This type of power station can be divided into an independent power generation system with batteries and a grid-connected power generation system without batteries. Solar power generation is divided into solar thermal power generation and photovoltaic power generation. Photovoltaic power station automation equipment includes photovoltaic cell arrays, combiner boxes, low-voltage DC cabinets, inverters, AC low-voltage cabinets, etc. Photovoltaic inverters are inverters that can convert the variable DC voltage generated by photovoltaic (PV) solar panels into AC power at the mains frequency, which can be fed back to the commercial power transmission system or used by off-grid power grids. Photovoltaic inverters are one of the important balance of systems (BOS) in photovoltaic array systems and can be used with general AC-powered equipment. When building photovoltaic power station automation equipment, it is necessary to install a monitoring and operation system to monitor the photovoltaic power station automation equipment.
