This system is perfect for a small cabin.
3,000W of solar panels, a 10kWh battery and a 3000VA inverter.
AC Distribution box with a GFCI and 20A circuit breaker is enough to power your loads.
For winter we have a generator which recharges the battery in one day.
UPDATE: The price of 150/35 MPPT has come down, in my video i show to use inline MC-4 fuses and a Y-combiners. I have now updated the diagram to include two MPPT’s.
