Solution
1. Check whether cables to
mains are disconnected,
loose, or incorrectly
connected.
2. If cable connections are
correct, measure the mains
voltage with a multimeter.
If the mains voltage
exceeds 280 V, the mains
input is not normal; if the
mains voltage is less than
272 V, the sampling circuit
of the power module is not
normal. Replace the faulty
module.
3. Check whether the output
or battery is incorrectly
grounded.
