VICTRON MPPT and GX Device for 200KWP Array

Hi Everyone


We have a client that wants to go off grid. He would however need a 200KWP array to generate the required amount of total yield daily... That leaves us with a bit of a problem as the new Maxi GX will give us 25 Mppts but that still only means maximum array of 148KWP using 250/100A Smartsolars...


Any ideas or suggestions? had been thinking going AC coupled Hybrid but seems like a waste as his KVA requirement on the inverter side is only 60KVA, so going 180KVA to accommodate PV inverters for the array seems like a waste...

Any advise would be appreciated...


Kind regards

Nice project! :-)
Why don't you do a mix?
Do the 148 kWp on the DC side with the 25 * 250/100 Smartsolars.
And then do the 60 kVA with AC solar inverters on the AC side. (3 times 20 kW Fronius Eco inverter, for example)
I assume you have 60 kVA of Victron battery inverters? (4 times 15 kVA Quattro?)
Would that work?
Best of luck and post a few pictures when it's done! :-)
