Typically for large-scale photovoltaic off-grid power systems, the specially designed high power photovoltaic intelligent controllers, multi-channel input array of PV modules, convergence to one output. For the battery charge and discharge management, according to the battery pack voltage changes, it automatically controlling components and modules connect or disconnect to maximize the use of solar energy, and also avoids battery overcharge or over discharge problem. In addition, through the power controller multi-input, multi-chip components can be simply connected the controller to solve the traditional large-scale systems require multiple small controllers, complex parallel wiring, to avoid errors caused by lining issues. According to off-grid photovoltaic power system and the different battery design, solar controller are divided into 24V, 48V, 96V, 120V, 192V and 240V and other specifications to meet different users' needs or program designer
