I have a 10kw Enphase microinverter system that I want to retrofit for battery time shifting.
I'm not entirely clear on the terminology (ESS? AC-coupled? Grid-interactive?) but I'm just trying to figure out which inverters that support generic 48V batteries can backfeed power to the main panel/utility grid (safely with anti-islanding protection of course). Whether it's technically legal in California or not I don't care.
My idea is to install a 50 amp NEMA 14-50 outlet in my garage and create a portable battery/inverter rig I can just plug the inverter's AC-In into. I don't want a critical load center and I don't care care about DC PV or outage protection.
I just want to charge batteries during the day and discharge them to the main panel at night. I know the Victron MultiPlus/Quattro can do it, but not necessarily in the US (can it still work without codes?). I think the Sol-Ark 15k, EG4 12/18kpv, and Schneider can do this but those are very expensive.
The SunGold Power TP6048 is cheap and says it can do "Grid Feedback". But the manual on their site for the US version is actually the EU 230V version and gives no information on breaker sizes so I have no clue how much grid feedback it can do.
The EG4 6000XP's manual says "The inverter and system can inter-connect with the utility grid only if the utility provider permits" but I'm 95% sure this unit cannot feed back to the grid, right?
