Two Phase ESS setup with 2 x 48/8000/110 Quattros, 15kVA three phase generator with Titan 48/50 Charger on third phase.
Firmware: CCGX 2.53~2, Quattos 469.
Generator on AC-IN-1 with current limit of 14 Amps. All good while loads are low and system in Bulk, charging battery. Current hovers around 12 - 14 Amps. The problem I have is when a large load turns on, the mode changes to "Pass Thru" and excessive current is drawn continuously from the generator. I was monitoring the system when the 3kW water heater came on. I watched the Quattro draw 27 Amps from the generator for 30 seconds before I turned the generator isolator off. This is virtually twice the limit set.
Dynamic Current Limiter - disabled
UPS Function - Enabled
Was going to try the "Dynamic Current Limiter" but the increase in current is not temporary. It matches the loads applied and completely ignores the “AC Input Current Limit”. Also I don’t want it working while connected to the grid.
Please advise if I’ve overlooked something.
