Storage location requirements:
⚫ The storage location of the energy storage system should have sufficient bearing capacity
(single cabinet ≥ 4t), the ground needs to be level, the flatness should be ≤ 3mm, no slope, and
there is no accumulation of materials around.
⚫ Before storage, the energy storage system should be reasonably padded according to the local
meteorological conditions, to avoid rain or ground water erosion;
⚫ The storage location should avoid mechanical impact, heavy pressure and strong magnetic
field action.
Regular inspection:
⚫ Inspect at least once every half a month to check whether the packaging is intact and
undamaged to avoid insects and rodents, and replace it immediately if it is found to be damaged.
Before installing the energy storage system for long term storage (more than 6 months), it should be
inspected and tested by professional personnel before it is put into use.
⚫ Long-term storage of batteries is not recommended due to the capacity degradation that
occurs when batteries are stored for long periods of time. In addition to this, even if the battery is
stored at the recommended optimal storage temperature, there will be irreversible capacity
degradation due to calendar effects, the longer the storage time, the greater the irreversible degradation,
please refer to the technical agreement for specific degradation values. Stock batteries are shipped on
a first-in-first-out basis.
⚫ Calculated from the date of shipment, energy storage systems with a storage period of more
than 6 months under the above conditions should be charged and discharged once to bring the system
SOC up to 30%~40%, and the SOC needs to be consistent after replenishment.
⚫ The air inlet and outlet of the energy storage system should be protected, and effective
measures should be taken to prevent the intrusion of rainwater, sand and dust into the interior of the
energy storage system.
