What is a grid tie string inverter?
A grid tie string inverter, also called a “centralized” inverter, is the most common type. It is usually installed next to the utility meter or main breaker panel and converts the DC electricity from all of the solar panels into AC electricity. The main advantage of string inverters is that they are cheaper than micro inverters.
