Explosion Hazard

• 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 propane tanks.
• Do not use the inverter in an enclosure containing automotive-type, lead-acid batteries. These batteries vent explosive hydrogen gas, which can be ignited by sparks from electrical connections.
• When working on electrical equipment, always ensure someone is nearby to help you in an emergency.
• Do not connect live AC power to the inverter's AC outlets. The inverter will be damaged even if it is switched OFF.
• Do not connect any AC load which has its neutral conductor connected to ground, to the inverter.
• Do not expose the inverter to temperatures exceeding 104°F (40°C).

Do not use inverter with the following equipment:

• Small battery-operated products such as rechargeable flashlights, some rechargeable shavers, and night-lights that are plugged directly into an AC receptacle to recharge.
• 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.
• Connect inverter only to batteries with a 12V DC nominal output. A battery with 6V nominal output will not supply enough voltage and a battery with 24V/48V nominal output will DAMAGE THE INVERTER.

4. Installation Guidelines

Selecting a Suitable Location

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

• Dry: Do not expose to water drip or spray.
• Cool: Operate only in ambient temperatures between 32°F (0°C) and 104°F (40°C). Keep away from furnace heating vents or other heat-producing equipment.
• Well ventilated: Allow at least 2 inches (5cm) clearance above and on all sides of the unit for proper cooling.
• Safe: Do not install inverter in a compartment with batteries or flammable liquids, such as gasoline, or explosive vapors.
• Clean and free of dust and dirt: This is especially important if the inverter is used in a work environment.
• Elevation: The product is installed and used at an altitude of less than 2,000 m.
• Avoid side and top foreign material from falling inside the device.
• Use only sealed lead-acid, flooded, lithium battery, or gel batteries which must be deep cycle.

The product must be installed by qualified electricians. The product must be installed in a dry and well-ventilated area, as close as possible to the battery. A space refrigeration device of at least 10 centimeters should be left.

Using the DC Cable-Ring Terminal

Due to limitations in the common 12V DC outlet in a vehicle or boat, the inverter should only be used to supply AC power to products that require the rated continuous power or less.

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.
2. WARNING: A reverse polarity connection (positive to negative) may damage the inverter. Damage caused by a reverse polarity connection is not covered under warranty.
3. Tighten the nut on each DC terminal by hand until it is snug. Do not over-tighten.

5. Operating the Inverter

The inverter is capable of continuously powering most 230V and 240V AC products that use the rated continuous output power or less. It is a pure sine wave inverter designed to mimic utility power.

The power, or “wattage,” rating of AC products is the average power they use. When many AC products are first switched on, they initially consume more power than their power rating. If this problem occurs when attempting to operate several AC products at the same time, try first switching on the inverter with all AC products switched off, then one by one switch each on, starting with the high surge product first.

Indicators and Controls

• The AC outlets are provided on one end of the inverter. Any combination of 230V/240V AC products with a total continuous power consumption of the continuous power or less may be plugged in.
• The ON/OFF switch enables output AC power at the AC outlets when switched ON.
• The green POWER light indicates AC power is present at the AC outlets and the inverter is operating normally.
• The red FAULT light indicates inverter shutdown caused by low or high voltage, overload, or excessive temperature.
• The yellow Fault light indicates short circuit or overload starting protection.

Inverter Operation Steps

1. When properly connected to a 12V DC outlet or battery, turning the ON/OFF switch ON will illuminate the green POWER light and provide AC power to the outlets.
2. Plug the AC product(s) you wish to operate into the AC outlet(s) and switch them on, one at a time.
3. As the battery capacity is used up, battery voltage begins to fall. When the inverter senses that the voltage at its DC input has dropped to 9.7~10.7V, an audible alarm will sound. This allows time for computers or other sensitive devices to be shut down.
4. If the audible alarm is ignored, the inverter will automatically shut down when the battery voltage drops to 9~10V. This prevents battery damage from excessive discharge. After auto shutdown, the red FAULT light illuminates.
5. On the DC (M8) side, remove the protection cap.
6. Unscrew Positive and Negative DC Input Terminals, connect a battery bank to the terminals, and tighten the terminal screws. Torque: 14(±0.5) N•m. For your safety, it is recommended to use a battery fuse.

AC Priority Switch Function

The AC Priority function allows the inverter to automatically switch between battery (DC) and mains (AC) power. When both AC input and battery input are available, AC input is selected automatically as priority. When AC input is removed, the unit will change to DC input automatically. After the transfer from battery supply to AC utility supply or vice versa, please check if the electronic devices need to be restarted manually.

6. Battery Operating Time

Operating time will vary depending on the charge level of the battery, its capacity, and the power level drawn by the particular AC load.

When using the battery of the vehicle as a power source, it is strongly recommended to start the vehicle every hour or two to recharge the battery before its capacity drops too low. The inverter can operate while the engine is running, but the normal voltage drop that occurs during starting may trigger the inverter's low voltage shutdown feature.

Because the inverter draws less than the no-load current draw with the ON/OFF switch in ON position and with no AC products connected, it has minimal impact on battery operating times.

7. Interference with Electronic Equipment

Generally, most AC products operate with the inverter just as they would with household AC power. Below is information concerning two possible exceptions.

Buzzing Sound in Audio Systems and Radios

Some inexpensive stereo systems, “boom boxes,” and AM-FM radios have inadequate internal power supply filtering and “buzz” slightly when powered by the inverter. Generally, the only solution is an audio product with a higher quality filter.

Television Interference

The inverter is shielded to minimize its interference with TV signal. However, with weak TV signals, interference may be visible in the form of lines scrolling across the screen. The following should minimize or eliminate the problem:

• Use an extension cord to increase the distance between the inverter and the TV, antenna, and cables.
• Adjust the orientation of the inverter, television, antenna, and cables.
• Maximize TV signal strength by using a better antenna and use shielded antenna cable where possible.
• Try a different TV. Different models of televisions vary considerably in their susceptibility to inverter.

8. Troubleshooting

PROBLEM: AC product will not operate

PROBLEM: Inverter will run some small loads, but not large ones

PROBLEM: Battery run time is less than expected
