ac coupling Fronius pv inverter sizing with Victron inverter/charger.

hi all,

can i connect 3x 5kw multi inverter/charger couple with 3x15kw fronius grid tied inverter?.during the day the power consumption is 57amps on each phase,but in the night the power consumption just only 10amps on each phase.

so to minimise cost of the batteries i will need to install 3x 15kw pv inverter to handle huge load during the day.is it posible to connect with 3x5kw multi inverter /charger?

Only on AC-In, the PV inverters are far too big to go on AC-Out. See 1:1 rule.
