The [http://www.youtub...] is a preliminary circuit idea to match a low voltage solar or wind turbine input to a higher voltage battery. An analogue circuit will measure incoming current and voltage inputs to set the maximum power point tracking (MPPT) and boost the output voltage up to charge a higher, or equal voltage, battery. Input voltage range: 9v through 60v. Output battery voltages: 9v through 60v. MPPT will work only if the battery is higher than the input source. Otherwise, the circuit will act like a direct connection, source to output.

I have some documentation videos. It is 9v through 60v MPPT boost to a 48v nominal lead-acid battery.

It needs more testing after I attach a wind turbine and a monitoring microcontroller.

Otherwise, it seems to work, so far. How much power can it handle? I am not sure yet. I think 500 watts minimum and maybe 1K to 4K watts.

Fridge Defrost Timer with Solar Trigger Option

The project video shows a fridge timer which can be set to trigger during high battery voltage sunny days so the defrost cycle never uses valuable battery power. It is switchable to act like a regular defrost timer for long cloudy stretches of time, like winter.

Solar panel rotator motor power with auto-shut-off

The project video shows a way to power solar panel rotator motors from a solar panel, supplemented by a walladapter.

MPPT Solar and Wind Power Boost Charge Controller

THIS IS NOT READY. IT IS JUST HERE AS MY BACKUP COPY WHILE I DEVELOP THE IDEA.

I have some documentation videos. It is 9v through 60v MPPT boost to a 48v nominal lead-acid battery. It needs more testing after I attach a wind turbine and a monitoring microcontroller. Otherwise, it seems to work, so far. How much power can it handle? I am not sure yet. I think 500 watts minimum and maybe 1K to 4K watts.
