① If the portable outdoor energy storage power supply is not used for a long period of time, it needs to be fully charged and then placed in a dry and dark environment;
② The portable outdoor energy storage power supply should be discharged every month or so during the storage process, and it should be charged for about 10 to 15 hours after each discharge to ensure that the power supply battery is fully activated;
③ Before restarting the portable outdoor energy storage power supply, let the UPS power supply use the charging circuit in the machine to charge for 12 hours before connecting to the load. For the backup power supply, keep the portable outdoor energy storage power supply in inverter every month. The state of the device works for 2 to 3 minutes to activate the battery.
④ Attention should be paid to the environmental location of the portable outdoor energy storage power supply. The location should be kept away from water, flammable gases and corrosive items, and must have good ventilation.
⑤ When using a portable outdoor solar power supply, first calculate the size of its load, and try to avoid the power supply load being too large or too small. Excessive load will make the portable UPS work in an overloaded state for a long time, which will seriously shorten the service life of the portable mobile outdoor energy storage power supply.
⑥ Frequent startup and shutdown should be avoided as much as possible. Frequent opening and closing operations may cause the portable outdoor energy storage power supply to fail to start. The correct operation is: after disconnecting the power supply, wait at least 6 seconds before restarting.
In order to avoid the capacity reduction of portable lithium ion power station, Ryangi reminds users to do the following:
1. Before the portable outdoor energy storage power supply is not used, its safe storage power should be kept at 60-70%.
2. When the lithium battery of the portable power supply is not used for a long time, it should be charged at least once within three months. In this way, the capacity of the portable outdoor power supply will not be reduced, and it is also of great help to prolong the service life of the portable mobile outdoor energy storage power supply.
3. The portable outdoor power supply should be placed in an environment with good temperature and humidity and a relatively dry room temperature. Otherwise, excessive humidity or high or low temperature will affect its normal use. Generally, the suitable temperature for storage is -10℃-40℃ °C.
Summary: The above are the correct maintenance skills and methods for outdoor energy storage power supplies. Portable power station should not be idle for a long time. UPS using ordinary batteries, the battery life is about 2 years, and the battery or electrolyte must be replaced when it expires; the UPS with built-in maintenance-free lithium battery will generally fail after 6 to 8 years, so try to use it if it can still be used. Leave your portable emergency power idle.
