INTRODUCTION
1.1 What is an Inverter?
Power inverter is an electronic device that convert DC(Direct Current) battery
power to standard AC (Alternating Current) power. DC is the power that is
produced by battery while AC is the standard power needed to run electrical
equipment. A power inverter does the opposite of a rectifier and is used in
places and situations where AC power is not available.
1.2 Pure Sine Wave Inverter 
If you want
to run your equipment exactly to the manufacturer’s specifications, choose a
pure sine wave inverter. With pure sine wave, motor loads start easier and run
cooler. Some equipment only operate properly with pure sine wave inverter,
such as laser printers, variable speed motors and digital clocks.

Connect the inverter to battery or other power sources.
Negative (-) and Positive (+) DC terminals should be kept insulated to protect
from accidental short circuits.
a) Connect the black cable to the black post marked (-) on the back of the
inverter. Connect the other end to the negative terminal on the battery.
b) Connect the red cable to the red post marked (+) on the back of the
inverter. Connect the other end to the positive terminal on the battery.
If you connect the cables to the incorrect terminals, you will reverse the
polarity and damage the inverter.
APROHIBITED REVERSE POLARITY.**
DAMAGE CAUSED BY REV ERSE POLARITY WILL NOT BE COVERED BY WARRANTY.
 Amps x AC voltage = Watts
This formula yields an approximation of the continuous wattage load of that appliance.
The startup load of an appliance is a major factor of whether this inverter can power it. Startup load is momentary. With many appliances, it is approximately twice the continuous load, but some appliance startup loads can be as high as eight times the continuous load.
To determine if an appliance or tool will operate with this inverter, run a test. This inverter will automatically shut down in the event of an output overload, so there is no danger of damaging either the inverter or the equipment. When lit, a red LED indicator and Buzzer signals a fault.
3.2 Configuring the Battery Bank
To determine the minimum battery ampere-hour rating that you will need to operate appliances from the inverter and any DC appliances powered by the battery bank, follow these steps:- List the maximum continuous wattage that the inverter has to supply.
- Estimate the number of hours the appliances will be in use between battery recharges. This will vary depending on appliances. For example, a typical home-use coffee maker draws 500 watts during its brew time of 5 minutes. It maintains the temperature of the pot, requiring 100 watts. Typical use of a microwave oven is only for a few minutes. Some longer operating time appliances are lamps, TVs, computers and refrigerator/freezers.
Determine the total watt-hours of energy needed. This is done by multiplying average power consumption in watts by hours of run time. For example: 500 watts for 10 hours = 5000 watt hours. To get an estimate of the maximum current (in amps) that a battery bank must be capable of delivering to the inverter, divide the load watts by ten. For example a 500 watt appliance load will need 50 amps at 12 volts DC. Using the 500 watts (or 50 amps) for 10 hours example as above, then 50 amps is needed for 10 hours. This provides us with the basic amp-hours (AH) of battery that is required. Ten hours at 50 amps equals 500 amp-hours (AH). There are additional factors that determine actual run time. These include:
- AC appliance load and time in use (basic AH).
- Cable gauge and length (cable losses).
- Charge level of the batteries (between use, chargers have to be able to fully charge the batteries).
- Temperature of the batteries (colder batteries provide fewer amps).
- Age and condition of the batteries (older batteries lose AH capacity).
- Compliance with turning off unnecessary AC loads.
- Use of DC appliances and compliance with turning off unnecessary DC loads.
3.3 Battery Wiring Examples
In renewable energy systems, batteries are connected to each other in one of
three ways:
- Series (voltage increases, amperage stays the same as a single battery)
- parallel (voltage stays the same as a single battery, amperage increases)
- Series/Parallel (both voltage and amperage increase)
Two strings of batteries In series are connected In parallel
The voltage increases to 48V and the amp hours Increase to 400
3.4 Placement of inverter
The location where to install inverter must be:
A. Dry: Do not allow water to drip or splash onto it.
B. Cool: Ambient air temperature should be between 0° C and 40° C – ideally between 15° C and 25°.Do not place the inverter on or near a beating vent or any piece of cquipment which is generating heat above room temperature. Do not place the inverter in direct sunlight unnecessarily.
C. Ventilated: Allow at least one inch of clearance around the unit for air flow. Do not place items on or over the inverter during operation. Make sure that air is allowed to circulate freely around the unit. A fan is helpful in the case where the inverter is operating at maximum
D. Safe: Do not install the inverter in the same compartment as the batteries or in any compartment where flammable liquids or fumes may be or may become present.
E. Dust Do not install the inverter in a dusty environments. The dust can be inhaled into the unit when the cooling fan is working.
F. Close to batteries: excessive cable lengths. Do not install the inverter in the same
3.5 Mounting position of the inverter
The inverter may be mounted horizontally on the top of a horizontal surface or under a horizontal surface. The inverter may be mounted on a vertical surface only horizontally.
3.6 Getting Connected
Follow the connection sequence described below.
Step 1 Ensure that tbe ON/OFF switch on the Inverter is in the OFF position. If the power source is a DC power supply, switch it OFF as well.
Step 2 Connect inverter to power source.
Connect the DC cables to the DC battery terminals on the rear panel of the inverter. The red terminal is positive (+) and the black terminal is negative (-).
Step 3 Connect inverter to appliances.
Make sure the foad power within the rated power of inverter and the start power should not exceed the peak power of the inverter. When having the inverter connected with appliances and a power supply, switch on the inverter and appliances. If you are operating several Ioads from the power inverter, turn them on separately after the inverter has been tumed on. This will ensure that the power inverter does not have to deliver the starting currents for all the loads at once.

automatically turn on to cool the inverter. When inner temperature exceeds
75°C, Buzzer sound 5 times and red light turn on AC output will automatically
shut off.
TROUBLESHOOTING REFERENCE
Acoustics buzzer alarms
When applying the inverter to acoustics devices, some inferior acoustics
devices will buzz, this is because the output wave from the inverter is
modified sine wave inverter.
TV Interference
You can get minimum interference through use of a filter. On some occasions,
when the interference of every weak signals becomes too obvious, you can try
the following:
- Place the inverter far from the TV and TV antenna,
- Try to change the direction of TV signals cable and TV antenna to reduce the interference to minimum.
- Use screen cable antenna of highly quality.
