Model
BPlus series pure sine wave inverter 300W 12VDC 220VAC
Description
The inverter can be started up but its output voltage is unsteady.
Fault Causes
R18 resistance in bus voltage has been damaged, the transient current is too large so the back end shortcircuits.
Solutions and steps:
Change R18 resistance.
