Inverter power breaker trips.
I have an 8KW inverter, 8KW solar array and a 5.2 KW battery. If I'm using 3 or 4 KW domestic load all is fine - unless the sunshines more strongly quite quickly, such as cloud passing by. Then the 16A power supply breaker will sometimes trip. The second 6A breaker is OK as is the main 63A one . 3 or 4 times a week typically, only during daylight.
is this normal?

Having contacted the installer, yes, the electrician assumes it was a 3.6kw inverter...
They will replace it with an appropriate version later this week.
Thanks to all for the help, appreciated.
