I've dealt with.
Review from a similar PWM in Solar Charge Controllers
This is an upgrade to the original Go-Power Solar Controller that came with my Lance TT. It will easily handle the increased production from the additions of a portable solar generator. The small increase in the backside dimensions forced me to slightly increase the opening to allow it to fit. The screw holes aligned perfectly. Before buying a replacement for your unit that has a malfunctioning display screen, you might try to disconnect the battery then return the power... it might reset for you.

This dual bank controller is what every RV needs. It charges the camper first as primary, then charges the chassis starting battery secondary. Never a dead starting battery since. RV sits all winter to full charged batteries in the Spring.

Brought this as a upgrade to my original GP-PWM-30 which did not specifically support a Lithium battery profile. Also for the remote Bluetooth Android App. Looked around for a MPPT solar controller that supported Dual Battery Banks without finding a suitable one. So I want back to this GoPower brand of PWM controller that did. It has performed as expected and the upgrades made seem to have increased the amount of AmpHours drawn from my solar panels by a small amount. I still wish it had been fully upgraded to a MPPT controller.

It installed just fine with my set up. After the latest software release, I found it did everything as advertised including the aforementioned Bluetooth connectivity issue in other posts. I had no problems and look forward to camping in my trailer next year with the controller in my rig.
Review from a similar PWM in Solar Charge Controllers
The switch from the non lithium controller to this one was easy. But the controller reads 100% all the time which confused me. I did call Go Power and spoke to someone about that and his reply was that it would always read that. And the best thing would be a battery monitor. Yet another thing to change out or add.

These controllers work great. But etrailer is the hero offering them at better prices & way better customer service than [online options]. etrailer actually answers there phone & have people there who know the products. I'll buy from etrailer from mow on.
Review from a similar PWM in Solar Charge Controllers
This unit replaced the one in my Lance 855S that did not have bluetooth and it has been working great. Based on the odd mounting place that Lance used, this unit is very handy with the bluetooth and pairing it with my phone to show the information that I like to see occasionally such as amps coming in, state of charge, etc. etrailer was very quick with shipping the unit and I would certainly consider them for a future purchase.

If you lose the Bluetooth connection you may have to disconnect the wiring. Bluetooth is very sketchy. Go out of its short range without disconnecting and you may have to disconnect the wiring.
Review from a similar PWM in Solar Charge Controllers
Was quite pleased with this controller and the solar panel that I got through etrailer. This controller has a much more detailed power display than the one it replaced. It was easy to install and was able to hook up 2 solar panels making my dry camping, which makes up about 95% of what I do, much better knowing that my batteries are fully charged.

etrailer.com is our go-to source for our trailer and motorhome parts and upgrades. We've always been more tha pleased with not only their service and prices but also the quality of the website including the product descriptions and expecially the helpful videos. This most recent purchase, a GoPower Solar Charger is awesome! This is a direct replacement for our failing Speciality Concepts Mark PV Controller. This unit fit perfectly into the existing opening and the mounting screws lined up. This GoPower controller charges the battery bank considerably faster and far more efficiently. Our battery voltage memains higher and the "boost" feature quickly tops off the battery during higher useage. As an added bonus, this is able to charge a secondary battery bank which we use to charge and maintain the engine batteries in our motorhome. Finally, it's easy to use and can handle many battery types including Lithium. What a great value!

I have always received excellent service and fair pricing from etrailer. Go Power is an excellent product.

I like your tracking software. The order was delayed because of poor weather conditions in Kansas City but still came to me on the expected date. All was in good condition. I replace the old controller with this updated one and it was a simple install and the whole system works great now. Thanks
Review from a similar PWM in Solar Charge Controllers
Works well. Is very much seamless in its operation . Ocassionally the Bluetooth interface to my iPhone would need to be re established but it seems app updates may have eliminated that issue. With 300 watts of panel it is able to bring two batteries up from 50% charge to full charge in a day and a half during summer. Fit my lance 1172 pickup camper perfectly. Panel knockout and wiring were already in place from factory.
Review from a similar PWM in Solar Charge Controllers
I needed an upgraded solar controller to be able to charge my LiFePO4 batteries. I also did not want to have to cut another hole in the camper wall, but be able to use the same spot without modification. The installation was a perfect replacement.
