What to do if the green POWER LED is on and the red ALARM LED is on in my Victron energy SUN Inverter?
If the green POWER LED is on and the red ALARM LED is on, reduce the AC load connected to your Victron energy Inverter.
Why is the red ALARM LED blinking slowly on my Victron energy SUN Inverter?
A slowly blinking red ALARM LED on your Victron energy Inverter indicates a low battery. Charge the battery and turn off AC loads. Also, ensure all battery cable connections are tightened, the cables are sufficiently thick, the battery is full, and in good working order.
What should I do if the red ALARM LED is blinking with a fast double pulse on my Victron energy SUN Inverter?
If the red ALARM LED is blinking with a fast double pulse, reduce the AC load on your Victron energy Inverter or move the inverter to a better-ventilated area.
How to fix a Victron energy SUN when the green POWER LED is blinking with a fast double pulse and the red ALARM LED is on?
To resolve this, remove the cause of the overload. Then, restart the inverter by switching it off and then back on again.
How to troubleshoot a Victron energy Inverter when both the green POWER LED and red ALARM LED are off?
First, check the ON/OFF/ECO switch to ensure it is in the ON or ECO position. Try turning the switch to OFF and then back to ON to see if the inverter starts. If not, check the remote on/off connector for a wire loop or the remote switch/panel. Verify the DC cable connections and external fuses, ensuring you measure battery voltage at the inverter's battery connection. If the internal fuse is blown, the inverter requires servicing.
What does it mean when the red ALARM LED is blinking fast on my Victron energy Inverter?
A rapidly blinking red ALARM LED indicates a high DC input voltage. Reduce the DC input voltage, verify the battery voltage is correct, and ensure the battery bank is wired correctly. Check for faulty or incorrect chargers or equipment with a faulty charge regulator.
What to do if the green POWER LED is blinking with a fast double pulse and the red ALARM LED is blinking slowly on my Victron energy Inverter?
To resolve this, charge the battery or switch the inverter off and then back on again to restart it. Check the battery voltage at the battery terminals of the inverter. Also, check the DC fuses, cables, and cable connections.
What does it mean when the green POWER LED and the red ALARM LED are blinking with a fast double pulse on my Victron energy Inverter?
This indicates the inverter is overheated. Wait until the inverter has cooled down; it will automatically turn back on when its internal temperature has dropped to an acceptable level. Improve the ventilation around the inverter or move it to a cooler location.
Why are the green POWER LED blinking with a fast double pulse and the red ALARM LED blinking fast on my Victron energy SUN Inverter?
This indicates a high DC input voltage. Reduce the DC input voltage, check if the battery voltage is correct and if the battery bank is wired correctly. Also check if there perhaps are faulty or incorrect chargers or equipment with a faulty charge regulator.
What should I check if the red ALARM LED is blinking with a fast single pulse at longer intervals on my Victron energy Inverter?
Check if all battery cable connections have been tightened and ensure the battery cables are of sufficient thickness. DC ripple is related to a voltage drop over the battery cables.
