Precautions
• If the ambient temperature for storage is between 30°C and 50°C (86°F to 122°F),
please recharge the battery modules at least once every 6 months.
• If the ambient temperature for storage is between -20°C and 30°C (-4°F to 86°F),
please recharge the battery modules at least once every 12 months.
• For the first installation, the interval among manufacture dates of battery modules
shall not be exceed 3 months.
• If a battery module is replaced or added for capacity expansion, each battery's SOC
should be consistent. The max. SOC difference should be ±5%.
• If users want to increase their battery system capacity, please ensure that the SOC of
the existing system capacity is about 40%. The manufacture date of the new battery
module shall not exceed 6 months. If the manufacture date of the new one exceeds 6
months, please charge it to around 40%.
