WARNING
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
5. Safety Cautions for Mechanical Installation
-2-
When you receive the inverter, check whether there is any damage in
transportation. Contact the transportation company, our local distrib-
utor, or our company for any problem.
•
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.
•
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.
IMPORTANT
CAUTION
WARNING
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.
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.
7. Safety Cautions for Controller Operation
-3-
When the inverter is working, the cover temperature is very high
because of the accumulated heat; please do not touch it.
When the inverter is running, please do not open the cabinet.
The inverter's AC output is of high voltage, do not touch the wiring
connection to avoid electric shock.
CAUTION
WARNING HOT
SURFACE
WARNING
•
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.
•
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.
•
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.
CAUTION
WARNING
• 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.
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.
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.

WARNING
Once an accident occurs, it must be handled by professional and
technical personnel. Improper operations would cause more serious
accidents.
WARNING
Do NOT touch or open the shell after the inverter is powered off within
ten minutes.
The IPT series, a high-frequency sine wave inverter, adopts a fully digital intelli-
gent 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, emergen-
cy 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
① For inverters with 12V/24V input voltage, the RS485/RJ11 port has NO commu-
nication isolation design. This function (communication isolation design) is just for
inverters with 48V input voltage.

① Cooling Fan
• Conditions to start the cooling fan:
The heat sink temperature is higher than 45℃or The internal inverter temperature
is higher than 45℃or The output power is higher than 50% of the rated power
• Conditions to stop the cooling fan:
The heat sink temperature is lower than 40℃and The internal inverter tempera-
ture is lower than 40℃and The output power is lower than 40% of the rated power
②The AC output port varies with different products. Please refer to chapter
3 Naming Rule for the Specific Supported Types.

GFCI Socket Needs to be Tested After Power-on to Ensure Proper Operation.
A.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 socket. Turn on the inverter after
confirming the wiring.
B.Testing
1) If the red LED is ON solid, it indicates that the GFCI socket 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:
①The "TEST" button always pops up, and the night light keeps ON solid. It indicates that the GFCI
wiring is an error; please correct it.
②The "TEST" button goes down, while the "RESET" button pops up. The LED and the night light are
turned off, indicating the GFCI socket is normal (Note: Press the "RESET" button again to recover the
load output).
