GCSOARSolar Charge Controller 40A 12V 24V Auto PWM Solar Panel Charger Regulator Parameters Adjustable LCD Display for Leaded Gel(AGM) Flooded Type (40A, 12V/24V)

This is a decent little PVM it works well with my solar panels and keeps my battery bank full. I appreciate that it is basic enough to not need an owners manual, but sophisticated enough to handle all of the power requirements and switching back and forth from power to battery. This feeds my battery, then the battery feeds a 2000W power inverter that powers practically my whole house. This came faster than stated, so shipping was fast and it arrived in brand new condition as I expected. Thank you GCSOAR!

This is my first charge controler, i have been using it since December 2020, it was easy to install, the instructions was 75% clear for the programming, i like the size of the unit, the terminals are large which is really good for large wire sizes.the display is not my favorite, as it jumps (toggle) through the parameters but i will put up with it, so far it is doing what i expect it to do.i am pleased with its performance thus far. will update in the coming months

Controls did not work as advertised. Tried to figure what was wrong and finally realized that there was a poor connection somewhere inside the unit that constantly changed values on the LCD. Extremely poor quality control. Back it went.

We got this when we were getting our second solar panel because the controller the first one came with had no information at all. This one tells us the temperature of the batteries, the charge of the batteries, how much the solar panels are charging, and how much the batteries are being used. It's very helpful.

We love the easy read our on the screen. Has worked well for us. No complaints.

It seems to be working fine. The instructions are horrendous‼️ My husband who has an extensive electrical background could not make any sense if the instructions.

So far I really dig it's quality and the fact that it doesn't have a horrible blue screen like a lot of them do. Sleek and compact, yet can handle my 600watt system..awesome. edit: Not clear on how to select battery type, if even possible.

Works good however a bit hard to understand the install directions. Had to YouTube for assistance
