outine maintenance

Scheduled maintenance operations are not mandatory, but are recom-

mended to preserve the efficiency of the PV plant.

We recommend that maintenance operations be carried out by qualified personnel or by the

personnel of ABB (as set forth in a maintenance contract).

The periodicity of the maintenance operations may vary in accordance with local environmen-

tal conditions and the installation

Table: routine maintenance

Annual visual inspection

• Check that the inverter is operating correctly, and that no fault alarms are present

• Ensure all the labels and safety symbols are visible

• Test the integrity of the cables, connectors, and plugs external to the inverter

• Check that the environmental conditions have not changed drastically since

the installation of the system

Annual operations

• Check that cable glands and connection block screws are tight

• Check that the wiring box cover is properly closed

• If no monitoring system is present, check the history log of alarms and errors

using the instructions given in the manual in order to look for recent malfunction

warnings

Annual cleaning

• Clean the equipment; in particular the bottom grille of the wiring box and the

heat sink

roubleshooting

Follow the table shown in the following paragraph in order to understand

and resolve warning (Wxxx) and error (Exxx) messages displayed by the

inverter

The operations carried out on the inverter in order to identify and resolve malfunctions may be

carried out only by the organization that carried out the installation or by qualified personnel

larm Messages

The equipment is able to indicate errors/warnings on the display only if

the

input voltage is higher than the Vdcmin voltage (POWER LED flash

ing or on; see operation chapter).

The messages and their codes are indicated on the highlighted part b10

of the display

The following table gives the complete list of errors/warnings relating to string inverters. Some

error/warning codes may not be used depending on the inverter model installed.
