INSTALLATION

Ensure there is enough space for the installation, and the location should meet the following requirements:

  1. Water should not access the inverter.
  2. The ambient temperature should be 32~104°F, and the preferred temperature is 50-77°F. The lower the better in this range of ambient temperature.
  3. Allow for 12 inches around the inverter for adequate air flow.
  4. Do not mount the inverter upside down.
  5. We recommend mounting the inverter on something stable to prevent it from bouncing. Impact shock could result in damage to your unit. Be sure to use all four mounting screws for optimal stability. Mount in a location that can support the weight of the inverter.
  6. Prevent objects from blocking the vents and provide enough air to circulate.
  7. Do not install the inverter in an environment with high dust, sawdust residue, or other particles that may get sucked into the inverter increasing internal temperature.
  8. There will be some electrical arcing or spark when the inverter connects with the battery. Combustible materials such as gasoline, alcohol, etc. should not be around the inverter.

BATTERY

  1. The battery is designed to supply the inverter with DC input voltage and the rated voltage should be in accordance with the rated input voltage of the inverter. Any voltage exceeding the range of the input voltage of the inverter will cause the inverter to go into overload and could possibly damage the inverter. The battery should supply enough current for the load. The load is the amp or watt rating of the equipment being powered by the inverter. A small-capacity battery cannot provide enough power for large electrical equipment. In this case, the battery will cause the inverter to  go under-voltage protection because of the load put on the battery. A simple way to calculate the load or amps required from your battery is to divide watts of equipment by battery voltage.  Due to the consumption of the inverter itself, the actual current will be about 10% more. For example, the voltage of the lead-acid battery is 12VDC, and the load of the equipment is 1000W, therefore, the actual current needed from the battery is about 1000W / 12V = 83.3 amps per hour. Add 10% for efficiency loss and you get 83.3 * 1.10% = 91.6 amp per hour needed. If you don’t know the wattage of your equipment, you can figure the wattage by multiplying AC amps by AC voltage. For example, a refrigerator is 8 AC amps * 120 Volts AC = 960 watts. Remember, all equipment has a  start-up requirement of 3-5x its running wattage. In this example, 960 watts * 3 = 2880 watts needed from the inverter so don’t size your inverter too small.
  2. Battery operating time depends on battery capacity and load. The formula for operating time is: battery capacity divided by the value of the load divided by battery voltage times 1.10%. For example, using the numbers from above, the battery specification is 12V, 200Ah capacity and the load is 1000W. Take battery capacity 200Ah / 91.6 amps = 2.18 hours of run time if you fully deplete the battery. This is NOT recommended. Deep cycle batteries last longer when they are only depleted to 50% of capacity.

CONNECTION

  1. Grounding
    The power inverter has a terminal on the rear panel marked ” Grounding “or “≡”.
    This is used to connect the chassis of the power inverter to the ground. The ground terminal has already been connected to the ground wire of the AC output receptacle through the inverter.  The ground terminal must be connected to the ground wire, which will vary depending on where the power inverter is installed. In a vehicle, connect the ground terminal to the chassis of the vehicle. In a boat, connect it to the boat’s ground system. In a fixed location, connect the ground terminal to the earth.
  2. Battery terminals
    Before you connect the battery cables, make sure the power switch is in the off position. Connect Red (+) battery cable to Red (+) inverter terminal. Connect Black (-) battery cable to Black (-)  inverter terminal. Connect Red (+) battery cable to Red (+) battery terminal. Connect Black (-) battery cable to Black (-) battery terminal. Alligator clamp cables may be used but only to connect to the battery.
    Do not use clamps on inverter terminals. Alligator clamps are not a permanent solution. You may see a spark during the connection. Do not reverse the polarity.
    This may damage the inverter and void warranty.
  3. If connecting to a breaker panel does NOT neutral ground bond the panel.

USING THE POWER INVERTER

  1. Check the output voltage and capacity of the battery. The battery (s) should match the voltage of the inverter and have enough capacity for the load.
  2. Connect your inverter to your battery bank and do not to reverse the polarities of the connection.
  3. Press the power switch button on your inverter for .5 seconds and a green LED will light up indicating that the inverter is on.
  4. Before plugging anything into your inverter, make sure the appliance you are trying to power is shut OFF, then plug it into the AC outlet of your inverter and power on your appliance.
  5. Once finished using the inverter, turn off your electrical appliance and the inverter. The indicator lights should be off.
  6. The cooling fans inside the inverter do not work until the case temperature reaches approximately 104°F.
  7. If you do not plan to use the inverter for a long period of time, disconnect it from your battery bank. Leaving the inverter on and connected for long periods of time may harm the equipment and over-discharge the battery.
  8. The USB port on this unit can provide a stable line of 5V DC current. The maximum current is 1000 mA. Be sure to double-check your device to make sure it doesn’t exceed these requirements.

SOFT START TECHNOLOGY

The soft-start technology built into this inverter protects the unit from delivering too much AC power at once by gradually increasing the AC voltage pushed out. To make sure that you are utilizing this feature, turn on the appliance being used before turning on the inverter. This is especially necessary for equipment that has an inductive load or electrical motor.

OUTPUT VOLTAGE & WAVEFORM

The electrical waveform output of this inverter is a pure sine wave, which has the same quality as utility and/or domestic power. This type of waveform is suitable for most electrical devices, appliances, and tools. This pure sine wave unit provides more capabilities than modified sine wave inverters because it is a cleaner form of power. The pure sine wave also effectively reduces the noise produced while using appliances.

PROTECTIONS IN THE INVERTER

  1. Input under-voltage alarm: When the input DC voltage is lower than 9.8V (19.6V/39.2V), the buzzer will whistle intermittently to remind that the inverter will go into the under-voltage protection.
  2. Under-voltage protection: The inverter will automatically shut down when the input DC voltage is lower than 9.5V(19V/38V). The buzzer will whistle continuously and the green light is off, red light is on. Please turn off the inverter and use it after recharging the battery.
  3. Overvoltage protection: The inverter will automatically shut down when the input DC voltage is higher than 16V(32V/62V). The buzzer will whistle continuously and the green light is off, red light is on. Please turn off the inverter and adjust the input voltage to the admissible range.
  4. Overload protection: The inverter will automatically shut down when the load is higher than the rated power. The buzzer will whistle continuously. Turn off the inverter and resume to normal operation after taking away the excessive load.
  5. Short-circuit protection: The AC output will automatically shut down when short-circuited. It will automatically reset after the problem is solved.
  6. Thermal protection: The unit will get hot during operation. If the temperature is higher than 149°F, the inverter will automatically shut down. Then the buzzer will whistle continuously and the green light is off, red light is on. Please turn off the inverter, and continue using it after the temperature goes back to normal naturally. Meanwhile find out the factors causing the fault, such as ventilation, ambient temperature, vent, load power, etc. It can avoid similar things from happening again.

**NOTE** The numbers in the parenthesis are for 24V and 48V models. In the case of over voltage, under voltage, and thermal protection, the inverter will shut down. When the inverter is in the  OFF position, the inverter doesn’t consume battery current.

HI-POT TESTING OF DC to AC Inverter
Most of our AC inverters are Listed by Intertek to conform to UL 458 standards. One of the requirements of UL 458 is that all AC inverters pass a High Voltage Dielectric Withstand Test, commonly called the Hi-Pot Test. The voltage applied to the control is usually equal to 1,000 volts, plus two times the line voltage rating of the inverter.
Therefore, the standard hi-pot voltage for a 115 VAC inverter is 1,250 VAC. For 230 VAC or dual voltage inverters, the hi-pot voltage is 1,500 VAC. This AIMS Power inverter is hi-pot tested before it leaves the factory, with a UL Certified hi-pot tester, set to the voltages shown above.
