I’ve heard about three types of DC to AC converters used in the solar power business.
Microinverters, String inverters, Grid-Scale Inverters
Please how they work.
In: Technology
A control circuit generates a stable 60Hz signal. That signal is used to control power transistors that switch the DC from the batteries/panels and make an AC signal. The AC is then filtered, and used to power devices designed for wall power. It’s not synchronized with the local power grid, most of the time, requiring switchgear to disconnect your house from the grid to connect it to the solar system. Some solar inverters are grid synced, when the grid power is available, though regaining sync when the grid comes back sometimes requires a switching glitch.
