Solar Power / Panel Inverter – Grid-Intertie Inverter using Attiny45

Leave a Comment / AVR ATmega Projects, Battery Projects /

For the last year I’ve been working on a prototype for a Solar Inverter that can be Grid Intertied. A solar inverter takes the 12V DC (or other voltages) from the solar panels and converts it to 120V AC which is the power that most of your household appliances use. A Grid-Intertied inverter allows you
