PVI13KW Installation and Operation Manual
DOC-020028 rev 006 19
Operation:
The control electronics and DSP will be active as soon as DC (PV) voltage reaches 200V DC.
The inverter will go on-line with the utility/building 3-phase grid when the DC voltage first
exceeds 250V DC. Next, the inverter will load the array, bringing the DC voltage down from
250V DC to not less than 225V DC.
Once there is enough PV power at 225V DC to back feed 3-phase AC power switching will
automatically feed power to the grid.
Because the inverter goes completely off line at night or in dark conditions when no power can
be produced, there are no idling losses, adding 1-2% additional energy production annually over
an inverter design that remains on all the time.
Operating states, GFDI status and error indications shown by the LED indicators, which are
described in chapter 4, “Power, GFDI and Error LED Indicators”.
4 Power, GFDI and Error LED Indicators
The inverter operates automatically without the need for user interaction or maintenance.
The PVI13KW automatically starts back feeding 3-phase AC power into the grid every morning
as the sun rises, as soon as sufficient DC voltage and PV power is available. The inverter DSP
runs through various checks before going online with the grid and feeding power into the grid.
The LED indicators mounted on the right-hand side of the enclosure just above the DC
disconnect give the installer and user a good, quick look at what state the inverter is in and if it is
operating normally.
GREEN – indicates “power”, the unit is powered up and/or feeding power to the grid
RED – “ERROR” or “FAULT”, the inverter is not providing power due to an error or fault
RED & YELLOW – together indicate that a ground fault has been detected and it must be
located before the inverter will function. Check GFDI fuse if RED LED remains as solid.
If the GFDI fuse is blown, see “Opening the Main Enclosure” section and Fig. 9, “Description
and Location of Components”. Follow these instructions carefully (disconnecting AC & DC
power) and locate, check and replace the GFDI fuse with a 3A midget fuse 500V DC or 600V
