Go Power RV Solar Panels - 34276119 Review

Today, we're going to take a look at the Go Power 12 volt PWM solar charge controller with the USB port and the LCD digital display. This is a 30 amp solar controller. Uses PWM technology, which monitors and adjust the output from your solar panels to prevent a harmful overcharging of your batteries. This is compatible with 12 volt solar systems up to 488 watts. Does use the digital PWM technology that stands for pulse width modulated. This will regulate your panel output through pulses to provide a consistent charge.

The automatic multistage charging it switches the modes that the battery charges. It helps extend the battery life. It offers preset charging profiles for sealed/gel, AGM, flooded, and lithium batteries. And the bulk mode charges at the full rated load for a quicker recharge time. Has an absorption mode, which provides control voltage to ensure a full charge and a float mode, which maintains a lower voltage to compensate for self discharged, which reduces your battery stress.And then the last is the equalization mode, which activates to prevent stratification and sulfate build up for flooded batteries during extended float cycles.

This does use maximum power boost technology. Allows you to top off your battery charge to run electrical loads at night. Activates the bulk mode manually during any charging stage. It does offer the dual bank battery charging terminals right over here. This will let you charge two batteries.

Has a nice back-lit digital LCD display to monitor your current voltage and state of charge, and it offers a Bluetooth function. So it lets you monitor your statistics and configure your settings from your smartphone using the free Go Power connect app. The USB port right here in the front. If I take the plug out, you can see. This will provide an outlet to charge any small electronic devices.

Now the solar controller can be used as on and off remote for Go Power pure sine wave inverters with a communication cable, which would connect right down here. Now those items are sold separately on our website.This does have built in safety features to protect your RV's electrical system. Has current protection for your battery reverse polarity, solar array reverse polarity, overheating, short-circuiting and excess current. It is a flush mountable designed for a nice sleek integrated look. Just want to give you the cutout dimensions. In other words, the portion that will be the rough opening or the cutout that this will fit into. So measure from here to here for the width. If we go across you can see it's right at 5-5/8 inches long. The cutout height, it's going to be right at 3-1/4 inches tall. And the cutout depth, to be from the back, it's about 1-3/16 of an inch. Now a complete controller dimension, the whole overall dimension on this, if we measure it edge to edge, is 7-1/2 inches wide, 4-1/4 inches tall and the total depth, including the face plate, about 1-1/4 inches deep.Few specs on this again, the application is 12 volt battery and solar systems. Does work with the sealed/gel, the AGM and the flooded lead acid and lithium iron phosphate batteries. Maximum solar rate current is 30 amps. Voltage for the battery range is 6 to 15.5 Volts. Maximum solar panel input voltage 28 volts. And the last thing, operating temperature range for this it's -40 degrees Fahrenheit up to 140 degrees Fahrenheit. And if you notice, we laid out on the table, it comes with a nice user's manual that describes how this operates and then the four mounting screws for installation. But that should do it for the review on the Go Power 12 volt PWM solar charge controller with the USB port and the LCD digital display.

I have an existing 30A GoPower PWM charge controller and a three panel array of GoPower solar panels (approx 480W). I am considering adding two more solar panels and another PWM charge controller. Do you have a video or written instructions showing how to wire the two PWM charge controllers in parallel?

@DanF there is not a video specific this your build, but this sounds pretty straight forward. Both PDMs connect to the coach battery directly as shown in your product instructions. You might even consider routing power from all pannels to a 60 amp MPPT controller like the Go Power # GP54FR



do u have a video showing how to use once installed?

If you skip to the 6:15 minute mark on the attached video you can see where we run through the functions of the controller.
