My system is up and running very glad thanks Victron.

I do have one problem will come to that now first my setup.

4x MPPT250/100 each with 16 330w solar panels

3x 48/15000-200-100/100 inverters in 3 phase configuration

1x 1040ah by 48v deep cell battery bank(bit on small side but working on that)

1x CCGX connected to everything

ESS loaded on all inverters firmware upgrades done on all configured for 3 phase L1/L2/L3/N/PE

Now when my ac grid returns the inverters don't want to stop inverting and switch the grid thru.It is stuck in inverter mode.

Any ideas please.

if you monitor the inverters (devices, multi) what do you read on input/output/etc?


Did you measure on the inputs?

What firmware are you running?

Have you checked phase rotation? If the phase rotation is incorrect it will not accept grid. A simple way to check is to swop phase 2 and 3 on the inverter input side and see if they accept. Also look at the grid code setting and ensure that the supply is within those parameters

And thwe winner iiiis Murraynated. Phase rotation. Like we say in south Africa give the man a Bells (whiskey)

Thanks
