Abstract
The utility model provides a reverse-current resistant and zero-power-consumption adjuster to solve the problem of reverse currents in electricity output circuits of prior solar batteries or solar battery packs, and relates to the technical field of photovoltaic systems. The adjuster comprises a solar battery and an electricity output circuit connected with the solar battery. A driver bi-directionally connected with a controller is connected in series on the electricity output circuit, a signal input end of the controller is connected onto the electricity output circuit through an acquisition circuit, and a signal output end of the controller is connected with an isolation disconnecting link controlling the connection and disconnection of the electricity output circuit. The reverse-current resistant and zero-power-consumption adjuster is reasonable in design, applicable to a photovoltaic system and capable of blocking reverse currents generated in a prior solar battery electricity output circuit rapidly. Compared with the prior art, the controller is connected onto the electricity output circuit, the current direction of the electricity output circuit can be monitored in real time, and reverse currents can be blocked through the driver timely, accordingly, the energy consumption brought by reverse currents is prevented, and remote control can further be achieved.
