Note:

When the energy storage is working,the fan will accour a certain sound when it dissipates heat,just like our computer,which is normal.

Storage and Downtime Maintenance:

1.It is suggested to fully charge it at least once every 90 days for maintaining the best performance, reliability, and longevity.
2.If outputting is done, please remember to turn off the master to save the loss of energy.
3.Due to the chemical characteristics of the battery, the available capacity of the battery may somewhat vary from environment to environment such as cold weather or overheating (you may hear a cooling fan). So please always use it in room temperature (0°C- 40°C）also it is not recommended for outside storage or in damp environments.
4.If you are living off-grid in sub-zero conditions, we recommend you keep your unit in an insulated cooler and connect to a power source(solar panels). The natural heat generated will keep battery capacity at its highest.
5.The battery packs inside are non-removable, nondisassemble, the life-cycle for charge and discharge is over 500 times, but eventually, it will wear out.
6.Continuously discharging the battery to 0% and then storing it with an empty battery may reduce its serviceable life. It is recommended to always leave at least 20% capacity unused.
