INTRODUCTION

The VOLTWORKS pure sine power inverter product line is used for backup power. The pure sine product line is ideal for sensitive equipment and provides lean power,  which is more efficient for backup power applications. The power inverter transforms DC (direct current) electricity into AC (alternating current)  power which can be used for running a wide variety of tools and appliances. This inverter is perfect for providing mobile power in cars, boats, and work trucks. The inverter can also be utilized as a backup source of electricity in the event of an electrical failure or for several off-grid applications such as camping or in your RV.
Please read this instruction manual carefully and make sure your inverter is installed properly before using it.

 WARNING AND SAFETY

INVERTER INSTALLATION
Ensure there is enough space for the installation, and the location should be 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. Do not mount the inverter upside down.

4.  Allow 12 inches of space around the inverter to prevent objects from blocking the vents and to provide enough air to circulate.

5. 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.

6.  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.

7. 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 ur mounting screws for optimal stability. Mount in a location that can support the weight of the inverter.

REMOTE CONTROLLER INSTALLATION

1. Fix the remote box on a flat surface where a hole should be made, and use 2 screws to fix it through the two mounting holes on the remote controller.
2. Or fix the remote on a standard 86X86mm(3.39×3.39 inch) power socket;
3. Connect the inverter and remote controller by wire before mounting.
   Remark : Without a remote controller, you can turn on the inverter by the switch on the inverter too.

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.  no 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 into under- voltage protection because of the load put n 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%. 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  3.3 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 round. 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 erminal 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 earth. The ground wire must be 14AWG (2.08mm 2 )or larger, and make sure the connections are well.

2.  Battery Connection:
   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 lack (-) battery cable to Black (-) inverter terminal. Connect Red (+) battery cable to Red (+) battery terminal. Connect Black (-) battery cable to Black (-) battery erminal. 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  olution. You may see a spark during the connection. Do not reverse the polarity. This may damage the inverter and void warranty.

Notice:

1. Please do all the safety precautions before connecting, and then check whether the battery voltage complies with the input voltage of the inverter.
2. The cables must be big enough to bear current, or else the inverter can not power up a big load because of voltage reduction caused by the small cross-sectional wire. Refer to the below table to choose cables accordingly.

NOTICE:

1. The above table is only for your reference. In practice, the thick wire can be replaced by two thinner parallel wires if only the total section acreage of the wire meets the requirements.
2. With high current, the input DC cables may produce voltage drop, therefore, the operating voltage should be subject to the value on the terminals. If the voltage drop is too large, it will increase the acreage of the section or reduce the length of the lead. The cable length should be less than 1 meter.
3. Connect the positive wire from the battery positive to the inverter positive terminal(+red), and the negative wire from the battery negative to the inverter negative terminal (-black)  and fix them tightly.

Warnings:

1. Please wear an eye patch and work clothes when working around the battery to avoid the acid and corrosive objects harm your eyes and skin.

2. Prepare enough water and soap. In case the acid materials contact eyes or skin, clean it by soap and water as soon as possible. If the acid materials spay to your
   eyes accidentally, clean it with cold water immediately and then sent to the hospital.

3.  Do not put any combustible material in the location of installation for spark will result when it is connected to the battery.

4.  Keep well ventilated. The battery may produce a little inflammable gas while it is working, so keep it away from the inverter and it is better to install them in different spaces.

5.  Fix the connecting wires tightly, or it will result in voltage over-reduced or wire over-heated.

6. Reverse connection of the polarities or the short circuit will burn the fuse or result in the permanence damage of the internal elements of the inverter.

7. Take away the metal accouterments such as a ring or watch while installing to avoid the short circuit.

8. Although there is over-voltage protection, it may also cause damage of the inverter if the input voltage is too high.

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. See Section E for more information.
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 0.5 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 dual USB ports on this unit can provide a stable line of 5V DC current. The maximum current is 2400 mA each. Be sure to double-check your device to makesure it doesn’t exceed these requirements.
9. .Each outlet of the inverter has a given rating current from the manufacturer. It shall not exceed this value during use. Otherwise, the socket may be damaged by overheating and may cause an electric shock. The maximum output power of a single socket is shown in the following table:

AC output socket| AC  voltage| Max current for

B

| 220~240VAC| 13A| 2500W

C

| 220~240VAC| 10A| 2000W

Connection of big load
For the appliances with a load more than the limit of the AC socket, please connect to the Hardwire Terminals(if have), make sure the ground terminal of the inverter is connected with the ground terminal of the appliance.

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.  o 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 an 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.

 LCD Display

While the inverter is working, the LCD display will show Battery Status Level, Pure Sine Wave Symbol, Input Voltage, Output Voltage, current, etc. Once the inverter is on protection mode, the following codes will be shown:

1. LO: Low voltage protection
2. HI: High voltage protection
3. OL: Overload or short-circuit protection
4. OH: overheat protection.

PROTECTIONS IN THE INVERTER

1.  Input under-voltage alarm: When the input DC voltage is lower than 9.8V (19.6V), 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). The buzzer will whistle continuously and the green light is off, the 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). The buzzer will whistle continuously and the green light is off, the 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  ff the inverter and resume normal operation after taking away the excessive load
5.  Short-circuit protection: The AC output will be 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 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.
