5 Trouble Shooting
The PVI13KW is designed, produced and rigorously tested for long life and reliability in a wide
range of climate conditions, voltage and power levels.
With a properly shipped, sited, mounted, wired and tested installation, the integrated PVI13KW
inverter unit should give many years of trouble- free and maintenance- free service.
The following trouble shooting information will help in the event that the inverter does not
function, stops functioning or does not provide full performance.
WARNING:
Before attempting to open disconnects or the main enclosure, read
the entire manual, especially warning messages and “Opening The Main Enclosure”
later in this section. Only qualified personnel sho uld attempt to open any of these
enclosure doors or do any service or troubleshooting.
PV system not functioning
•
Check LED indicator status
•
Check connection to grid, 3-phase AC power
•
Check DC (PV) string connections or main PV feed conductor connections
•
Verify PV voltage range including hot module temperature MPP voltage and cold module
temperature, open circuit voltage (OCV)
•
Contact installer or Solectria Renewables if malfunction persists
•
If contacting Solectria Renewables for assistance, please provide part number, serial
number, short description of problem (LED indicator status, when problem started, how
often problem occurs, under what conditions the problem occurs) and information on PV
modules (string layout, number of modules per string, number of strings, module model
and part number, output power, short-circuit current and open circuit voltage)
Some specific problems that can be identified quickly
GFDI Problem: If the LED indicators show a ground fault problem but the GFDI fuse is not
blown then a ground fault in PV array or wiring must be found. If the LED indicators show that
the GFDI fuse is blown, the fault in PV array or wiring must be found and GFDI fuse replaced.
For fuse replacement, see section 4 “Power, GFDI and Error LED Indicators”.
Inverter over heating and power derating. If the power output is lower than normal and there is
an LED indication of power derating due to high temperature, check the following
•
Is the ambient air temp above 45
o
C?
•
Is the intake (front) louver grill or output (bottom) visibly blocked?
