Abstract

The invention discloses a junction box for connection power source units, comprising a first connecting terminal and a second connecting terminal, a first signal connecting terminal and a second signal connecting terminal and a switch module. The first connecting terminal and the second connecting terminal are used for transmitting the direct current supplied by the power source units. The first connecting terminal and the second connecting terminal are used for transmitting control signals. The switch module controls the electric coupling relationship between the first connecting terminal and the second connecting terminal according to the control signals. The invention also discloses a power system using the junction box and a method of controlling the power system.

Description

technical field [0001] The invention relates to a junction box and a method thereof, in particular to a junction box for a power supply unit, a power system with the junction box and a control method thereof. Background technique [0002] Solar energy is a safe and non-polluting renewable energy with considerable development potential. The integration of solar cells with building materials or glass is more in line with the current trend of energy conservation. For example, solar photovoltaic panels can replace roofing materials, be used in building exterior walls, or building glass, etc. However, because the voltage generated by a single solar photovoltaic panel is very small, it is usually necessary to connect multiple solar photovoltaic panels in series through a junction box (Junction Box) to form a larger voltage supply. [0003] The traditional junction box is a small box containing several Schottky diodes and two external cables with positive and negative terminals, w...
