16. PROTECTION FEATURES
Low Voltage Protection: when the battery is in discharged condition, the inverter will shut down, at the same
time, an alarm will sound and the indicator light will turn on.
Over-voltage protection: when the input voltage exceeds rated voltage, the inverter will shut down, at the same
time, an alarm will sound and the indicator light will turn on. A substantial excess of the rated voltage, for
example, at 100V on a 24V inverter will destroy the inverter!
Reverse polarity protection: when the inverter is connected reversely, inverter’s fuse will blow out to protect
the inverter. The DC input side with MOSFET protection will not work.
You have to replace all burnt fuses.
Overload protection: when the continuous draw exceeds rated Watts, the inverter will shut down, at the same
time, an alarm will sound and the indicator light will turn on.
Short circuit protection: when the output side is short circuited, the inverter will shut down, an alarm will sound
and the indicator light will turn on.
Temperature control: If the temperature in the unite reaches 45°C the fan will start and cool down the device.
Over-temperature protection:when the inside temperature is over 75°, the inverter will shut down, an alarm
will sound and the indicator light will turn on.
17. SERVICE ENVIRONMENT
Ambient temperature:-20~+50℃
Storage temperature:-40~+85℃
Relative humidity: 0~85% Non condensing
18. PROBLEM CAUSES
PROBLEM POSSIBLE CAUSE SOLUTION
The inverter is switched on
but the LED does not work.
No response. No alarm.
Open circuit. No DC input.
Fuse faulty.
1. Check entry circuit continuity
2. Check that the battery fuse is right.
3. Check if all circuit connections are correct.
4. Check the on/off button wiring.
The inverter is switched on
and the LED works. No AC
output. No alarm.
Reversed of polarity
connection on input side
and internal fuses have
been burnt.
1. Check and correct the polarity of input connections and
replace the internal fuse. (NOTE: Reversing the polarity may
cause irreversible damage to the circuit)
Unusual Low output AC
voltage
Poor battery. Internal
MOSFET faulty. Drive
circuit faulty.
1. Reverse the
potentiometer on drive panel to get right
output voltage.
2. Ensure enough and full battery power..
3. Contact the technical support.
The alarm sounds 1 (2) time
per time, after 2 seconds,
same beeps again. (Without
any load)
Poor battery. Connection
cable is too thin or too
long.
1. Ensure enough and full battery power.
2. Use the original cable.
