1. Important Safety Instructions
As an AC power supply equipment, the inverter’s output voltage is
with the same level as that of 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
power inverter has a relatively wide input range, but 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 humid, flammable, explosive or
dust environment.
Keep the inverter out of children touch.
Inverter input is recommended to connect to battery, the min.
capacity of battery(expressed inAH) should be calculated in the
following way: 5times of the rated power of the inverter/battery
voltage. If for testing purpose, user should select DC power
supply current at least twice greater than that of the inverter
rated input to keep inverter normal operation. Use DC power
supply for testing may cause the damage of the inverter.
When the inverter works continuously, its surface may become
very hot, please make sure 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 airproof location
and keep enough space around the inverter.
The protective grounding must be connected to the ground. The

2
cross section of wire should not be less than 4mm2.
The wire connects between battery and inverter should be
shorter than 3m, the current density should be less than
3.5A/mm2while the output of inverter is fully loaded. If the wire
longer than 3m, the current density should be reduced.
A fuse or breaker should be used between battery and inverter,
the value of fuse or breaker should be twice of the inverter rated
input current.
Do not connect the battery charger or similar devices to the
input terminal of the inverter.
Do not put the inverter close to the flooded lead-acid battery
because the sparkle in the terminals may ignite the hydrogen
released by the battery.
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, parallel connection or in
series will damage the inverters.
Risk of electric shock, don’t touch output port when the inverter
is working. The output is forbidden to connect other power
sources or grid, otherwise the inverter will be damaged. The
inverter must be in off, when connecting 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.

2. Introduction
IPower series is a kind of pure sine wave inverter which can convert.
12/24/48VDC to 220/230VAC(or 110/120VAC). Industrial design,
compared with the civil design, has a wider operating temperature,
easy installation and operation. The wide input voltage range is
ideal for solar system application. The inverter can be applied in
many fields, such as household emergency lighting system, vehicle
mounted system and 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: Over load 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.

Operation Steps:
Step 1: Turn the power switch of the inverter to OFF
Step 2: Disconnect the input breaker or the fuse between inverter
and battery, connect the battery terminals (‘+’ with red line and ‘-’
with black line). Do not connect the poles by contraries.
Step 3: Use the cable no less than 4mm2to connect the grounding
terminal of the inverter to the ground.
Step 4: Connect the plug of AC load to the inverter AC outlet
Step 5: Switch on the input breaker or the fuse between 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, it is suggested that turn
on the loads with higher startup current first, such as television,
then after the loads works stably, turn on the loads with lower
startup current, such as incandescent lamp.
Step 7: If the Fault indicator is red and the buzzer alarms when turn
on the devices, please switch off the loads and inverter
immediately.
Note: When use 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-recover for 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 auto-recover function, except IP350 and IP500)
②IP350 and IP500 stop output after 1minute.

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 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 is 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 lightning arrester is in good condition. Replace a
new one in time to avoid damaging of the inverter/charger and even
other equipments.
WARNING：Risk of electric shock!
Risk of electric shock! Before above operations, make sure that all the power is
turned off, and the electricity in the capacitances is completely discharged,
then follow the corresponding inspections and operations.
9. Disclaimer
The warranty does not apply under the following conditions:
Damage caused by improper use or use in inappropriate environment
Battery voltage exceeds the input voltage limit of inverter
Damage caused by working environment temperature exceeds the rated
range
Unauthorized dismantling or attempted repair
Damage occurred during transportation or handling
Damage caused by force majeure
