1. ntroduction
Thanks for purchasing TNI-SHI series inverters. The pro uct is a
pure sine wave inverter which can convert 12/24/48V c to 220/230Vac
50/60Hz base on full igital an intelligent esign. It features high
reliability, high efficiency, concise outline, small volume, full protection
functions, easy installation an operation. The inverter can be applie in
many fiel s, such as househol appliances, electric tools an in ustrial
evices etc, especially for solar photovoltaic power system.
Features:
 Complete isolation-type inverter technology.
 A option of a vance SPWM technology, pure sine wave output.
 Dynamic current loop control technology to ensure inverter reliable
operation.
 Wi e DC input voltage range.
 Low output harmonic istortion (THD≤3%).
 LED in icators for input voltage range, loa power range, normal
output & failure state.
 Optional energy saving mo e.
 The output voltage an frequency can be switche .
 Extensive protections: short-circuit, overloa , un er/over input
voltage, over-temperature, an inverter’s inner fault i entification
protections.
 Wi e working temperature range (in ustrial level).
 Continuous operation at full power.

2. mportant Safety nstructions
As an AC power supply equipment, the inverter’s output voltage is
with the same level as that of househol power plug. Min the AC output
terminals, or you may get an electric shock an result in life anger!
Attentions:
 Connect the DC input accor ing to the requirement strictly. The
power inverter has a relatively wi e input range, but too high or too
low input may cause problems even estroy the inverter. The surge
input voltage can’t excee 20V for the 12V inverters, 40V for 24V
inverters, 80V for 48V inverters, or the inverters will be amage .
 A reverse polarity connection will blow the fuses in the inverter an
may amage the unit.
 Do not expose the inverter to humi , flammable, explosive or ust
environment.
 Keep the inverter out of chil ren touch.
 Inverter input is recommen e to connect to battery, the min.
capacity of battery(expresse in AH) shoul be calculate in the
following way: 5times of the rate power of the inverter/battery
voltage. If for testing purpose, user shoul select DC power supply
current at least twice greater than that of the inverter rate input to
keep inverter normal operation. Use DC power supply for testing
may cause the amage of the inverter.
 When the inverter works continuously, its surface may became very
hot, please make sure the air ventilation clearance aroun the inverter
is more than 10cm. Keep away from the material or evice which
may suffer from high temperature when the inverter is working. Do
not install the inverter in airproof location an keep enough space
aroun the inverter.

 The protective groun ing must be connecte to the groun . The cross
section of wire shoul not be less than 4mm
2
.
 A fuse or breaker shoul be use between battery an inverter, the
value of fuse or switch shoul be twice of the inverter rate input
current.
 The wire connects between battery an inverter shoul be shorter
than 3m, the current ensity shoul be less than 3.5A/mm
2
while the
output of inverter is fully loa e . If the wire longer than 3m, the
current ensity shoul be re uce .
 Do not connect the battery charger or similar evices to the input
terminal of the inverter.
 Do not put the inverter close to the floo e lea -aci battery because
the sparkle in the terminals may ignite the hy rogen release by the
battery.
 It’s an off-gri inverter, if connect to the gri , the inverter may be
amage .
 This inverter can only be use singly, parallel connection or in series
will amage the inverters.
 Do not attempt to repair the fault inverter yourself, otherwise it may
lea to a serious acci ent. Please contact the manufacture’s engineer.

3. nverter Operation
Connect the input an output terminals accurately. Turn on the
power using the ON / OFF switch on the front panel. In or er to avoi the
protections resulte from the surge power, please turn on AC loa s 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 loa ’s plug into
the inverter’s output outlet.
 Connect the protective groun ing to the groun .
 Make sure the fuse or breaker use between battery an inverter is off.
 Connect the battery (‘+’ terminal with re line, ‘-’with black line). Do
not connect them by contraries, or the power inverter will be
amage .
 Switch on the fuse or breaker. Switch the inverter to ON an then
turn on the loa s one by one. Check the operation state of both power
inverter an loa s. ‘Green’ of the failure LED in icator means the
state is normal.
 If there are ifferent loa s, it is suggeste that turn on the loa with
large startup current first, such as television, then turn on the loa
such as lamp when the inverter works stable.
 If the failure LED in icator is ‘Re ’ an the buzzer alarms or no
output when you turn on evices, switch off the loa s an power
inverter imme iately. Check the system by referring to the
troubleshooting gui e. Turn on the evices again accor ing to the
operation metho s after the failure is remove .

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

Over Temperature Protection
The inverter will shut off when the internal temperature is
overheating. An it automatic restarts when the temperature recovers to
the normal level.
 Others
Saving Mode
When the switch is on “Saving” si e, the inverter will enter into the
Saving Mo e. It will shut off the output if the loa s value is less than
20VA. Then restart an etect the power of the loa again after 10s. If the
loa is more than 20VA, the inverter will turn on the output .Otherwise it
will shut off output again. It cycles like this. So please on’t use the
saving mo e if the loa is smaller than 20VA.

Mode Switch
The output mo e can be change by the mo e switch. When the
switch No.1 is on the ON si e, the inverter will enter into the saving
Mo e. This mo e can be switche online.
When the switch No.2 is on the ON si e, the output frequency is
60Hz，otherwise is 50Hz. When the switch No.3 is on the ON si e, the
output voltage is 230Vac, otherwise is 220Vac. Both the output frequency
an the output voltage change availability after restart the inverter.
Switch Node
The inverter can be control by the other equipment through the
switch no e. When the switch no e is link, it equal to ON/OFF switch is
on. The connection between the switch no e an the ON/OFF switch as
follow iagram:
If nee to use the switch no e, a relay shoul be use . The rating
current of the relay shoul not be less than 5A. The cross section of wire
nee s 1mm
