Operating the PV inverter Parameter Mode adjustable values ON I OFF Curve a Curve B This switches the feature on and off. Default mode is OFF. *These values are only adjustable if Country setting is Italy CEI-021 or Italy A70. This means the inverter will feed in reactive power depending on the active power once the grid voltage is higher than Lock-in Voltage. When grid voltage is lower than Lock-out voltage then inverter would go back to pure active power control.

Operating the PV inverter 7.3.6.5 reactive Power Control for Slovenia (SOnDO) for 15 / 20 / 30 TL When selecting Slovenia from the Country setting list on initial start up, it is possible to adjust reactive power parameters for Q(V) according to two curves, class B and class C. The Slovenian requirements are known as SONDO or SOIEDN (System operation instructions for electricity distribution network). Q(V) is the reactive power ratio Q/Sn in dependency of the voltage V.

Maintenance 8. Maintenance In order to ensure the normal operation of the PV Inverter, please check it regularly at least once every 6 months. Check that all the terminals, screws, cables are securely in place. If there are any damaged parts, please contact a qualified technician to repair it or to replace it with a new spare part. To ensure that no foreign contaminants enter the warm air outlets, please have them cleaned every 6 months by qualified technicians.
Maintenance 1. 2. 3. 4. Figure 8.1.
Maintenance 8.2 replace a Fan assembly If one of the fans has failed it is necessary to order a new fan assembly and replace it. User should remove the fan bracket with faulty fan as shown in figure 8.1. Four thumb screws (circled below) attach the fan bracket to the inverter. Loosen the 4 thumb screws and pull the fan bracket from the inverter carefully and then disconnect the four pairs of fan electrical connectors (or single pair of fan electrical connectors for 6.0 / 8.0 / 10 / 12 TL).
Maintenance Designation FAN ASSEMBLY FOR SOLIVIA 30 TL Part number Delta EOE90000531 Table 8.1.: Fan Assembly Part Numbers 8.3 Cleaning the air Outlets Figure 8.3 shows the removal of the vent covers for cleaning. First remove the 4 screws that hold the vent cover to the inverter enclosure. Next, remove the vent cover from the inverter. With the vent cover removed, clean it on both sides. After cleaning one of the vents, proceed to take off the vent on the opposite side and clean in the same manner.
