Note #1: Grid support inverters are inverters that include advanced functionality and communication abilities and are commonly known as “smart inverters”. The Grid Support Inverter List includes information for solar and battery inverters. It's a device that converts direct current (DC) electricity, which is what a solar panel generates, to alternating current (AC) electricity, which the electrical grid uses. The Solar Equipment Lists program has updated Request Forms for the following equipment types: Use of the legacy PCS request form for. The existence of photovoltaic (PV) product listing procedures (UL1703 for PV modules, UL1741 for inverters) has gone a long way in providing consumers and building and electrical inspectors with the necessary assurance regarding safety and installation requirements.
