Maintenance Guide
Routine Maintenance
Only authorized personnel are allowed to carry out the maintenance operations and are
responsible for reporting any anomalies.
Always use the personal protective equipment provided by the employer when carrying out
maintenance.
During normal operation, check that the environmental and logistic conditions are appropriate.
Make sure that the conditions have not changed over time and that the equipment is not exposed
to adverse weather conditions and has not been covered with foreign bodies.
DO NOT use the equipment if any problems are found, and restore the normal conditions after
the fault has been corrected.
Conduct an annual inspection on various components, and clean the equipment with a vacuum
cleaner or special brushes.
Firmware version can be checked by using the monitoring system.
Always de-energize the AC branch circuit before servicing.
Do not attempt to dismantle the Micro-inverter or make any internal repairs! In order to
preserving the integrity of safety and insulation, the Micro inverters are not designed to allow
internal repairs!
Maintenance operations must be carried out with the equipment disconnected from the grid (AC
power switch off) and the photovoltaic modules shaded or isolated, unless otherwise indicated.
For cleaning, DO NOT use rags made of filamentary material or corrosive products that may
corrode parts of the equipment or generate electrostatic charges.
Avoid temporary repairs. All repairs should be carried out using only genuine spare parts.
Storage and Dismantling
If the equipment is not used immediately or is stored for long periods, check whether it is
correctly packed. The equipment must be stored in well-ventilated indoor areas that do not have
characteristics that might damage the components of the equipment.
Take a complete inspection when restarting after a long time or prolonged stop.
Please dispose the equipment properly after scrapping, as component parts are potentially
harmful to the environment, in accordance with the regulations in force in the country of
installation.
