I have 2 x Multiplus 5000w and a heat pump that draws 3kw max and a new EV charging station that draws 3kw too. My garage DB is connected to the main house db on a 10mm 70amp cable and on a 50amp breaker. I can upgrade the 50 to a 63 amp but wondered what was the best way if at all to run the circuits gone that on full load it could draw 75+ amps?
More info required, such as a schematic drawing to determine where loads are in relationship to supply /inverters / grid tied or off grid ect ect.
I’ve actually spoken to my electrician this morning and he recons that it’s possible if the EV charging station / GX device can back off loads due to cumulative load levels being exceeded.
