Why is the OVERLOAD LED on my Majorpower Corporation Majorsine Inverter?
The OVERLOAD LED is on because the power drawn from the Majorpower Corporation Inverter exceeds its load rating. To resolve this, remove unnecessary loads or redistribute them to other inverters.
What to do if FAULT LED lights and LCD shows OVERTEMPERATURE on Majorpower Corporation Inverter?
If the FAULT LED lights up on your Majorpower Corporation Inverter, accompanied by an LCD OVERTEMPERATURE message, it indicates that the temperature inside the inverter is too high. You should check for blocked vents or a non-working fan.
Why is the “FAULT” LED lighting up on my Majorpower Corporation Majorsine Inverter?
The FAULT LED might light up on your Majorpower Corporation Inverter due to several reasons. One potential cause is an output short, which suggests the load may be abnormal. Other causes, like Bypass AC fail or Inverter failure require calling for service.
How to fix LEDs that do not light up on Majorpower Corporation Majorsine?
The LEDs on your Majorpower Corporation Inverter might not light up due to several reasons. The circuit breaker may be off; if so, turn it on or reset it. Another possibility is incorrect DC cable polarity installation, which requires applying the correct DC polarity. Finally, the DC input may be over or under voltage, so apply the correct DC voltage.
