MAINTENANCE AND TROUBLESHOOTING
10.1
Maintenance
Maintaining the solar inverter VACON 8000 SOLAR is simple. It is recommended that the following
checks are carried out at least once a year.
•
Visually check the external condition of the inverter, checking mainly the good condition of
•
the door and its locking elements.
•
Visually check the internal condition of the inverter, checking mainly that wires are correctly
•
located, wearing of isolation of wires, lack of hot points on checking the color of terminals
•
and isolations. Check also for humidity and the correct fixing of the elements of the inverter.
•
Check the tightness of connection screws on the terminals.
•
Check that the fans operate correctly. Check if they need to be cleaned.
•
Clean the ventilation grids.
•
Check that the acoustic noise produced by the inverter has not increased.
If there is something wrong, please contact the installer.
10.2
Troubleshooting
The microprocessor for the Vacon solar inverter continuously monitors the running condition of the
inverter and the elements connected to it.
If the microprocessor finds any abnormal running values or that some of the elements do not work
correctly, the device issues an alarm signal, if the malfunction does not imply any kind of a safety
hazard for the inverter or the installation, and it issues a fault signal if there is any kind of a safety
hazard for the inverter or the installation.
Every indication of fault or alarm is shown on the control panel described in chapter 6. In the
control panel, the letter A (Alarm) or F (Fault) appears together with the order number of the Fault
or Alarm, the fault or alarm code and a short description.
The fault can be reset using the reset push button on the control panel.
Below you can find the fault and alarm codes, their causes and how to solve them.
Only a qualified electrician may carry out the maintenance work. There is risk of
electric shock.
No maintenance must be given unless the unit is reliably isolated from AC and
DC power sources.
Safety instructions included in chapter 1 must be followed.
THE SOLUTION FOR SOME OF THE PROBLEMS INDICATED HERE IMPLIES TO
PERFORM CHECKING INSIDE THE INVERTER, THE WIRES OF AC MAINS OR THE
DC WIRES IN THE SOLAR PANELS. THESE CHECKS HAVE TO BE CARRIED OUT
TAK ING THE INSTRUCTIONS IN CHAPTER 1 INTO ACCOUNT.
REPAIR WORK SHOULD ONLY BE CARRIED OUT BY A QUALIFIED TECHNICIAN.
THERE IS A RISK OF AN ELECTRIC SHOCK.
