Hey guys i really need some expert advise here
I have got 2 clients
3 x 15Kva Quattros in 3.Phase
1 x 27 Kva Fronius Eco AC coupled
2 x 450/100 Mppts
In South Africa with Loadshedding and line fees
we opted to shift to Utility Prepaid 50 Amp 1 Phase as this is all that is avaliable on prepaid
AS we have had multiple systems before we use 1phase input as backup with 3 phase system we add the 1 phase input on inverter 1 as a Generator and this closes a contactor this works fine if there is not a fronius in the system and only MPPTs but if we try to do the programming with a 3 phase fronius it takes off the PV assistant (my idea was to use the contactor to switch to grid 1 phase but also kick out the fronius for the time to charge the system
I know i can add a additional charger or inverter to do this but its expensive so i need this to work
Any ideas or anyone that has done this please assist
@Guy Stewart (Victron Community Manager) if there is somebody that can help me it is probably you or @mvader (Victron Energy)
Thanx in advance
