In the solar energy storage system, the selection of inverter and battery is very important, they are the core of the whole solar energy system.
The matching principle of inverter and battery is: the voltage and capacity of the battery should match the inverter. In the solar power generation system, the function of the inverter is to convert the DC power generated by the solar panel into AC power to meet the power demand of the home or industry. The battery is a device to store the power generated by the solar panel. Therefore, the matching relationship between the solar inverter and the battery determines the operating efficiency and stability of the solar power generation system.
When selecting a battery, it is necessary to determine the capacity and voltage of the battery according to the power of the inverter. First, confirm the output voltage of the inverter, which is generally 12V, 12V or 48V. After confirmation, the voltage of the battery must also be the corresponding volts. Finally, confirm the capacity of the required battery according to the total power that the inverter can provide. For example, if the power and voltage of the inverter are 5500W 48V, then the required battery is a 48V 150Ah battery, or three 24V 100Ah batteries in parallel.
