Things to note when solar energy storage power supply is not used for a long time.

August 29, 2024

If the solar energy storage power supply system is not used for a long time, the following points should be noted:

1. Keep the charging state: In the case of long-term non-use, in order to keep the energy storage Battery charged, it can be charged regularly. It is recommended to charge it every once in a while, and the time interval should not exceed 3 months.

2. Turn off the load: In the case of long-term non-use, all load devices need to be turned off to prevent battery power loss.

3. Prevent overcharging or over-discharging: In the case of long-term non-use, it is necessary to prevent overcharging or over-discharging of the energy storage battery, which can be achieved by connecting to the BMS management system.

4. Moisture and dustproof: In the case of long-term non-use, the energy storage battery needs to be placed in a dry and ventilated place to avoid moisture or dust.

5. Regular inspection: Energy storage batteries that are not used for a long time need to be checked regularly to ensure the normal operation of the battery. It is recommended to conduct a comprehensive inspection of the battery once a year, including inspections of battery capacity, voltage, internal resistance, etc.

If the solar energy storage power supply system is not used for a long time, the following matters need to be noted:

1. Keep charging: Long-term non-use will cause the battery power to drop and affect the battery life, so it is necessary to charge it regularly to keep the battery power within the normal range. If the solar energy storage power supply system is not used for a long time, it is recommended to charge and discharge it at least once a month. This helps to maintain the health of the battery and extend the battery life. When charging, it is best to use an appropriate charger and charging current to avoid damage to the battery. When discharging, try to avoid over-discharging the battery to avoid affecting the battery life. In addition, when storing the battery, avoid high and low temperature environments, and keep the battery dry, ventilated and away from light.

2. Maintain the battery: It is necessary to check the battery status regularly, including voltage, temperature and capacity, and maintain or replace the battery in time if problems are found.

3. Operation before power failure: Before power failure, the power of the Solar Energy Storage System needs to be turned off and the battery power is placed within a safe range.

4. Prevent environmental damage: The solar energy storage system needs to be placed in a ventilated, dry, moisture-proof, waterproof, and dust-proof place, and away from dangerous environments such as high temperature, high pressure, and fire sources.

5. Regular maintenance: It is necessary to regularly check and maintain various parts of the solar energy storage system, including solar panels, inverters, batteries, lines, etc.

6. Instructions for use: Before not using it for a long time, you need to understand the instructions for use of the solar energy storage system and master the operation methods to avoid system damage caused by misoperation.
