Description
ESP8266 based MPPT Solar Charge Controller Very low quiescent power, multi-chemistry batteries. Scalable power drivers.
N.B. The schematics are different flavors of the same project.
The automatic generated BOM is not valid!
Use only the first schematic, the other ones are not maintained!
Don't know how to hide them.
