Portable solar photovoltaic system as independent power source

Portable solar photovoltaic system
as independent power source

 

Portable solar photovoltaic system is intended for energy supply of the household and special DC electric equipment of capacity up to 60 W. It is made on the basis of solar photovoltaic modules (MF). The system consists of: the solar module, pressurised storage battery (AB) with a charge controller and a signal device about a mode of system operation (they are mounted in the separate block), a network charging device (adapter) and a compact luminescent lamp.
