Hi all,
a friend has an older off-grid solution with inverter 24/5000 and lot of lead batteries.
Now he wants to upgrade with Multiplus2, BYD Box Pro 13.8, AC-coupled Fronius and CCGX.
The question is, can he use the older inverter like a generator only for emergency power ?
And will the CCGX be able to communicate with the inverter ?
to illustrate the idea.......
