I have a few AC/DC clamp meters, one has a peak function with a with a slow decay, tried a big power saw, 140A surge, no problems. Threw a 2kw jug at it @ 41A while it boiled, 1.4kW vacuum cleaner. All just plugged into the AC out, no Variac.
No smoke yet.
Going to add a quick charge start, in case I turn the Battery switch on before precharging, I'll also a Load disconnect whilst powering up, I know these are already on wiseguys boards, but I need something independent of the inverter while testing.
Because I use an ATA with the current inverter, load disconnect/connect, battery low and over voltage etc are all handled independently of the inverter anyway.
Test setup on a small part of the main battery bank rewired to 48V @ 9kW.
FYI: The existing HF inverter [24V -> 400VDC -> 230 AC], it's powering everything at the moment including the house and work shed, here is the mains waveform from one of the AC outlets.
