Solar Basics: Hybrid inverters can future-proof solar+storage installations

Inverters are the electronic heartbeat of a solar system, connecting solar arrays to the grid and increasingly, to battery storage. As utilities continue to shift rate structures in ways that often harm grid-tied residential solar customers, inverter manufacturers are working to make battery integration seamless.

Solutions described as “battery-based” or “hybrid” inverters are becoming more common across the manufacturing sector. But what do these terms actually mean?

Sol-Ark manufactures both inverters and batteries and calls its solution a “battery-based inverter.”

Tom Brennan, engineering manager at Sol-Ark, said that most inverters in home installations are grid-tied string inverters. They don’t work with batteries, but instead have to sell all the power they produce back to the grid.
