At low temperatures, the activity of the lithium battery decreases, which can easily lead to rapid and high power consumption of the battery. Therefore, attention should be paid to the use of batteries in winter:
(1) In winter, it is recommended to reserve at least 30% or 50% of the battery power to avoid low battery power. Especially in snowy weather, it is recommended to maintain 70% of the battery capacity to ensure that the battery has sufficient reserves.
(2) If the battery has not been charged for more than a week, it is recommended to pause discharging until the battery is charged to more than 90% before switching on discharging.
(3) Avoid discharging with high power. PV is weaker in winter and charging is more difficult. If the device is discharged at high power, this can easily lead to the battery having low power for a longer period of time.
(4) Regularly check whether the PV panels can supply power normally. Especially after heavy snowfall, the PV panels are easily blocked by snow and cannot charge the battery for a long time.
