A solar inverter is used to convert the Direct Current (DC) electricity generated by solar panels into a usable form of Alternating Current (AC) that can be used to supply the grid or run AC loads/appliances. Three types of solar inverters available are: micro inverters, string inverters, and central inverters. Micro inverters are typically attached directly to individual photovoltaic modules. String inverters are designed to be wired to a string of 8-15 solar modules connected in series. Central inverters are a type of string inverter used in large scale applications. Some say they offer easier installation and higher efficiency than smaller string inverters, but at slightly higher installation cost.
