1. Introduction

Thanks for purchasing SHI series inverters. The product is a pure
sine wave inverter which can convert 24/48Vdc to 220/230Vac
50/60Hz based on full digital and intelligent design. It features high
reliability, high efficiency, concise outline, small volume, full
protection functions, easy installation and operation. The inverter
can be applied in many fields, such as household appliances,
electric tools and industrial devices etc, especially for solar
photovoltaic power system.

Features:

 Complete isolation-type inverter technology.
 Adoption of advanced SPWM technology, pure sine wave

output.

 Dynamic current loop control technology to ensure inverter

reliable operation.

 Wide DC input voltage range.
 Low output harmonic distortion (THD≤3%).

 LED indicators for input voltage range, load power range,

normal output & failure state.

 Optional energy saving mode.
 The output voltage and frequency can be switched.

 Extensive protections: short-circuit, overload, under/over input

voltage, over-temperature, and inverter‟s inner fault
identification protections.

 Wide working temperature range (industrial level).
 Continuous operation at full power.

2. 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.
The surge input voltage can‟t exceed 40V for 24V inverters,
80V for 48V inverters, or the inverters will be damaged.

 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 in AH) 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 became

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

3

and keep enough space around the inverter.

 The protective grounding must be connected to the ground. The

cross section of wire should not be less than 4mm2.

 A fuse or breaker should be used between battery and inverter,

the value of fuse or switch should be twice of the inverter rated
input current.

 The wire connects between battery and inverter should be

shorter than 3m, the current density should be less than

3.5A/mm2 while the output of inverter is fully loaded. If the wire
longer than 3m, the current density should be reduced.

 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 risk, don‟t touch output port when the inverter is

working. The output is forbidden to connect other power,
otherwise the inverter will be damaged. The inverter must be in
off, when connecting load.

 Do not attempt to repair the fault inverter yourself, otherwise it

may lead to a serious accident. Please contact the manufacture‟
s engineer.

3. Inverter Operation

Connect the input and output terminals accurately. Turn on the
power using the ON / OFF switch on the front panel. In order to
avoid the protections resulted from the surge power, please turn on
AC loads one by one after the output of the inverter is normal.
Please check it as below:

 Set the power switch to the „OFF‟ position. Insert the load‟s plug

into the inverter‟s output outlet.

 Connect the protective grounding to the ground.
 Make sure the fuse or breaker use between battery and inverter

is off.

 Connect the battery („+‟ terminal with red line, „-‟with black line).

Do not connect them by contraries, or the power inverter will be
damaged.

 Switch on the fuse or breaker. Switch the inverter to ON and then

turn on the loads one by one. Check the operation state of both
power inverter and loads. „Green‟ of the failure LED indicator
means the state is normal.

 If there are different loads, it is suggested that turn on the load

with large startup current first, such as television, then turn on the
load such as lamp when the inverter works stable.

 If the failure LED indicator is „Red‟ and the buzzer alarms or no

output when you turn on devices, switch off the loads and
power inverter immediately. Check the system by referring to the
troubleshooting guide. Turn on the devices again according to
the operation methods after the failure is removed.

Note：1.When the load current is less than 10A, use "AC outlet ①"
or “AC outlet ②"; If the load current is greater than 10A, must use
“AC outlet ②".

2.The cross section of wire should not be more than 4mm2 , and it
is recommended to use stranded wire, when using " AC outlet ②".

3.Stop inverter working firstly, insert a sharp tool to the " AC outlet
②" at the top of the holes and then remove the wire.

Input Low Voltage Protection

The output is switched off when the input voltage is lower than low
voltage protect value, and auto-switched on when the input voltage
reach low voltage recover value. User can also manually restart the
inverter to switch on output by the „ON/OFF switch‟, when the input
voltage is higher than low voltage protect value.

Fault Protection

The inverter will shut down when the output voltage is error or when
the inverter has inner fault.

Over Temperature Protection

The inverter will shut off when the internal temperature is over-

10

heating. And it automatic restarts when the temperature recovers to
the normal level.

 Others

Saving Mode

When the switch is on “Saving” side, the inverter will enter into the

Saving Mode. It will shut off the output if the loads value is less than
50VA. Then restart and detect the power of the load again after 10s.
If the load is more than 50VA, the inverter will turn on the output.
Otherwise it will shut off output again. It cycles like this. So please
don‟t use the saving mode if the load is smaller than 50VA.

Mode Switch

The output mode can be changed by the mode switch. When the
switch No.1 is on the ON side, the inverter will enter into the saving
Mode. This mode can be switched online.

When the switch No.2 is on the ON side, the output voltage is
230Vac, otherwise is 220Vac.When the switch No.3 is on the ON

side, the output frequency is 60Hz，otherwise is 50Hz. Both the
output frequency and the output voltage change availability after

restart the inverter.

11

Switch Node

The inverter can be control by the other equipment through the
switch node. When the switch node is link, it equal to ON/OFF
switch is on. The connection between the switch node and the
ON/OFF switch as follow diagram:

POS(+)

NEG(-)

ON/OFF

Switch

If need to use the switch node, a relay should be used. The rating
current of the relay should not be less than 5A. The cross section of
wire needs 1mm2.
