I hope the next step for this is plug-in battery storage. All the on-grid battery hybrid inverters I can find in the USA are either single leg 120V or 12kW for $5k. I just want like 3kW dual-leg with support for a dozen kWh of batteries
The Bluetti Apex 300 is an expandable 2.7kWh 3.8kW dual-leg battery + inverter + solar generator for ~$1000 (on sale).
The EG4 12kPV does 8kw split phase output and is $3k, but haven't seen anything smaller than that yet.
Yeah it seems like the inverter manufacturers don't see demand for that. I was thinking maybe the Victron Multiplus-II 2x120 could be paired for 240V output but I was wrong, that's only on grid power, it won't make 240V from battery.
Obviously the inverters and pairing technology exist, but I don't know where to buy one retail.
