I have a client who has purchased a battery system and Victron Quattro 3kW 120V inverter which they need to AC couple to their Enphase microinverter based PV system which is 240V.
The issue is the best way to achieve the 240V to AC couple with the Enphase during an outage.
Has anyone had experience with using an autoformer on the 120V output of the Quattro to transform to 120/240V needed?
Or is there a better solution in this instance?
Sunny and healthy regards
