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 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 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

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/mm2while 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.

If the overload or short circuit status still remains when the inverter

tries to recover for 3 times, you should reduce or clear the loads

and then restart the inverter manually. Load over than 250% will be

treated as output short circuit.
