Please read the literature accompanying the following symbols.

Symbols

Definition

Tips:

Indicates any practical advice for reference

IMPORTANT: Indicates a critical tip during the operation, if ignored, may cause the

device to run in error.

CAUTION: Indicates potential hazards. If not avoided, it may cause the device to be

damaged.

WARNING: Indicates the danger of electric shock. If not avoided, it would cause

casualties.

WARNING HOT SURFACE: Indicates the risk of high temperature, if not avoided,

would cause scalds.

Read the user manual carefully before any operation.

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.

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

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

When the inverter is working, the shell will generate much heat, and the temperature

is very high; please do not touch it.

CAUTION

When the inverter is running, please do not open the cabinet.

WARNING

The inverter's AC output is of high voltage, do not touch the wiring connection to

avoid electric shock.

8. Dangerous operations which would cause electric arc, fire or explosion

Touch the wire end that hasn't been insulation treated and maybe electriferous.

Touch the wiring copper row, terminals, or internal inverter modules that may be electriferous.

The connection of the power cable is loose.

Screw or other spare parts inadvertently falls into the inverter.

Improper operations by untrained non-professional or technical personnel.

WARNING

Once an accident occurs, it must be handled by professional and technical

personnel. Improper operations would cause more serious accidents.

9. Safety cautions for stopping the inverter

The internal conductive modules could be touched after the inverter stopped running for five

minutes.

The inverter is allowed to restart after removing the faults, which affects the safety performance.

There are no serviceable parts inside. If any maintenance service is required, please contact our

service personnel.

WARNING

Do NOT touch or open the shell after the inverter is powered off within ten minutes.

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.
