Wall-mounted high power off-grid photovoltaic controller

Abstract

The invention discloses a wall-mounted high power off-grid photovoltaic controller. The wall-mounted high power off-grid photovoltaic controller comprises a chassis main box body, wherein the interior of the chassis main box body is divided into a control system cavity, a main power cavity and an external wiring cavity; and an internal wiring socket device is arranged on a baffle between the main power cavity and the external wiring cavity, and an external wiring socket device is arranged on a lower part baffle of the external wiring cavity. The wall-mounted high power off-grid photovoltaic controller disclosed by the invention has the advantages that the chassis main box body is divided into the control system cavity, the main power cavity and the external wiring cavity, the three cavities can be isolated from one another, electromagnetic compatibility requirement is met, and the wall-mounted high power off-grid photovoltaic controller has the characteristics of simplicity in mounting and convenience in maintenance; remote and local communication can be realized by arranging a communication unit in the external wiring cavity, and an output port is reserved in the external wiring cavity, so that the demand of different power stations can be met, and the working reliability of the controller is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of controllers, and relates to a wall-mounted high-power off-grid photovoltaic controller.
