BIS differentiates between two types of PV inverters for CRS purposes: Power Inverters for use in Photovoltaic Power Systems (which includes off-grid/standalone inverters) registered under IS 16221 (Part 2):2015 alone, and Utility-Interconnected Photovoltaic Inverters .

A On-Grid inverter, also known as a grid-interactive or grid-connected inverter, is a device that converts the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity, which is compatible with the utility grid.

Traditional microinverters operate as grid-following devices–they require an active grid connection to function and synchronize their output to match grid frequency.

Either the hybrid or the asynchronous inverter will allow you to connect directly to the grid (alongside an ATS and associated electrical components). As you get set up, choose components that'll allow you to prioritize where your system gets its energy.
