1. Introduction
Thanks for purchasing TNI-SHI series inverters. The product is a
pure sine wave inverter which can convert 12/24/48Vdc 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 20V for the 12V inverters, 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 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, if connect to the grid, the inverter may be
damaged.
This inverter can only be used singly, parallel connection or in series
will damage the inverters.
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.
