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.

2
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.
It is recommended that the connection length between the battery and the

3
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 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 modules of the inverter 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
After the inverter stop running for five minutes, the internal conductive modules could be touched.
The inverter is allowed to restart after removing the faults, which affects 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 there is no voltage and
current.
When conducting electrical connection and maintenance, post a temporary warning sign or put up
barriers to prevent unrelated personnel from entering the electrical connection or maintenance area.
An improper operation of the inverter may cause personal injury or equipment damage.
Please wear an anti-static wrist strap to prevent static damage or avoid unnecessary contact with
the circuit board.

1 Overview
IPower-Plus is a new generation of pure sine wave inverter compatible with the lithium battery system.
This new inverter adopts surge current suppression technology to effectively prevent the surge current
from damaging the lithium battery cells and BMS (Battery Management System). Also, adopting the
voltage and current double closed-loop control algorithm brings the inverter a faster response and better
resistance to the load impact. The inverter selects key components with a high power density and long
lifespan to provide a stable and reliable power guarantee. The optional communication solutions allow
users to monitor the real-time status or change the parameters wherever.
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 an excellent EMC (Electro Magnetic Compatibility) characteristic, the inverter is
also suitable for occasions with high power quality requirements.
Features:
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.
Input surge current suppression technology, applying to the lithium battery system
Outstanding load resistance to impact, applying to the air conditioners, washing machines,
refrigerators, etc.
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 protections: input reverse polarity/under voltage/over voltage, output overload/short
circuit/overheating
Air cooling is controlled by temperature and load
Rotatable LCD meter to simplify the system wiring①
Friendly LCD meter to simply monitor and parameter configure①
Remote control by the phone Apps and PC software
Configurable output voltage, output frequency and baud rate②
Enable power saving mode(PSE) conveniently②
Charging mobile phones, DC fans, and other electrical equipment by the USB port③

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).
CAUTION
For detailed product model Vs. AC output port; please refer to the “IPower-Plus
