Solar inverters may be classified into four broad types: 1., used in where the inverter draws its DC energy from batteries charged by photovoltaic arrays. Many stand-alone inverters also incorporate integral to replenish the battery from an AC source when available. Normally these do not interface in any wa.

How do inverters provide grid services?
In order to provide grid services, inverters need to have sources of power that they can control. This could be either generation, such as a solar panel that is currently producing electricity, or storage, like a battery system that can be used to provide power that was previously stored.
What inverter do I need for a hybrid solar system?
Be sure to confirm inverter compatibility if you're installing a hybrid solar system tied to the grid that also uses a battery bank. The two most common inverters are string inverters and microinverters. String inverters install easily and connect several panels together, but one panel's failure affects the whole circuit.
How do grid-following inverters work?
Traditional “grid-following” inverters require an outside signal from the electrical grid to determine when the switching will occur in order to produce a sine wave that can be injected into the power grid. In these systems, the power from the grid provides a signal that the inverter tries to match.
How does a string inverter work?
String inverters connect a set of panels—a string—to one inverter. That inverter converts the power produced by the entire string to AC. Although cost-effective, this setup results in reduced power production on the string if any individual panel experiences issues, such as shading.
