Safety First

WARNING! Shock hazard. Keep away from children.

1-1. The inverter generates the same potentially lethal AC power as a normal household wall outlet. Treat it as if you are using any other AC outlet.

1-2. Do not insert foreign objects into the inverter’s AC outlet, fan or vent openings. 

1-3. Do not expose the inverter to water, rain, snow or spray.

1-4. Do not under any circumstance, connect the inverter to AC power.

WARNING! Heated surface.

1-5. The inverter housing may become uncomfortably warm, reaching 140F (60℃) under  extended high power operation. Ensure at least 2 inches (5 cm)of airspace is maintained on all sides of the inverter. During operation, keep away from materials that may be affected by high temperature.

WARNING! Explosion hazard.

1-6. Do not use the inverter in the presence of flammable fumes or gases, such as in the bilge of a gasoline powered boat, or near a propane tanks. Do not use the inverter in an enclosure containing automotive-type, lead-acid batteries. These batteries, unlike sealed  batteries, emit explosive hydrogen gas which can be ignited by sparks from electrical connection。

CAUTION!

1-7. Do not connect live AC power to the inverter’s AC outlets. The inverter will be damaged even if it is switched OFF.

1-8. Do not expose the inverter to temperatures exceeding 104F (40℃). CAUTION! Do not use the inverter with the following equipment:

1-9. Small battery operated products such as rechargeable flashlights, some rechargeable shavers, and nightlights that are plugged directly into an AC receptacle to recharge.

1-10. Certain battery chargers for battery packs used in hand powered tools. These chargers  will have warning labels stating that dangerous voltages are present at the charger’s battery terminals.

1-11. Note, DC voltage of battery should be similar to input DC voltage of power inverter (for example DC12V of battery should be connected with input voltage 12V of the inverter).

Pure sine wave and modified sine wave inverters

The inverter come in two types; pure sine wave power type and modified sine wave type. In the pure sine wave power inverter, the 240V AC output harmonically follows a smooth sine  wave and is almost identical to normal mains electricity. As a result, the pure sine wave  output would be better for most appliances than the modified sine wave output.

A Graphic Comparison of Modified Sine Wave and Pure Sine Wave is shown below:

Guidelines

Installation Conditions

For safe and optimum performance, install the inverter in a location that is:

  1. Dry-Do not expose to water drips or spray. Dry-Do not expose to water drips or spray.
  2. Cool-Operate only in ambient temperatures between 32 °F (0 °C)and 104 °F (40 °C). Keep away from heating vents or other heat producing equipment.
  3. Safe -Do not install inverter in a compartment with batteries or flammable liquids, such as gasoline or explosive vapors.
  4. Well ventilated -Allow at least 2 inches (5 cm)clearance above and on all sides of the unit for proper cooling.
  5. Clean and free of dust and dirt-This is especially important if the inverter is used in a dusty working environment. Select a Suitable Location.

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(e.g., 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 transistors or IGBT technology in a full bridge configuration. The result is excellent overload capability and the capacity to operate difficult reactive loads.

Connection Method

  1. Attach the ring type connector marked with red to 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.

  1. 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.
  2. When the inverter is not in use, unplug it from the 12V/24V/48V DC outlet to avoid the battery’s discharge.

CAUTION: Before using the inverter, please provide a ground connection wire. On the rear panel of the inverter is a terminal 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 boat’s grounding system.

Battery’s Charge

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.

Inverter’s Working Status

  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 delivers AC power to the outlets.
  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.

  1. 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.
  2. If the AC appliance’s rated power is higher than the inverters rating (or the appliance  draws excessive surge power), the inverter will shut down. The red FAULT indicator will light.
  3. 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.
  4. If a defective battery charge system has caused the battery voltage to rise to a dangerously high level, the inverter will automatically shut down.
  5. 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.
