1. Switch off DC and AC side circuit breakers and switches.
2. Wait until the screen is on and set up grid connection standard. (Please refer to 7.4.1 for specific
operations)
The inverter starts up and feed into the utility grid automatically when all the necessary conditions of
normal operation for the inverter is fulfilled.
3. Check whether the display and LEDs are indicating a normal operating state.
Sign Color Instructions
POWER Green On: Power On
COM Green On: Normal Operation and feed into the utility grid
FAULT Red Flash: Check wiring
7.3 Anybuild Series LED Display
Three LED lights are assembled on the inverter, COM, POWER, FAULT. When DC and AC power are normal
and the inverter starts up,the POWER LED turns on.When the inverter is operating and feed electricity into
the utility grid normally, the COM LED turns on. When there is faulty in the PV system or inverter, the FAULT
LED flashes, and the faulty code will be shown on LCD screen.
POWER LED (Green)
POWER LED turns on when DC voltage reaches the start-up voltage and turns off when it falls below a
certain value. POWER LED is on represents inverter is active and so is the inverter control system. If POWER
LED is off, inverter cannot be normally started up.
Under normal operation conditions, when sun light is sufficient, inverter start up generates electricity in the
morning and stops after dark. This procedure may repeat several times in one day, especially in morning
and at night. It is a normal working phenomenon but not a wrong signal.
COM LED (Green)
The COM LED turns on when the inverter start to feed electricity into grid. And the COM LED is off when
the inverter is standby.
FAULT LED Flashes (Red)
Red FAULT LED flashes means the on-grid generation is stopped due to some faults. Please wait 10 minutes
to be sure whether the fault is temporary. If yes, inverter will automatically restart again. If not, contact
after-sales personnel.
