This is an interesting question, what is the fault level at the inverter when it switches over to battery backup, if you have one, 2 or 10 batteries connected.
How do you work out the fault level when carrying out the inspection report for the COC?
Lets say a you are using 5.2 kwh (48 VDC) batteries, in parallel.
I am interested to see some of the calculations done by electricians who issue COC for solar installations.
