Our power inverters are equipped with numerous protection features to guarantee safe and trouble-free
operation:
Low Battery Alarm
Alerts you if the battery has become discharged to 10.5V
or lower.
Low Battery Voltage Shutdown
Shuts the inverter down automatically if the battery
voltage drops below 9.5 volts. This feature protects the
battery from being completely discharged.
High Battery Voltage Shutdown
Shuts the inverter down automatically if the input
voltage rises to 15.5 volts or more.
Over Load Shutdown
Shuts the inverter down automatically if the loads
connected to the inverter exceed the inverter’s
operating limits
Over Thermal Shutdown
Shuts the inverter down automatically if its internal
temperature rises above an unacceptable level.
Output Short Circuit Shutdown
Shuts the inverter down automatically if a short circuit is
detected in the circuitry connected to the inverter’s
output
Reverse Polarity Protection
If wrong polarity connection, the internal fuse shall blow
out.
Earth Fault Protection
The inverter complies with the standard current leakage
allowance. When large current leakage to earth terminal
occurs, the protection circuit activated and shut down
the inverter, which prevent electric shock to human.
Turn off the inverter, unplug the fault AC appliances and
then turn ON is the way to restart it.
Notes: All protection is automatically recovered. To protect the battery, if the unit needs to be restarted
after lower voltage protection, the voltage of DC input factory setting: pure sine wave inverter is 12.6 V
3.
Protection Features

The power inverter must only be installed in a location that is:
Dry:
The inverter must be installed in a dry location not subject to moisture especially rain, spray, or splashing
bilge water.
Cool:
The inverter should not be exposed to metal fillings or any other form of contamination.
Ventilated:
The ambient air temperature should be between 0 - 40°C for best performance
Safe:
Ventilation openings on the inverter must not be obstructed. If the inverter is mounted in a tight fitting
compartment, the compartment must be ventilated with cut-outs to prevent the inverter from
overheating.
Close to battery:
The inverter is not ignition-protected equipment, so it cannot be installed in areas containing gasoline
tanks or fittings which require ignition –protected equipment. We recommend that it is safest not to
install any kind of electrical equipment including the inverter in these areas.
Protected from battery gases:
The inverter should be installed as close as possible to the batteries, but not in the same compartment to
prevent corrosion. Avoid excessive cable lengths and use the recommended wire sizes. We recommend
that installing with battery cables sized to achieve less that 3% voltage drop on battery cables under full
load. This will maximize the performance of the inverter.

permanent damage to the inverter
8. Chassis ground screw grounding the earth by use wire.
9. High –Speed Cooling fan must not be obstructed for the proper operation of the inverter. When the
inverter is mounted, then ventilation opening on the DC panel must not point up or down.
10. DC cable with ring, please you can connect the ring in red cable to red terminal on inverter and the
ring in another side to battery. Do same way in black cable.
11. DC cable with clip, you can use it connect the battery and inverter by connecting the clips in cable to
battery, and the ring in another side to inverter.
Warning: Symptoms of low battery power can result from cables that are either excessively long or an
insufficient gauge. Substantial power loss and reduced battery operating time results from inverters
installed with cables that are not able to supply full power.
Notes: The installer/operator should be especially aware of the requirements to maintain secure, tight,
water-resistant electrical connections and to provide for strain relief for DC cables and appliances wiring.
Cable insulation must be the appropriate type for the environment.
The AC output waveform of the VSP series inverter output waveform is “pure sine wave”.

The inverter’s Output Waveform

INTERFERENCE WITH SOME EQUIPMENT
Buzz in Audio Equipment
Some inexpensive stereo systems may emit a buzzing noise from their loudspeakers when operated from
the inverter. This occurs because the power supply in the audio System does not adequately filter the
modified sine wave produced by the inverter.
The only solution is to use a sound system that has a high quality power supply.
Television Reception
When the inverter is operating, it can interfere with television reception on some channels. If interference
occurs, try the following:
1. Make sure that the chassis ground screw on the rear of the inverter is solidly connected to the ground
system of your vehicle or home.
2. Make sure that the television antenna provides an adequate (“snow-free”) signal and that you are using
good quality cable between the antenna and the television.
3. Keep the cables between the battery and the inverter as short as possible, and twist them together
with two to three twists per foot. (this minimizes radiated interference from the cables.)
4. Move the television as far away from the inverter as possible.
5. Do not operate high power loads with the inverter which the television is on.
Battery Requirements
Battery type and battery size strongly affect the performance of the power inverter. Therefore, you need
to identify the type of loads your inverter will be powering and how much you will beusing them between
charges. To determine the minimum battery size that you need to operate appliances, follow these steps:
1. Determine the wattage of each appliance and/or tool you will need to simultaneously operate from the
inverter. To do this, read the labels on the requirement to be operated. Usually, power consumption is
shown in watts. If it is shown in amps, multiply by 230V to determine the wattage.
2. Estimate the number of hours the equipment will be in use between battery recharges.
3. Determine the total watt-hours of energy use, the total running time and the average power
consumption power (in watts) by 10 if 12V system, by 20. If 24V system, by 40 if 48V system.
To calculate the approximate power in amps a 24 volt battery bank has to supply you need to know the
current, or amps required for powering the continuous AC load. A shortcut method is to divide the
continuous AC load. A shortcut method is to divide the continuous AC load wattage by 20.
For example, the continuous AC load is 2000 watts, the current (amps) is: 2000/20 or 100amps at 24V DC.
Add to the load any DC appliances that may be powered by the battery bank.
Notes: Some appliances required high surge power to start, then consumer less power. And some
appliances are not operating for long periods of time. For example, a typical home-use coffee maker
draws 500watts during its brew time of 5 minutes, but it maintains the temperature of the pot at about
100watts. Typical use of a microwave is only a few minutes, sometimes at lower power; some exceptions
to brief operating times are lamps, TVs and computers.
Important: The power inverter must be connected only to batteries with a normal output voltage of 12V
when you use a 12V inverter. The unit will not operate from a 6V battery, and will sustain permanent
damage if connected to a 24V battery.
Caution: Loosen connectors may cause overheated wires and melted insulation. Check to make sure you
have not reversed the polarity. Reverse polarity connection will result in a blown fuse and may cause
permanent damage to the inverter.
The calculation of the Battery’s Back Up Time
The battery’s back up depends on the battery capacity (Ah) and your appliances power (Watt)
The method to calculate the backup time:
Battery capacity (Ah) * Input voltage (Volt)/Loads power (Watt)
For example:
Battery capacity = 150Ah
Input voltage = 12Volt
Loading power = 600Watt
So:
(150Ah*12V)/600Watt = 3 Hours
Note: the time calculated by this way is a theory value; the actual using time may short than this value
Recharging Batteries
When possible, recharge your batteries when they about 50% discharged or earlier. This gives the
batteries a much longer life cycle than recharging when they are more deeply discharged.
Our inverter has a battery low voltage shutdown around 10V DC. With moderate to heavy loads, this will
protect against over-discharging the battery. If the inverter is running only light loads it is advisable to
recharge before the inverter low voltage shutdown point is reached.

Choose the Battery

Batteries Wiring
1. SERIES WIRING
Wiring batteries in a series increases the total battery bank output voltage. A series connection combines
each battery in a string until the voltage matches the inverter’s DC requirement. Even though there are
multiple batteries, the capacity remains the same. In the example below (Figure 4), two 6V DC/200Ah
batteries are combined into a single string-resulting in a 12V DC / 200Ah bank.
12V battery bank (total capacity = 200 Ah)
Figure 4, Series Battery Wiring
2. PARALLEL WIRING
Wiring the batteries in parallel increases the total run time the batteries can operate the AC loads. A
parallel connection combines overall battery capacity by the number of batteries in the string. Even
though there are multiple batteries, the voltage remains the same. In the example below (Figure 5), four
12V DC/100Ah batteries are combined into a single 12V DC/400AH battery bank.
12V battery bank (total capacity = 400 Ah)
Figure 5, Parallel Battery Wiring
2. SERIES –PARALLEL WIRING
A Series-parallel configuration increases both voltage (to match the inverter’s DC requirements) and
capacity (to increase run time for operating the loads) using smaller, lower voltage batteries. In the
example below (Figure 6), four 6V DC/200Ah batteries are combined into two strings resulting in a 12V
DC/400Ah battery bank.
12V battery bank (total capacity = 400 Ah)
Figure 6, Series-Parallel Battery Wiring
Best use of battery Power
Make sure any appliances are energy efficient and turned off after use. Use Compact Florescent Lamps.
Wherever possible, charge with solar panels or wind generators. Do not allow lead acid batteries to
remain discharged for long periods of time, they lose capacity (amps hours).
Mounting the Inverter
Warning: Keeping ventilation when using batteries. Batteries may generate flammable gas during
charging or discharging.
The inverter (1000W to 3000W models) has four slots in its mounting bracket that allow the unit to be
fastened against a bulkhead, floor, wall or other flat surface. Ideally, the mounting surface should be cool
to the touch.
It is more electrically efficient to use longer AC wiring than DC wiring, so install the inverter as close as
possible to the 12/24/48V DC power source (Battery).
8.
Mounting and Connecting the Inverter

The inverter can be operated in any position, however, if it is to be mounted on a wall, mount it
horizontally (Figure 7) so that indicators, switches, outlets and terminal blocks located on the front panel
are visible and accessible. If inverter is to be installed in a moving vehicle, we strongly recommend that
the inverter be shock-mounted either on the floor (in a clear, safe area) or on a secure flat surface.
Figure 7
System Connection
When you connect the battery with inverter, please remember to connect the correct volts (e.g. 12V
inverter connect with 12V batteries.
The inverter will provide you 230V AC when powered by a 12V DC source. This manual does not describe
all of the possible types of battery configurations, battery charging configurations and battery isolation
configurations. The figure 8 as below show the typical connection.
Figure 8
Note: For safety concern, you can connect a DC-rated fuse or a DC-rated circuit breakers on the positive
cable line in your power system, following these recommendations when you purchasing fuses or circuit
breakers.
Select a fuse or circuit breaker with a proper rating (e.g.: 1000W advice 150A DC, 1500W advice 200A DC)
Determine the short-circuit current rating of the battery and choose a battery fuses that withstand the
short circuit current that may be generated by the battery.
Connection and Installation Steps
1. Check to be sure the inverter’s power switch is turned off and that no flammable fumes are present.
2. Identify the positive (+) and negative (-) battery terminals.
3. Install a fuse holder or breaker close to the positive (+) terminal of the battery.
4. Connect a length of wire on one side of the fuse holder or circuit breaker. Connect the other end of the
wire to the positive (+) terminal of the inverter.
5. Connect a length of wire between the inverter’s negative (-) terminal and the battery’s negative (-)
terminal.
6. Connect a short length of wire to the other terminal of the fuse holder or circuit breaker. Mark it
“positive” or “+”.
7. Connect the free end of the fuse or breaker wire to the positive terminal of the battery.
8. Insert a suitable fuse in the fuse holder.
9. Check to be sure that all connections between battery clips, terminals and fuses are secure and tight.
Notes: Sparking is normal for the first connection.
Make sure you have good secure connections - Do not over tighten.
1. When you have confirmed that the AC appliances to be operated is turned off, plug an appliance cord
into the AC outlet on the front panel of the inverter.
2. Turn ON the inverter.
3. Turn the appliance on.
4. Plug in additional appliances and turn them on.
Notes:
1. Plug the cord from the AC appliances you wish to operate into the AC receptacle. When turn ON the
inverter. The Red and Green LED both lit for 3 - 5seconds then red LED not lit, green LED indicator lights
to indicate that the inverter is functioning. Make sure the combined load requirement of your equipment
does not exceed inverter’s output rating.
2. Turn OFF the inverter. The over load LED may briefly “blink” and the audible alarm may also sound a
short “Chirp”. This is normal. This same alarm may also sound when the inverter being connected to or
disconnect from the battery.
9.
Operating the AC Appliances

3. When using an extension cord from the inverter to an appliance the extension cord should not be
longer than 15 meters.
4. When you plan to operate more appliances, please make sure plug and switch ON the biggest one first
and then smaller one.
Caution: The inverter is engineered to be connected directly to standard electrical and electronic
equipments. Do not connect the powerinverter to household or RV AC distribution wiring. Do not connect
the power inverter to any AC load circuit in which the neutral conductor is connected to ground (earth)
or to the negative of the battery source.
Warning: Do not connect to AC distribution wiring.
Operating Tips
Rated versus actual current draw of equipment
Most electrical tools, appliances and audio/video equipment have labels that indicate the power
consumption in amps or watts.
Be sure that the power consumption of the item you wish to operate is less than inverter’s rating power.
(if the power consumption is rated in amps, simply multiply by the AC volts (230V) to determine the
wattage). The inverter will shutdown if it is overloaded. The overload must be removed before the
inverter will restart.
Resistive loads are the easiest for the inverter to run. However, larger resistive loads, such as electric
stoves or heaters, usually require more wattage than the inverter can deliver. Inductive loads. Such as
TV’s and stereos, require more current to operate than do resistive loads of the same wattage rating.
Induction motors, as well as some televisions, may require 2 to 6 times their wattage rating to start up.
The most demanding in this category are those that start under load, such as compressors and pumps. To
restart the unit after a shutdown due to overloading, remove the overload if necessary turn the power
switch OFF then ON.
