MPPT Solar Charge Controller, 40A/50A/100A 12V-24V Auto Focus Tracking - Solar Panel Regulator Charge Controller withThunder Protection and Perfect SOC Function (100A, Blue)

junk that melted

They explain in the instructions that it's not regular MPPT and some functions expected are not present. That aside, this is not a bad charge controller for lead acid batteries and serves its purpose for a small price tag.

I am upgrading my solar system and this fits the bill. However, I can’t use this in a second system to be installed in another building because I will use lithium batteries there and this controller is not for such batteries.

As described... can't really review until I use the device

Very easy to install . Works well

wanted to buy one, but couldn't find what the maximum input voltage was, and, couldn't find where to get the information. Very disappointed in lack of important informations.
