high-frequency pure sine wave inverter ("inverter" referred to in this manual).
1. Explanation of symbols
Please read related literature accompanying the following symbols to efficiently use the product and
ensure personal and property safety.
The entire system should be installed by professional and technical personnel.
Symbol
Definition
TIP
Indicate 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, may cause the device
damaged.
WARNING: Indicates the danger of electric shock, if not avoided, 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.
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
When you receive the inverter, check whether there is any damage that occurred in transportation.
Contact the transportation company or our company in time for any problem.
When place or move the inverter, must follow the instructions in the manual.

2
When installing the inverter, you must evaluate whether any arc danger exists in the operation area.
The inverter needs to be connected to a battery. The battery's minimum capacity (Ah) is
recommended to be five times the current equals the inverter's rated output power divided by the
battery voltage.
Keep the inverter out of reach of children.
This inverter is an off-grid type. It is strictly prohibited to connect the inverter to the grid; otherwise, it
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
Before installation, make sure the inverter has no electrical connection.
Ensure 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
Check whether all the wiring connections are tight to avoid the danger of heat accumulation due to
loose connections.
The protective grounding must be connected to the ground. The cross-section of the wire should not
be less than 4mm2
The DC input voltage must strictly be following 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 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 other power sources or
utilities; otherwise, the inverter will be damaged. Turn off the inverter when connecting loads.
Do not connect battery chargers or similar products to the inverter's input terminal; otherwise, the
inverter will be damaged.
7. Safety cautions for controller operation
When the inverter is working, the shell will generate a lot of heat. The temperature is very high;
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.

3
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.
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.

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

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
It is recommended to connect the inverter DC input terminal to the battery terminal
directly. 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.
