6. MAINTENANCE & TROUBLESHOOTING
6.1 VISUAL INSPECTION

Inspect the inverter and the cables for visible damage and pay attention to the operating status display of
the inverter.

Before maintenance, you must disconnect AC and DC to avoid risk any shock.

In case of any damage, notify your installer. Repair may only be carried out by authorised eletricians.
PLEASE CARRY OUT VISUAL INSPECTION AT LEAST ONCE OR TWICE A YEAR.
6.1.1 CLEANING THE INVERTER EXTERNALLY

Only use completely dry cloth/tissue to clean the inverter.

Only the exterior of the inverter should be cleaned.

Use a soft and dry brush to remove dust from the fan cover and from the top side of the inverter on a
regular basis.
LETHAL VOLTAGES ARE STILL PRESENT IN THE TERMINALS AND CABLES OF THE INVERTER EVEN
AFTER THE INVERTER HAS BEEN SWITCHED OFF AND DISCONNECTED.
6.1.2 BATTERY MAINTENANCE

Batteries should not be discharged more than 50% of their capacity on a regular basis. Under extreme
conditions (such as a severe storm or a long utility outage), cycling to a discharge level of 80% is
acceptable.

Totally discharging a battery may result in permanent damage and reduced life. Our PCUs limit the depth
of discharge to 60% to prolong the life of the batteries and save on your battery costs in the long run.
6.1.3 PV MAINTENANCE

PV Panel surface should be clean.

PV Panel should be replaced in case of any damage of upper layer (Non reflective layer).

PV Panel should be checked regularly to ensure that it is receiving maximum sunlight possible.
