I am trying to understand why you would like to go DC DC
I have a 10 kw solar and 3 rigs working on 220v in an Island configuration without being attached to the grid
If I compare the production of the solar hybrid inverter system (with 27 Kwh lithium batteryDC/DC) with what has been used by the rigs the loss of the inverter is 5 % max.
the 5 % is worth the effort ?
27 Kwh battery sounds massive. Does that run the rigs 24/7? I agree, a 5% win would not be worth the effort. Thanks! - This is what I've been looking for. Btw, that's only the loss on the inverter (DC to AC). The S9 power supply (AC to DC) has a small fan on it. How much additional loss do you get on the power supplies? I'll presume it's additional 5% loss. Panels are cheap so provisioning extra power for that would not affect CapEx. Do you think eliminating the inverter and power supply would significantly reduce CapEx?
