Restart the inverter only after removing the fault that impairs safety performance.
As the inverter contains no component parts that can be maintained, never open
the enclosure, or replace any internal components.
To avoid the risk of electric shock, do not perform any other maintenance opera-
tions beyond those described in this manual. If necessary, contact your distributor
first. If the problem persists, contact SUNGROW. Otherwise, the losses caused is
not covered by the warranty.
Touching the PCB or other static sensitive components may cause damage to the
device.
• Do not touch the circuit board unnecessarily.
• Observe the regulations to protect against electrostatic and wear an anti-static
wrist strap.
10.2.2 Routine Maintenance
Item Method Period
General status of
the system
• Visual check for any damage or defor-
mation of the inverter.
• Check any abnormal noise during the
operation.
• Check each operation parameter.
• Be sure that nothing covers the heat
sink of the inverter.
Every 6 months
Electrical
connection
Check whether there is damage to the
cables, especially the surface in contact
with metal.
6 months after commis-
sioning and then once or
twice a year
10.2.3 Replacing the Button Cell
Disconnect the inverter from the grid first, then the PV strings and the battery be-
fore any maintenance work.
Lethal voltage still exists in the inverter. Please wait at least 10 minutes and then
perform maintenance work.
There is a button cell on the inner PCB board. Contact SUNGROW for replacement when
the relevant fault alarm occurs.
