Working Principle
The inverter works in two stages. During the first stage, the DC to DC converter
increases the DC input voltage from the power source (eg.A 12V battery) to 300V DC
In the second stage, the high voltage DC is converted to the watts you need (AC) using
advanced power MOSFET tran-sistors or IGBT technology in a full bridge configuration
The result is excellent overload capability and the capacity to operate difficult reactive loads
Connection Method
3-3-1.Attach the ring type connector marked with redto the positive (+) DC terminal
on the inverter and attach the ring connector marked with black to the negative (-) DC
terminal.
CAUTION!
A reverse polarity connection (positive to negative) may damage the inverter (Fuse)
Damage caused by a reverse polarity connection would probably invalidate your warranty
WARNING: Sparking may occur when connecting the unit to the battery, make
sure no flammable fumes are present before making any connections.

3-3-2. Tighten the nut on each DC terminal by hand until it is snug. If the power more
than 1800W, please use tools to tight up the screw.
3-3-3. When the inverter is not in use , unplug it from the 12V/ 24V /48V DC
outlet to avoid the battery s’d i scharge.
CAUTION: Before using the inverter,please provide a ground connection wire. On
the rear panel of the inverter is at erminal fitted with a nut for connecting to the inverter
and to the earth terminal of the AC output socket. Please choose heavy duty, insulated
green/yellow wire. Drive into the ground to a depth of 1-2m or more. In a vehicle,
connect the inverter to the chassis of the vehicle. In a boat, connect to the boatˋs
grounding system.
Batteryˋs C harge
We advise that please use deep cycle battery. If you hear the low voltage alarm, please stop
the inverter immediately. When the battery is fully charged, the inverter can be used again. If
you use the inverter in a car, then it would be necessary to run the engine of your car after
each time you use the inverter. You can run the engine for 10 minutes or so to recharge the
battery.

3-5-1. When a 12V/24V/48V DC outlet or battery properly connected to the inverter,
turn on the ON/OFF, the green Power indicator will light, and it deliver AC power to the
outlets.
3-5-2. Plug the AC appliances you wish to operated into the AC outlet (s) and switch
your appliances on, switch one at a time.

NOTICE: When connect to the appliances,remember to turn on the inverter
before turn on the appliance.
3-5-3. If the audible alarm be ignored the inverter may be automatically shut down
when the battery voltage drops to 9.8-10.2V / 19.6-20.4V / 39.2-40.8V. in order to
prevent damage to the battery from excessive discharge.
3-5-4. If the AC appliances rated power is higher than inverters rating(or the appliance
draws excessive surge power),the inverter will shut down. The red FAULT indicator will light.
3-5.5. If the inverter exceeds a safe operating temperature, due to insufficient.
ventilation or a high surrounding temperature , it will automatically shut down. The
red FAULT indicator will light and the audio warning alarm will sound.

Guidelines
3-5-6. If a defective battery charge system has caused the battery voltage to rise
to a dangerously high level, the inverter will automatically shut down.
3-5-7. The cooling fan is designed to operate only when the temperature goes up or
when the loads are applied.
!
CAUTION: Although the inverter incorporates the protection function against
over-voltage, there would be still the possibility of getting the unit damaged
if the input voltage exceeds 16V/32V/64V.
