Check out if the AC load is
within the rated power or
whether there is load short.
Improve
ventilation and do not block
the vents. Restart the inverter
when it is cool down.
Remove all the connected

load and line. If the LED
keeps red, the inverter has
inside faults and should be
returned to the factory
