Our generator connection boxes protect PV systems on the DC side from surges that can damage the inverter and the system. Additionally, a fuse disconnect switch with a 20A 1000V fuse is integrated. This device serves for the safe disconnection and short-circuit protection of the system. The connections for the inputs and outputs are made easily via spring-loaded or screw terminals. The spring-loaded terminals are also equipped with a disconnection knife and a testing option.
Cable glands are provided for the cable entries. The fully insulated plastic housing with a hinged viewing window has a protection rating of IP65. The generator connection box is pre-wired and tested according to standards.
