This Low Dropout Voltage (LDO) solar charge controller uses a simple differential amplifier and series P channel MOSFET linear regulator –their compatibility seems like a marriage made in heaven.

This is a simple solar boost converter and voltage limiter circuit that charges a 12V battery from a 6V solar panel. It also demonstrates MPPT (Maximum Power Point Tracking) capability. When we think ...

I think my “MPPT” controller is mistakenly sensing my full 12V AGM as a discharged 24V battery and over-voltage charging it - has anyone seen this happen and know a solution? I bought a new Kings 160W ...
