Distributed photovoltaic solutions

Application

Nowadays, grid companies usually require photovoltaic grid-connected systems to be irreversible , that is, the electricity generated by photovoltaic grid-connected systems is consumed by local loads, and excess electricity is not allowed to supply to the grid. The system can regulate power generation in order to prevent the photovoltaic grid-connected system from generating reverse power.

Centralized PV solutions

Application

In the solar PV power generation system, the smart PV combiner box reduces the connection between the solar PV cell array and the inverter. The box can monitor the operating status of the solar panels, lightning protector and DC circuit breaker. With RS485 interface, the device can upload the measured and collected data and equipment status.
