Solar photovoltaic power generation system is mainly composed of solar panels, solar controllers, maintenance-free lead-acid batteries and AC /DC inverters. The core components are photovoltaic battery pack and controller.
The function of solar controller is to control the working state of the whole system and protect the battery from being overcharged and discharged. In places with large temperature difference, qualified controllers should also have temperature compensation function. Other additional functions, such as light control switch and time control switch, should be optional for the controller.

1. Dust and dirt on the surface of photovoltaic modules are usually removed with a soft cloth to prevent the loss of output power due to the blocking of the module surface. Be sure to check whether the component surface is blocked by objects.
2. When addressing, avoid choosing trees and buildings or places that will block the shadow of solar modules, especially in winter. The installation of photovoltaic modules should be fixed on a permanent frame, which should tend to exert its best performance in winter.
3. When installing and maintaining products, it is necessary to cover the surface of parts with cloth or other opaque materials, because it is very dangerous for parts to generate high voltage in the sun.
