Most of the Hybrid inverter solutions are higher-powered, more expensive and more complex because see they are designed to supply backup power during a grid outage.
I’m looking for the best UL-Approved budget All-in-one or All-in-few solution with a battery to minimize import and export only. Backup power is not a priority at all and can either be impossible (grid-tied functionality only) or can be very limited (120V only, non-automatic, modest output levels).
I’ve seen the Growatt solution of single-phase hybrid + Autotransformer is currently getting a great deal of interest, but the cost and complexity of an Autotransformer is only needed because of backup power capability which is not worth that hassle (and possible safety concerns ) to me.
Are there any split-phase solutions based on high-frequency inverters which are UL listed?
My ideal system would be 24V or 48V battery-based split-phase AC limited to 1.5-2.0kW per phase (meaning 3.0-4.0kW max) with DC-coupled MPPT and either CT sensors for grid and AC-coupled solar or energy meter control/interface.
The Solark Hybrids are close to perfect but much too expensive for my budget (and positioned for higher power output levels).
Are there any otherUL-listed Growatt-like solutions in terms of price point that deliver full Solark-like capability at the more modest power levels (and lower battery voltages) that I am seeking?
