CAUTION
• Protect the battery system from damage during transportation and storage.
• The transportation must be carried out by trained professionals. All operations during the
process have to be recorded.
• Keep the equipment stable to avoid dumping, which can result in equipment damage and
personal injuries.
• Place the cables at least 30mm away from the heating components or heat sources,
otherwise the insulation layer of the cables may be aging or broken due to high
temperature.
• Tie the cables of the same type together, and place cables of dierent types at least 30mm
apart. Do not place the cables entangled or crossed.

08 Maintenance
Item Period
Fully charge the battery and discharge it to 25~50% if the
battery is not in use.
Check the wall mounting plate, x it if it is not secured. Once Every 6 months
Check whether the outer shell is broken. Repair the painting or
contact after-sales service if there is any broken.
Check whether there is an exposed cable. Replace the exposed
cable or contact after-sales service for help.
Check whether there is debris accumulation around the battery
to avoid aecting heat dissipation.
Check for water and pest to avoid prolonged intrusion. Once Every 6 months
WARNING
• Please contact after-sales for help if you nd any problems that may inuence the battery
or the inverter. Disassemble without permission is strictly forbidden.
• Please contact after-sales for help if the conductive wire is exposed because high voltage
danger exists. Do not touch or disassemble privately.
• In case of other emergencies, contact the after-sales as soon as possible. Please operate
following the guidance of the after-sales, or just wait for the after-sales service operators.
Remove the Plastic Cover
Gently pry up two clips on one side using a screwdriver to remove the plastic cover.
