•Before any operation, please disconnect the DC switch and AC switch, and
wait for at least 5 minutes until internal capacitance discharge completely.
•It must be carried out by qualified, trained personnel and comply with all
prevailing local code and regulations.
•Please disconnect the DC switch and AC switch before any operation, and
wait for at least 5 minutes until the internal bus capacitance discharge
completely.
•Do not use the air pump cleaning fan, which may cause fan damage.
When the Growatt MAX-X series inverter work in high temperature environment, good
ventilation and heat dissipation can effectively reduce the chance of load derating.
Inverter equipped with internal cooling fans, when the internal temperature is too high,
the fans work in to reduce the internal temperature. When the inverter is derating
because of the internal temperature is too high, the following are the possible reasons or
solutions.
1
)
Fan is blocked or the heat sink gathers too much dust, it needs to clean the fan, fan
cover or heat sink.
2
)
Fan is damaged, it need to replace the fan.
3

Fan cleaning and replacement procedure;
1>Please ensure that the DC side and AC side of the inverter have been disconnected
before cleaning or replacement of the fan.
1) Turn off DC switch.
2) Disconnect DC terminals from inverter(Users need tools to disconnect the DC
connection terminals).
3) Turn off AC switch.
2>Remove the screws on the fan guards with a cross screwdriver. it is shown as below.

DANGER
WARNING
1>Check the ambient temperature and dust of the inverter, clean the inverter when
necessary.
2>Observe whether the air outlets is normal, when necessary, clean the air outlets or
clean the fan step by step, steps refer to 9.1.2.
