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.

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

working like a champ!

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.

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

Still working fine.

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.

Works great no problems at all.

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.

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:

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

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:

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.



by:

No complaints works as advertised. Good product. Installed in my 27 FB airstream.



by:

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.



by:

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.



by:

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.



by:

This product replaces the original solar controller that didn't have a lithium battery charging profile. All I had to do was switch 4 wires. The new controller has the same dimensions as the old, so no modifications were necessary.

  • Do I Need a Solar Panel Controller for My Solar Pre-Wired Camper
    If your 2022 Coleman 17B is already setup for solar then it may already have a solar controller so you wouldn't need an additional one. It doesn't hurt to double check though so definitely look at your setup and see if you have the controller.
