Collection: String Inverters

These convert the DC power from photovoltaic (PV) panels directly into AC power to be fed into the grid. Called 'string' inverters as the PV panels are wired together in a series string to obtain the required DC input voltage. Storage batteries are not used, as any power produced that is not consumed by the owner’s electrical loads is fed into the grid to be used elsewhere.
