WARNING
The entire system should be installed by professional and technical personnel.
2. Requirements for professional and technical personnel
Professionally trained；
Familiar with related safety specifications for the electrical system;
Read this manual carefully and master related safety cautions.
3. Professional and technical personnel is allowed to do
Install the inverter to a specified location.

2
Conduct trial operations for the inverter.
Operate and maintain the inverter.
4. Safety cautions before installation
IMPORTANT
When you receive the inverter, check whether there is any damage in
transportation. Contact the transportation company or our company in time for any
problem.
CAUTION
When placing or moving the inverter, follow the instructions in the manual.
When installing the inverter, evaluate whether the operation area exists arc
danger.
The inverter needs to be connected to a battery. The battery's minimum
capacity (Ah) is recommended to be five times the current that equals the
inverter's rated output power divided by the battery's voltage.
WARNING
Keep the inverter out of the reach of children.
This inverter is an off-grid type. It is strictly prohibited to connect the inverter to
the grid. Otherwise, the inverter will be damaged.
This inverter is only allowed for stand-alone operation. It is prohibited to
connect multiple units in parallel or series. Otherwise, the inverter will be
damaged.
5. Safety cautions for mechanical installation
WARNING
Before installation, ensure the inverter has no electrical connection.
Confirm enough heat dissipation space for the inverter before installation. Do not
install the inverter in a harsh environment such as humid, greasy, flammable,
explosive, or dust accumulation.
6. Safety cautions for electrical connection
CAUTION
Check whether wiring connections are tight to avoid the danger of heat
accumulation due to loose connections.
The protective grounding is connected to the ground. The cross-section of the
wire should not be less than 4mm2.
The DC input voltage must strictly follow the parameter table. Too high or too low
DC input voltage will affect the inverter's normal operation and may even damage

3
it.
It is recommended that the connection length between the battery and the
inverter be less than 3 meters. If greater than 3 meters, please reduce the current
density of the connection wire.
A fuse or breaker should be used between battery and Inverter; the fuse or
breaker's rated current should be twice the inverter rated input current.
DO NOT install the inverter close to the flooded lead-acid battery because the
terminals' sparkle may ignite the hydrogen released by the battery.
WARNING
The AC output terminal is only for the load connection. Do NOT connect it to
another power source or utility. Otherwise, the inverter will be damaged. Turn off
the inverter when connecting loads.
Do not connect battery chargers or other similar products to the input terminal of
the inverter. Otherwise, the inverter will be damaged.
7. Safety cautions for controller operation
WARNING
HOT
SURFACE

10. Safety cautions for inverter maintenance
It is recommended to check the inverter with testing equipment to ensure no voltage and current.
When conducting electrical connection and maintenance, post a temporary warning sign or put up
barriers to prevent the unrelated personnel from entering the electrical connection or maintenance
area.
An improper operation of the inverter may cause personal injury or equipment damage.
It is recommended to wear an antistatic wrist strap or avoid unnecessary contact with the circuit
board.

1 Overview
IPT is a new generation of pure sine wave inverter, which can be customized according to customer
needs. Adopting the voltage and current double closed-loop control algorithm brings the inverter a faster
response and a lower THD. The inverter selects key components with a high power density and long
lifespan to provide a stable and reliable power guarantee.
1000W and above IPT products are equipped with two AC outlets. It supports two AC loads
simultaneously (Note: the total load power cannot exceed the rated power). At the same time, users
can choose various human-computer interaction solutions, which is convenient to control real-time
parameters.
The inverter can be widely used in DC to AC areas, such as solar AC power system, vehicle system, RV
power supply, security monitoring system, emergency lighting system, field power system, household
power system, etc. With industrial standard EMC (Electro Magnetic Compatibility) characteristics, the
inverter is also suitable for occasions with high power quality requirements.
Features:
Industrial standard, cost-effective
Customizable input reverse polarity protection and surge current suppression technology
Completely electrically isolated design for input and output
Full digital double closed-loop control
Excellent EMC characteristic, widely applied to higher quality power system
Advanced SPWM technology and pure sine wave output.
Double AC output ports (suitable for 1000W and above) to support two AC loads working at the
same time
Multi AC outlets to meet the users' needs of different countries and regions
High power density and high-quality components to ensure the reliability
Output power factor up to 1
Low loss of zero loads and standby. Low THD (Total Harmonic Distortion). High conversion
efficiency
Extensive input under voltage/over-voltage, output overload/short circuit/overheating Instruction
Air cooling controlled by temperature and load
Remote control by the phone APP and PC software

Configurable output voltage and output frequency①
RS485 com. port②, to support various optional accessories
RJ11 port②to connect a remote switch, convenient to start/stop device and view errors remotely
External switch contact design to allow remote control
EN/IEC62109-1/2, EN61000-6-2/4 and FCC approved
①Related parameters' settings can only be operated through the remote meter, mobile phone
APP, or PC software.
②For inverters with 12V/24V input voltage, the RS485/RJ11 port has NO communication
isolation design. This function (communication isolation design) is just for inverters with 48V
input voltage.

GFCI outlets need to be tested after power-on to ensure proper operation.
Preparation
Connect a circuit breaker and an AC load (it is recommended to use a night light to observe the status
conveniently) to the GFCI outlet. Turn on the inverter after confirming the wiring.
Testing
1) If the red LED is ON solid, it indicates that the GFCI outlet is damaged; please replace a new one.
2) If the LED is green ON after it flashes in red three times, connect the circuit breaker, and the night light
will be turned on. Then, press the "TEST" button to observe the testing status:
① The "TEST" button always pops up, and the night light keeps ON solid. It indicates that the GFCI
wiring is an error; please correct the wrong wiring.
② The "TEST" button goes down, while the "RESET" button pops up. The LED and the night light are
turned off, indicating the GFCI outlet is normal (Note: Press the "RESET" button again to
recover the load output).

The DC input and AC outlets located on different sides
The DC input and AC outlets are located on different sides, such as IPT350-xx, IPT500-xx, IPT1000-xx,
IPT1500-xx, IPT2000-xx, and IPT3000-42. The following takes IPT2000-2x as an example to introduce
the system connection.
The DC input and AC outlets located on the same side
The DC input and AC outlets are located on the same side, such as IPT3000-1x/2x, IPT3000-41,
IPT4000-4x, and IPT5000-42. The following takes IPT3000-1x as an example to introduce the system
connection.
CAUTION
It is recommended to directly connect the inverter DC input terminal to the battery
terminal. DO NOT connect it to the charge source terminal. Otherwise, the charging
voltage spikes of the charge source may cause over-voltage protection of the
inverter.
