Inverter LED Status Information Solutions Contact UsInverter LED Status InformationUse our guide to gain insight on the LED status on your Sun Bandit® Inverter. Inverter LED StatusWhat Is the Color of the LED?Select An OptionGreenRedGreen & RedOrangeNoneIs the LED Blinking?Select An OptionLED is SolidLED is BlinkingWhat is the LED blinking pattern?Select An OptionBlinking Red for 3 seconds & Green for 1 secondBlinking Red for 1 second & Green for 3 secondsWhat is the Red LED blinking pattern?Select An OptionBlinking red every 1 secondBlinking red every 3 secondsYour LED is Solid GreenInverter is generating power.Your LED is Solid RedGround Fault in Circuit.Disconnect Inverter immediately, locate GF and repair.Remove DC input and verify DC VOC.Keep disconnect off reconnect inverterTurn ON DisconnectYour LED is Blinking Green.Inverter is in a ready state to turn Solid Green and produce power. However, it must first poll the circuit to determine if conditions are correct. Will need sufficient power input from PV modules.Your LED is off.NOT enough Sun on PV modules for system to turn on.DC wired incorrectlyOpen circuit on DC channels (all channels must be closed circuit)Negative and positive crossed between input channelsVerify PV modules are goodLED may be damagedInverter damaged internallyCall Tech SupportYour LED is blinking red for 3 seconds and green for 1.Normal State of Inverter when circuit is open or resistance is incorrectVerify tank temperature is not at maximum setpointVerify thermostat settingsRun resistive check if thermostats are correctly setCall Tech Support only after checking, temperature, thermostat settings, wiring, and resistance check pass.Your LED is blinking red for 1 second and green for 3.Resistive circuit is out of range.Verify resistive range of specific inverter on Specification SheetDisconnect inverterVerify resistive range of entire circuit.See start up procedures in S-100 installation guideCorrect resistive range and reconnectYour LED is blinking red every 1 second.AC is detected in the circuitThis is normally due to improper wiring. Disconnect Inverter immediately and check wiring paying particular attention to ground separation i.e. two separated and isolated ground electrodes. Neutral/ground bond is critical and is already completed in the S-100 at factory.Verify only DC input into input channelsVerify conductors run isolated as not to be exposed to inductance / capacitance.Your LED is blinking red every 3 seconds.Inverter has internal damage call Tech Support to go over wiring .The LED is blinking OrangeTrouble Shooting Note:At least one DC input is over the 58V limit. Disconnect the high voltage DC source(s). Solar panels in cold weather can generate much higher voltage than rated Voc.CommentsThis field is for validation purposes and should be left unchanged.
