Is a hybrid inverter any good?

Heard a random thought about a split phase hybrid inverter similar to the eg4 pv18k. Integrated with your own battery of choice, grid tie, solar pV, and a dedicated breaker panel and optimized settings like preventing it from back feeding into the grid does some magic. Anyone else wondering if this works?

Setting the inverter in a position wherein you can prioritze solar and off-peak grid power? And since you're not grid back feeding you woudn't need a go signal from your utility, though I guess building permits would still be required. Thoughts?
 
Yeah, hybrid inverters like the EG4 PV18K are solid, especially for setups where you wanna control power flow without dealing with utility headaches. Actually, the whole "non-backfeeding" setup you're talking about is known as zero export mode. It's been around for a while but not every inverter handles it well. The EG4's split-phase design makes it pretty flexible too, good for balancing 120V and 240V loads without needing a transformer.
One thing though — even without backfeeding, some areas still require utility approval just because you're connecting hardware that can affect grid stability. Permits? Yeah, probably still a must. Just be sure your breaker panel setup matches the inverter's load management options or you'll end up with power gaps during transitions.
