the 3200-watt 24-volt inverter: calculates out to needing 156.25 Amp fuse so a 160 Amp fuse should be about right.

3200 watts divided by 25.6 volts equals 125 amps

125 amps times 1.25 fuse size increase factor equals 156.25 Amps

the 15000-watt inverter is 48-volt.

so 15000 watts divided by 53.2 volts equals 281.95 Amps

281.95 Amps times 1.25 fuse size factor increase equals 352.44 Amps

I have 355 amp and 400 amp

**NH** fuses... so either of those should work for the 15000-watt 48-volt inverter...

still trying to understand the fuse jargon better to get the right fuse for the different parts of the system...

DC-rated disconnects are still to be determined for better quality/ reliability.... still working on that part...separate from the fuse part.

the sun was out in good force yesterday (January 27th,2024)and production was good for PV with a little snow melting at 36 degrees Fahrenheit...

with improving outside temperatures >>> I was working on the support shelf for the larger LiFePO4 in the off-grid solar power shed....a heat wave compared to 20-30 degrees below zero Fahrenheit with wind chill a week before!!!
