SUAOKI 20A Solar Charger Controller 12V/24V PWM Solar Panel Regulator Auto Parameter Adjustable with LCD Display and Dual USB Port

This is a solid unit that has performed well for me. I'm new to developing solar systems for off grid purposes, but this was a simple to set up and use solar charge controller. I am only using a couple of 100 watt panels set up in series, so the 20 amp rating is more than enough. It's a good unit at a good price.

I bought one and sent it back. The seller replaced it at no charge, but i had the same issue with the second one. The unit was registering my voltage at double what i had hooked up to it. As a result, it did not charge properly. The seller took both units back and refunded, so they were good about it.

I previouly used controllers without the display panel. It's nice to see what state your charging system is in.

You can't beat it for the price. It preformed as advertised. My only issue is keeping the wires connected to the controller.

Works but not sturdy

Good.price for a basic solar charger

Holds together nicely and easy to assemble besides the screws head size being rather small and easy strippable. All together a decent product for the price.
