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.


Automatic Multistage Charging System

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.


Charging Modes

  1. Bulk: This mode charges at the full rated load for a quicker recharge time. As the name suggests, this is where the bulk of the charging happens. It typically charges the battery to at least 80% capacity.
  2. Absorption: This mode provides controlled voltage to ensure a full charge. Once the battery reaches between 80% to 90% capacity, the absorption state will kick in and start charging at a regulated voltage. In each charging profile, this mode is set to last for 30 minutes after the bulk charge is completed.
  3. Float: Once the battery reaches full charge, this mode maintains a lower voltage to compensate for self-discharge. This reduces battery stress and minimizes gassing and water loss.
  4. Equalization: On flooded/wet cell batteries, this mode activates to prevent stratification and sulfate buildup during extended float cycles. These two issues can damage a battery by causing the accumulation of acid at the bottom of the battery and hardened sulfate crystals on the battery plates. This mode is especially helpful when your battery is going unused during storage.

Practical, Convenient Features

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.


How It Installs

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.

This was a replacement controller I installed to allow the solar panels to work with lithium batteries. It works great.

Still working fine.

Ideal for DIY retirees with too much time on their weathered hands. Our RV was prewired. All we had to do was install the controller and solar panel. Ni more utility bills surge as long as the weather plays nice. We highly recommend GoPowr for solar charging on a budget.



by:

No news is good news. It is functioning as would be expected. The only difference is that I had to change the mounting from horizontal to vertical to accommodate the mounting brackets, other than that it works great

My “charger” is still working great

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!

I contacted the manufacturer and it looks like you may have received and older model. The up to date models, like the ones in stock now, do in fact have the capacity to charge lithium batteries like the product descriptions says. I will have our customer service team reach out to you about this to make sure you are taken care of.

I 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.

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.



by:

Excellent choice for a single 100w panel mounted on a vehicle. Space is at a premium so this being about the size of a deck of cards and being completely sealed makes it possible to mount in the engine bay. Price is right and I can verify it does exactly what I’d expected keeping 2 Odyssey batteries topped off while running a fridge/lights/charging devices in my 99 Tacoma.

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!



by:

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



by:

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.



by:

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.

  • Will A 30 Amp Solar Charge Controller Charge Batteries Faster Than A 10 Amp Solar Charge Controller
    Hi Donald, Yes, a higher amperage charger, like the # GP76QR (30 amp), would be able to provide a faster recharge for your battery bank than a 10 amp controller like the # 34280503. When adding in the second battery you'll want to wire it in parallel with first battery and the charge controller can be still be wired to the first battery. Adding in a higher amperage controller doesn't mean that you'll automatically get more amperage though. You're still limited to the output of the panels...
