go power solar controller

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

With Maximum Power Boost Technology, you can simply press a button to activate Bulk mode for the highest charging voltage. This lets you quickly top off your battery bank before the end of the day by capturing as much power as possible.

solar controller terminals

This solar controller is built to charge two battery banks and has terminals for a primary and secondary battery. Your primary battery will receive the full current until it is completely charged. Then, your secondary battery will start to draw the charge current.

solar controller digital display

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.

It includes a Bluetooth function that lets you connect the controller to your smartphone or tablet with the free Go Power! Connect app. With this app, you can wirelessly view the same live battery information included on the display. Also, you can control your battery profile and toggle Maximum Power Boost Technology mode.

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.

Power Control for Compatible Go Power 12V Pure Sine Wave Inverters

By linking the solar controller and a Go Power 12V pure sine wave inverter with a typical telephone cable, you can control the inverter's power function. Additionally, when the battery bank falls below 11V, the controller uses an automatic low voltage disconnect that shuts down the inverter. After the bank has been sufficiently charged (12.8V for lead acid and 12.2V for lithium), the inverter will turn back on automatically.

Compatible Pure Sine Wave Inverters

  • GP-ISW700-12
  • GP-ISW1000-12
  • GP-SW1000-12
  • GP-HS1500-12
  • GP-ISW1500-12
  • GP-ISW2000-12
  • GP-SW3000-12

How It Installs

The solar controller flush-mounts to a wall inside your RV. The manual includes a mounting template with measurements to ensure proper installation. It is wired to the solar panel using MC4 cables. Then, the battery bank is wired to the primary terminals on the controller. If you are using additional batteries, they can be connected to the secondary terminals. You can also install a fuse or circuit breaker (sold separately) up to 50 amps between the solar controller and battery for additional current protection.

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. 900260

Very fast delevery and very good tracking. Thanks 894805

On the web site it was easy to find the solar charge controller that I needed. It arrived in a few days, it was easy to install, and is a significant improvement over the controller I replaced (an older version of the same controller). Very happy with the product and the service 883450

This is exactly what I wanted and it arrived when they said it would. eTrailer had the lowest price I could find on line. 880352

Excellent service and delivery ahead of time. 868140

- 34276119

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. 818571

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. 783115

Since I am switching to lithium batteries, I needed a new controller and this is the one I wanted. It is available from all the traditional sources, but etrailer had the best price and quick, free delivery. The online store is seamless and easy to use, the process was fast and everything came as expected. 762922
