So I have to buy their smart panel and ask an electrician to do a smart switch with my solar panels when there is power outage? Is that correct?


edit: I already have 8.8kW solar panels system.

Eco flow sells transfer switch as well. You could install that one (or any other transfer switch like reliance or other brand) and re-route like 12 circuits from your home main panel to this. Transfer switch would give you ability to physically separate from grid and be in off grid mode for selected circuits. if your existing panels are on house they need to support rapid shutdown device. If you used to have solaredge optimizers or micro inverters you might need to remove those and install generic rapid shutdown modules for each panels and have rapid shutdown button installed as well.

Yeah, got the panels from Tesla back in 2022. I believe micro inverters.

The price is lowered so with the 5% code it comes out very close to the original with 10% off.
