Photovoltaic grid-connected cabinet is a distribution equipment connecting photovoltaic power station and power grid, and is the total outgoing of photovoltaic power station in the photovoltaic power generation system, and its main role is to act as the dividing point between the photovoltaic power generation system and the power grid.
Grid connected PV systems always have a connection to the public electricity grid via a suitable inverter because a photovoltaic panel or array (multiple PV panels) only deliver DC power. As well as the solar panels, the additional components that make up a grid connected PV system compared to a stand alone PV system are:
The advantage of a Grid Connected PV System, either with or without storage batteries is that on clear blue sunny days, when the photovoltaic system is producing large amounts of current and the home is consuming low energy levels, for example, if you are out of your home all the day working, you’re solar system keeps generating electricity.
Inverter – The inverter is the most important part of any grid connected system. The inverter extracts as much DC (direct current) electricity as possible from the PV array and converts it into clean mains AC (alternating current) electricity at the right voltage and frequency for feeding into the grid or for supplying domestic loads.
