Hi there
We have a Victron Quattro 15kVa, and a Freedom Won 15 kWh battery backup system, to a server room with several UPS Systems
There is an automatic generator changeover switch, between mains and generator, that's before the inverter, so the output of the changeover switch feeds the inverter AC supply breaker, which in turn feeds the inverter
The maximum power that the system draws is about 7 kilowatts.
When grid power is lost, the generator takes about a minute to kick in, and the switch over is ok
THE PROBLEM HAPPENS When Grid power is restored, and the generator switches off, then THE INVERTER AC SUPPLY BREAKER TRIPS.
What could be causing this, and how can it be resolved
Regards
Jonathan
