4.1 Power, GFDI and Error LED Indicators
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 0.75A midget fuse 500V DC or 600V DC rated
such as Solectria Renewables P/N KLK ¾ or KLKD 3/4, or Bussmann, KLK-3/4 or KLKD-3/4.
