The alarm sounds 1 time per
time, after 2 seconds, same
beeps again.
The input voltage is very
low. DC12V inverter: 10-
10.5V DC24V inverter: 20-
21V
1. Ensure enough and full battery power.
2. Check that the battery cables are suitable for transporting
the DC voltage. Use a thicker or shorter cable.
3. Setting DC input circuit connections
The alarm sounds 2 times
per time, after 2 seconds,
same beeps again.
The input voltage is too
low and the inverter stop
working.
1. Ensure enough and full battery power.
2. Check that the battery cables are suitable for transporting
the DC voltage. Use a thicker or shorter cable.
3. Checking DC input circuit connections.
The alarm sounds 3 times
per time, after 2 seconds,
same beeps again.
The input voltage is too
high. DC12 inverter:
higher than 15.5V;DC24V
inverter: higher than 30V
1. Check that the voltage at the input DC terminals does not
exceed 15v
2. Make sure that the maximum voltage of the battery
controller does not supply voltages higher than 15v(30V)
3. Check that we are not using a panel or wind turbine not
regulated for battery charging
The alarm sounds 5 times
per time, after 2 seconds,
same beeps again.
（
The
alarm is beeping
repeatedly
）
The load AC exceeds the
nominal power by 120%.
Short circuit in
connection.
1. Disconnect the inverter
2. Disconnect the load
3. Reduce load
4. Connect the appliance first, turn on the inverter switch
after turning on the appliance switch
The alarm sounds 4 times
per time, after 2 seconds,
same beeps again.
Inverter overheating
Check that the fan is working correctly, Try again when the
inverter has been cool down.
Got 115VAC or so while
testing inverter's ground
wire and Neutral line ?
This voltage is an
electromagnetic induction
voltage, there is no
current leakage.
This is normal. Inverter output communication does not
distinguish hotline and neutral line, if you need to distinguish
the hotline and neutral line, please contact customer service
or after-sales technology.

IMPROPERUSE OF POWER INVERTER
1. Reverse polarity: For the models which have reverse polarity protection, inverter's fuse will blow out to protect the
other part inside the inverter when the inverter is connected reversed. It is possible to damage the part of the positive
and negative terminals due to high current after a short circuit. It will not affect the normal use after changing the fuse.
For the model which is not equipped with reverse polarity protection, it is possible that the electrolytic capacitor and
the Mosfet will burn out. When this occurs, a crack sound can be heard and smoke will be seen coming out.
2. When the input voltage exceeds the allowable voltage range of the inverter, the electrolytic capacitor inside the
inverter will burn out. In this case, a crack sound can be heard and smoke will be seen coming out.
3. Heavy overload. The overload protection power of the inverter is 10% higher than the rated Watts, mainly used to
start some appliances which require high start current. It doesn't support a long-term use. If customer uses the inverter
for long period of overload, it may cause aging of electronic parts and rapid increase of machine temperature. In more
serious cases, the electrolytic capacitor inside the inverter will burn out. If so, a crack sound can be heard and smoke
will be seen coming out.
4. The power inverter is used outdoor during rainy days or when water gets into the inverter. Because the inverter is
not waterproof, water entering any electronic part will cause short circuit and corrosion of such electronic parts.
Failure to dry after water entry will cause the electronic components to burn. When this occurs, a crack sound will be
heard and smoke will be seen.
