The LED indicators mounted on the right-hand side of the enclosure just above the DC disconnect give the user a 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 – 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 solid.
