Damage AC output part MOS tube caused by overload of the inverter of BP/BPlus/Helios II Series


BP series pure sine wave inverter/ BPlus Series pure sine wave inverter/ Helios II Series off grid solar inverter


The inverter still ran even after short circuit because of a full load in AC output, which damaged AC output part MOS tube.

Fault Causes

The inverter still overloaded after short circuit/overload.

Solutions and steps

Change MOS tube.


If it is serious, MOS tube will explode as the image shows.
