[QUOTE="binky, post: 502980, member: 490"] that's a big load for a MH. Normally MH run a few lights and a small TV, relying on mains hook ups or driving to charge up the batteries fully, the PV being used to reduce battery drain rather than full power supply. 600w for 24 hours = 14.4 kWh without any energy losses converting from DC to AC. Battery at 48V P=IV so that's 600/ 48 = 12.5A 12.5A for 24 hours = 300Amps. So you would need a minimum of 300A battery to run 600w for 24 hours. (at 12v that would be 1200Amps or 10 large batteries, so go higher voltage) In reality you will need more than that to allow for system losses and poor weather when the sun doesn't shine much. To get 14 kWh from a set of panels you would need at least 2kW of panels for about 2/3 rds of the year based on good pitch towards the sun etc etc. Now if you forget the crypto mining and severely reduce the load on the batteries you could well enjoy a bit of gaming for a few hours a day, but don''t forget other loads like fridge and lights.
