Definition
TIP
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.
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, our local distributor, or our
company 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, salt spray, corrosion,
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 damage it.
3
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.
It is strictly forbidden to connect a transformer or a load with a surge power (VA)
exceeding the overload power at the AC output port. Otherwise, the damage will
be caused to the inverter.
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 cover temperature is very high because of the
accumulated heat; 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 an electric arc, fire, or explosion
Touch the wire end that hasn't been insulation treated and may be 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.
4
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
local distributor or the 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
The IPT series, a high-frequency sine wave inverter, adopts a fully digital intelligent design and
voltage-current dual closed-loop control algorithm. Featured with fast response, high conversion
efficiency, low Total Harmonic Distortion(THD), and high reliability running, the IPT series can be widely
used in the DC-AC off-grid systems (such as vehicle systems, security monitoring systems, emergency
lighting systems, household power systems, field power systems, and other systems requiring higher
power quality).
Features:
Pure sine wave output
Input to output electrical isolation
Output power factor up to 1
Input Protection: Low-voltage, Over-voltage
Output Protection: Overload, Short circuit, Overheating
RS485 com. port to realize remote monitoring①
External switch design, matched with EPEVER products, to expand inverter control function and
reduce power consumption
Diversified AC output sockets
EN/IEC62109-1/2, EN61000-6-2/4, and FCC approved
①For 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.
