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.

Review from a similar PWM in Solar Charge Controllers


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.


Comments
One year update... all is well! The GP-PWM-30 is still performing as designed. No issues.

Review from a similar PWM in Solar Charge Controllers


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!

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.

Upgraded to this Go Power controller to be better accommodate the charging of our newly installed lithium batteries. Easy install and works great. Now I know the Li batteries are being properly charged. The old control worked ok using the AGM setting, but this one is designed for lithium and I like the Bluetooth feature. Just remember to “Disconnect” when you are done using the app.

Review from a similar PWM in Solar Charge Controllers


I replaced an older Go Power PWM Solar Charge Controller that came with the RV in 2016 with this one so I could have Bluetooth control and be able the more fully monitor the state-of-charge of my 200 AH Li-ion battery bank. The swap out was very straight-forward. Make sure to disconnect the battery bank before transferring the wires. The unit powered up as expected upon reconnecting the battery. Setting the Controller to monitor Li-ion battery was easy per instructions that come with unit. Paring Bluetooth with my phone and a the unit was the most challenging aspect but was accomplished after moving around in the phone app. All in all a great experience so far. Should issues arise I will update as appropriate.

The controller works as advertised. The hardest part was cutting through the paneling, I did not need the template on the last page as it matched the one on the wall, but I was glad it was there. Very good instructions. Down loaded the app and pushed a few buttons and the Bluetooth connection was made.
