2.2. Safety Instructions for Battery
2.2.1. General Safety Precautions
Overvoltage or wrong wiring can damage the battery pack and cause deflagration,
which can be extremely dangerous.
All types of breakdown of the battery may lead to a leakage of electrolyte or
flammable gas.
Battery pack is not user-serviceable. There is high voltage in the device.
Read the label with Warning Symbols and Precautions, which is on the right side
of the battery pack.
Do not connect any AC conductors or PV conductors directly to the battery pack
which should be only connected to the inverter.
Do not charge or discharge damaged battery.
Do not damage the battery pack in such ways as dropping, deforming, impacting,
cutting or penetrating with a sharp object. It may cause a leakage of electrolyte or
fire.
Do not expose battery to open flame.

6. Maintenance and Troubleshooting
6.1. Routine Maintenance
Normally, the energy storage system need no maintenance or calibration.
However, in order to maintain the accuracy of the SOC, it is recommended to perform
a full charge calibration for SOC (charging battery until the charging power is 0) on
the battery at regular intervals (such as two weeks).
Disconnect the system from all power sources before cleaning. Clean the housing,
cover and display with a soft cloth.
To ensure that the energy storage system can operate properly in the long term, you
are advised to perform routine maintenance on it as described in this chapter.
