String Inverters

String inverters are the most commonly used type of inverter. Under this PV setup, the solar panels are wired together through a common “string” and all of the energy the panels produce is sent to a single inverter that is typically located a short distance away in a location between the solar array and the switchboard.

String-based systems are easy to maintain and are currently cheaper than systems using microinverters. 

The main disadvantage of a PV system tied to a string inverter is that is only as good as the worst performing panel.
