I-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.

3. HOW TO USE INVERTER
3.1 Load consideration
When an appliance with motor starts, it requires a momentary surge of power. This surge of power
is the “start load”or “peak load”. Once started, the appliance require less power to continue to
operate. This is known as the “continuous load”. It is important to know the starting loads of the
appliance that are to be powered by the inverter. Appliance power is rated in watts. This
information is usually stamped or printed on most appliances and equipment. In some cases, a tool
will be rated in amperes. To convert from amps to watts, multiply:
Amps×AC voltage=Watts
The startup load of an appliance is a major factor of whether this inverter can power it. Startup
load is momentary. With many appliance, it is approximately twice the continuous load, but some
appliance start up 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 appliance
from the inverter and any DC appliance power by the battery bank..
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)
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℃and 40℃- idea11y between 15℃and
25℃.Do not place the inverter on or near a heating vent or any piece of equipment 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. C1ose to batteries: Avoid excessive cable lengths. Do not install the inverter in the same

6
compartment as batteries.
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 vertica1 surface only horizontally
3.6 Getting Connected
Follow the connection sequence described below.
Step1 Ensure that the 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.
Step2 Connect inverter to power source.
Connect the DC cables to the DC battery terminals on the rear pane1 of the inverter. The red
termina1 is positive(十) and the black terminal is negative(-).
Step3 Connect inverter to appliances.
Make sure the1oad 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 loads from the power
inverter, tum them on separately after the inverter has been turned on. This will ensure that the
power inverter does not have to deliver the starting currents for all the loads at once.
4. IMPORTANT SAFETY INSTRUCTIONS
Incorrect installation and misuse of the inverter may result in danger to the user or hazardous
conditions.
1. Do not attempt to connect the any other power source, including anyAC power source.
2. Make sure the opening to the ventilation fan and vent holes are not blocked.
3. Avoid pulling on the cords and cables. Always grip plugs firmly when unplugging from power
source and when disconnecting cables.
4. To avoid electrical hazard, be sure to unplug the inverter from its external power source before
inserting the AC plug.

5.PROTECTION FEATURE
Inverter is equipped with numerous protection features to ensure safe operations.
Input Low Voltage Protection:
A: When battery voltage is below 10.5±0.2V, Buzzer sound 2 times, which indicates DC power
supply voltage is descending and batteries need to recharge.
B: When input voltage reach 10±0.2V, Buzzer sound 3 times and red light turn on. AC output
will be automatically shut off.
Input Over Voltage Protection
When input voltage reach 15.5±0.5V, Buzzer sound 4 times and red light turn on, the AC
output will be automatically shut off.
Short Circuit Protection
When short circuits occur, Buzzer sound 11 times and red light turn on, output will be shut off.
Overload Protection
When overload occur, Buzzer constantly sound and red light turn on, output will be shut off.
Reverse polarity protection: Fuse or MOSFET
a. Via Fuse: When battery terminals are reverse connected, fuse will be burned to protect
appliance.
b. Via MOSFET(Optional): When battery terminals are reverse connected, the inverter won’t work
until correct connect.
Over Temperature Protection
When heat sink temperature exceed 45℃，the inner cooling fan will automatically turn on to cool
the inverter. When inner temperature exceed 75℃，Buzzer sound 5 times and red light turn on,

8
AC output will automatically shut off.
6．TROUBLESHOOTING REFERENCE
Acoustics buzzer alarms
When applying the inverter to acoustics device, some inferior acoustics device will buzz, this is
because the output wave from the inverter is modified sine wave inverter.
Note: * When 190%≤Load≤200%,limit current of AC output, that’s to say AC Output Voltage
decreasing, output shut down, delay 60s to restart automatically, once ten consecutive restart
automatically, then you have to start the inverter by manual.
7. Maintenance
To keep your inverter operating properly, there is very little maintenance required. You should
clean the exterior periodically with a dry cloth to prevent accumulation of dust and dirt. At the
same
tome, tighten the screws on the DC input terminals.
II- MPS SYSTEM
8. GENERAL INFORMATIONS
Inverter with MPS (Mains Priority System) function is a combination of an inverter and AC Auto
transfer switch into one complete system with a peak dc to ac conversion
advanced system in the market today.
MPS System : it also called the AC priority .the AC power will be direct to
the loads through bypass ways. For example when connecting to the mains on a motorhome service
area, the converter automatically selects the 230V, thus stopping the use of 12V batteries. It is not
necessary to disconnect the batteries in order to use the mains.
MPS (Mains priority system) Mode: the AC input of the inverter is continually monitored.
Whenever AC power falls ,the inverter automatically transfers back to the inverter mode with minimum
power interruption to your appliances as long as the inverter is turned on. The transfer time is usually
fast enough to keep your equipment (including computers) powered up. The time will be less than 16
milliseconds
