11 Maintenance
SolarMax inverters are basically maintenance-free. However, to ensure perfect
operation over the course of several years, in addition to regular controls of the operating
and yield data via the inverter display or remote monitor we also recommend having the
simple maintenance work described below performed at regular intervals. The mainte-
nance intervals must be set keeping the ambient conditions in mind (especially exposure
to dust).
Inspections by the plant operator
The following checks can be performed by the plant operator. If you discover problems
while performing these checks, contact the electrician in charge of maintenance or our
SolarMax Service Centre.
■ Functional check of the inverter using the graphics display
■ On-site check of visible traces of wear and tear (damage, rain, snow, rodents, etc.)
■ Cleaning and check of plant room
■ Cleaning the fan screen
12 Removal
The device does not have to be opened for demounting.
Procedure
DANGER
■ The PV generator supplies direct current to the inverter when the PV modules are
exposed to sunlight.
■ The inverter‘s heat sink (the base of the device) can reach temperatures as high as
80 °C.
1. First disconnect the device from the mains on the AC side via the AC line protection
breaker or the fuse.
2. Then open the DC insulation switch in order to disconnect the inverter from the PV
generator  eld. Now remove the connectors.
3. After disconnecting the inverter wait at least 5 minutes before opening the device to
permit internal capacitors to discharge.
