7. 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. Better to be used 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 5cm clearance above and on all sides of the unit for proper cooling.
• Safe. Do not install inverter in a compartment with non-sealed 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.

The function of inverter is to convert the DC12V, 24V, 48V voltage into AC110V, 120V, 220V, 230V, 240V. For connecting the inverter with a battery, you need to:

1. Make a visual inspection to ensure no visible damage has been caused by shipping before connecting. Then make sure that the inverter is Switched Off.
2. When inverter connect to the battery, make sure that the battery voltage is consistent with the inverter reference voltage.
3. Connect the red cable of the inverter to the Positive pole (+) of battery, Connect the black cable of the inverter to the Negative pole (-) of battery. Do not connect the cable reversely, otherwise the inverter fuse will be burnt.

CAUTION! A reverse polarity connection (positive to negative) may damage the inverter. Damage caused by a reverse polarity connection is not covered under warranty.

4. Tighten the nut on each DC terminal by hand until it is snug. If DC terminal is big, please use tools to tight up the screw.
5. Turn on the inverter power switch, if green indicator light is on, indicating that the inverter is working properly.
6. Please connect the loads to the AC output of inverter, please do not overload. In the case of overloading, the inverter will send alarm and stop working. To restart the inverter, please firstly switch OFF the inverter for 5 seconds, reduce the load, then switch ON again.

8. Precautions

The inverters are designed, manufactured and tested as per safety standards. However, as an electrical and electric product, it must be installed, operated and maintained strictly according to the related safety instructions as follows:

1. Reverse connection between the inverter and battery is strictly prohibited, it will burn the fuse of the inverter.
2. Please double check if the voltage of the battery matches the inverter input DC voltage, mismatch connection between the inverter and battery can cause serious damage.
3. Double check if the connections are correct, make sure the connections are tight and firm.
4. Do not extend the inverter power cable.
5. When the inverter is not in use please switch off and unplug it from the 12V/24V/48V DC outlet to prevent slight discharge of the battery.
6. Avoid contacting of any foreign objects or fluid. Do not touch the inverter with wet hand. Keep the product away from children. Avoid using it in damp, dusty, high temperature area. Do not use this product in flammable and combustible area.
7. Install the product in well ventilated place, avoid using this product on or nearby hot objects such as electrical heater etc. Do not cover the inverter, avoid direct sun shine, moisture and water.
8. This inverter can NOT be parallel connected.
9. It’s strictly prohibited to connect this product to the city grid.
10. Do not try to repair the inverter, once the inverter is opened, warranty void.

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.

9. Using the Inverter

Using the DC Cable Clips or Direct Connect Cables
By directly connecting the inverter to a DC12V 24V 48V battery with the DC Cable-Chips, you can operate products with power requirements up to the rated continuous output power.
The power, or ‘wattage’, rating of AC products is average power they use. When many AC products are first switched on, they initially consume more power than their power rating.
For loading such as motor rectifier, there is a surge current when starting. Please note the starting current can’t exceed the maximum rated current. ( The starting current of motor may be 7-12 times the rated current. )

CAUTION! Modified sine wave inverter can’t take above mentioned load.

It’s normal that the output voltage drops when a heavy load is present. You must take action in case of below condition.
When the battery DC voltage is reduced below

Solution:

• increase the battery capacity.
• reduce the load on inverter.

When output AC voltage drops below acceptable levels 210V AC (220V 230V 240V inverter), 105V AC (110V 120V inverter)

Solution:

• increase the battery capacity.
• reduce the load.

Although the inverter can supply momentary surge power, occasionally some products rated less than the rated continuous output power may exceed its surge capabilities and trigger its safety overload shut down feature. 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.

Inverter Operation

1. When correctly connected the inverter to battery, turning the ON/OFF (I/O) switch ON (I), will illuminate the green light and deliver 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 is used up, battery voltage begins to fall. When the inverter senses that the voltage at its DC input has dropped to 10.5±0.5V (12V inverter) or 21±0.5V (24V inverter) or 42±1V (48V inverter) an audible alarm sounds. This allows time for computers or other sensitive devices to be shut down.
4. The inverter keep alarming and will automatically shut down when the battery voltage drops to 9.5±0.5V (12V inverter) or 19±0.5V (24V inverter) or 38±1V (48V inverter). This prevents battery damage from excessive discharge. After auto shut down, the red FAULT light illuminates.

IMPORTANT: Vehicle batteries are designed to provide brief periods of very high current needed for engine starting. They are not intended for constant deep discharge. Regularly operating the inverter from a vehicle battery until the low voltage alarm sounds will shorten the life of the battery. Consider connecting the inverter to a separate deep discharge type battery if you will be frequently running electrical products for extended period of time.

5. If an AC product rated higher than the rated continuous power (or which draws excessive surge power) is connected, the inverter will shut down. The red FAULT light will turn on.
6. If the inverter exceeds a safe operating temperature, due to insufficient ventilation or a high temperature environment, it will automatically shutdown. The red led light will turn on and the audio warning will sound.
7. Should a defective battery charging system causes the battery voltage to rise to dangerously high levels, the inverter automatically shuts down.

CAUTION! Although the inverter incorporates protection against over- voltage, it may still be damaged if the input voltage exceeds 16.2 VDC (12V inverter) or 31V DC (24V inverter) or 63V DC (48V inverter).

8. The cooling fan is designed to operate only when the temperature is higher than 40°C.
9. In the event of an overload, low battery voltage or overheating, the inverter will automatically shut down.
10. The inverter will need to be manually reset when shut down by overload.

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 a vehicle as a power source, it is strongly recommended to start the vehicle every hour or two to charge 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 inverters low voltage shutdown feature.

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

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 audio product with a higher quality filter.

Television Interference

The inverter is shielded to minimize its interference with TV signals. 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 interference.

10. Trouble shooting

If you have any problem with your inverter, the first thing you should do is to disconnect any load from it, switch the inverter off and disconnect it from the battery. The summary table below should help you to find the cause of the problem.
