A power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC). The inverter is a component of each renewable generating project evaluated for interconnection requests. Receipt of an Approval to Install notification in the interconnection application process is validation the inverter specifications were reviewed and accepted.
Institute of Electrical and Electronics Engineers (IEEE) Standard 1547 provides the criteria and requirements for interconnecting small generator equipment to the grid. Underwriters Laboratory (UL) Standard 1741 sets the requirements for the inverters and charge controllers used in photovoltaic (PV) systems.
