Done my instelation myself. Need some pointers and help with VE configuring of the Quad inverters for 3 phase. Have 3 phase grid supply want to run my setup as a backup if the grid fails.
Any help would be thankful

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.

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
