The photovoltaic off-grid power generation system is mainly composed of photovoltaic components, brackets, controllers, inverters, batteries and power distribution systems.

　　When installing the photovoltaic off-grid power generation system project, the following matters need to be paid attention to:

　　1. The installation azimuth and inclination angle of the battery panel array need to be considered.

　　2. Avoid blocking between the battery boards. Including surrounding buildings (telephone poles, eaves corners, etc.).

　　3. The stability and firmness of the bracket placement (considering local meteorological data, such as sunshine time, severe weather, storms, etc.).

　　4. The circuit traces in the layout should be as short as possible and average.

　　5. Related accessories must meet the system requirements (such as wiring posts, wire diameters, etc.).

　　6. The wiring terminal should be firm to prevent virtual connection or open circuit.

　　7. Pay attention to the polarity when installing the battery, and the terminal should be firm (do not short-circuit).

　　8. The controller generally has corresponding power distribution protection measures. During the wiring process, attention should be paid to prevent reverse polarity, short circuit, rainwater immersion, etc.

　　9. For systems with inverters, the inverter must be connected to the positive and negative poles of the battery, not the output of the controller. In addition, necessary power distribution protection needs to be loaded to ensure the safety of the system.

　　10. The place where the system is built must be open, and no tall buildings or other things can block the sun at the place where the solar cell array is installed.

　　11. During the installation process, pay attention to electrical switch protection, etc., to prevent live operation, so as to cause unnecessary losses and troubles.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect replacement for lead-acid batteries, and they are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.
