1. Important Safety Instructions
As an AC power supply equipment, the inverter's output voltage is at the same level as that
of the household power plug. Mind the AC output terminals, or you may get an electric
shock and result in life danger!
Attentions:
Connect the DC input according to the requirement strictly. The IPower inverter has a
relatively wide input range. Still, too high or too low input may cause problems even
destroy the inverter.
A reverse polarity connection will blow the fuses in the inverter and may damage the
unit.
Do not expose the inverter to a humid, flammable, explosive, or dust environment.
Keep the inverter out of children's touch.
Inverter input is recommended to connect to the battery. The minimum capacity of the
battery(expressed inAH) should be calculated in the following way: 5times of the rated
power of the inverter/battery voltage. If for testing purpose, the user should select DC
power supply current at least twice greater than that of the inverter rated input to keep
normal inverter operation. Use a DC power supply for testing may cause damage to
the inverter.
When the inverter works continuously, its surface may become very hot; please ensure
the air ventilation clearance around the inverter is more than 10cm. Keep away from
the material or device which may suffer from high temperature when the inverter is
working. Do not install the inverter in an airproof location and keep enough space
around the inverter.
The protective grounding must be connected to the ground. The cross-section of the
wire should not be less than 4mm2.
The wire connection between the battery and inverter should be less than 3m, and the
current density should be less than 3.5A/mm2. At this time, the inverter is running at full
load. If the wire length is greater than 3m, the current density should be reduced.
A fuse or breaker should be used between the battery and inverter. The value of the
fuse or breaker should be twice the inverter's rated input current.
Do not connect the battery charger or similar devices to the inverter's input terminal.
Do not put the inverter close to the flooded lead-acid battery because the terminals'
sparkle may ignite the hydrogen released by the battery.

2
It's an off-grid inverter. Do not connect the AC output terminals to the grid or electrical
source; otherwise, the inverter may be damaged.
This inverter can only be used singly in parallel connections. The series connection will
damage the inverters.
Risk of electric shock, don't touch the output port when the inverter is working. The
output is forbidden to connect to other power sources or grid; otherwise, the inverter
will be damaged. The inverter must be turned off when connecting the load.
Do not attempt to repair the fault inverter by yourself; otherwise, it may lead to a
serious accident. Please contact the manufacture's engineer.
IPower series is only suitable for civil applications, not for industrial applications.

2. Introduction
IPower series is a kind of pure sine wave inverter that can convert 12/24/48VDC to
220/230VAC(or 110/120VAC). Compared with civil design, industrial design has a wide
operating temperature, high reliability, and high efficiency. Simple appearance and
lightweight make it easy to install and operate. The wide input voltage range is ideal for
solar system applications. This inverter is especially suitable for civil applications, such as
household emergency lighting systems, vehicle-mounted systems, small field power supply,
etc.
Features:
Safe design with input and output electrical isolation
Adoption of advanced SPWM technology, pure sine wave output
Optional output voltage 220/230VAC(or 110/120VAC), choosing by DIP switch
LED indicators for fault status and working status
Lower No-load consumption
Max. efficiency up to 95%(IP2000-22, IP2000-42)①
Input protection: Over voltage protection, low voltage protection
Output protection: Overload protection, short circuit protection
Over-temperature protection: Temperature-controlled Fan Ventilation; Inverter turns off
automatically when overheating
Operational USB output 5VDC/1A
Operational RS485 communication port②
①The efficiency is tested at rated input voltage,220V output with resistive load, 25℃
Ambient temperature,1500W and higher version
②1000W and higher version support RS485 communication port optional.

(2) 220/230V AC(or 110/120V) output
Operation Steps:
Step 1: Turn the power switch of the inverter to OFF
Step 2: Disconnect the input breaker or the fuse between the inverter and battery, connect
the battery terminals ('+' with the red line and '-' with the black line). Do not connect
the poles by contraries.

6
Step 3: Use the cable no less than 4mm2to connect the inverter's grounding terminal to the
ground.
Step 4: Connect the plug of AC load to the inverterAC outlet
Step 5: Switch on the input breaker or the fuse between the inverter and battery; turn on
the power switch to start the inverter. If the green indicator is on solid, turn on the
loads one by one. Check the operation state of the inverter and loads.
Step 6: If there are different types of loads, the loads with higher startup current should be
turned on firstly, such as television. After the loads work stably, turn on the loads
with a lower startup current, such as an incandescent lamp.
Step 7: If the Fault indicator is red and the buzzer alarms when turning on the devices,
please switch off the loads and inverter immediately.
Note: When using a USB port for charging, it is suggested to charge the
power bank first and then use the power bank to charge mobile phones.

①When output overload protection or load short circuit protection is activated, the
AC output would auto-recovery three times (the first time delays for 5s, the
second time delays for 10s, and the third time delays for 15s). After then the AC
output would not auto-recover, and it can only be recovered after restarting the
inverter. (When S=1.2Pe, the models don't have the auto-recovery function,
except IP350 and IP500.)
②IP350 and IP500 stop output after 1minute.

When the heat sink temperature
exceeds 80℃, or the internal

automatically turns off the output. When
the heat sink temperature goes below
70℃, or the internal temperature goes
below 50℃, the inverter resumes work.

8. Maintenance
The following inspections and maintenance tasks are recommended at least two
times per year for best performance.
Make sure no block on air-flow around the inverter. Clear up any dirt and fragments on
the radiator.
Check all the naked wires to make sure insulation is not damaged for serious
solarization. Frictional wear, dryness, insects or rats, etc. Repair or replace some wires
if necessary.
Check and confirm that indicator and display are consistent with required. Pay
attention to any troubleshooting or error indication. Take corrective action if necessary.
Confirm that all the terminals have no corrosion, insulation damaged, high temperature,
or burnt/discolored sign, tighten terminal screws to the suggested torque.
Check for dirt, nesting insects, and corrosion. If so, clear up in time.
Check and confirm that the lightning arrester is in good condition. Replace a new one
in time to avoid damaging the inverter/charger and even other equipment.
WARNING：Risk of electric shock!
Risk of electric shock! Before the above operations, ensure that all the power is turned off.
The electricity in the capacitances is completely discharged, then follows the corresponding
inspections and operations.

Damage caused by improper use or use in an inappropriate environment
Battery voltage exceeds the input voltage limit of the inverter
Damage caused by working environment temperature exceeds the rated range
