NTS & NTU Series
High Reliable Inverter
True Sine Wave Inverter
Installation manual

NTS/NTU series are MEAN WELL's new generation high-reliability off-
grid DC-AC pure sine wave inverters. The whole family has
NTS-250P/400P, NTS-300/450/750/1200/1700/2200/3200,
and NTU-1200/1700/2200/3200 series . The whole family of NTS/NTU are
fully digital designed, with three major characteristics of miniaturization,
high efficiency, and intelligence. The main features are, instantaneous
peak load capacity which can reach up to 2 times of output wattage, as
well as AC output voltage/frequency/power saving mode adjustment
capability through the DIP switch of front panel (the idle standby
consumption is 1.5W). It s efficiency reaches up to 93%, and it can be’
operated within temperature range from -25~+70 . Built-in remote℃
control, able to monitor the battery voltage and the load status of the
inverter through IRC1/2/3. Not only intergrated multiple intelligent
protections, but also passed safety regulations such as
CB/DEKRA/E13/EAC/UL/RCM/FCC/CE. Materials and components are
strictly selected and 3-year warranty is provided. It is suitable for
households, vehicles, yacht and remote areas without power grids.
Common application such as, lighting, air conditioning, refrigerators, hair
dryers, microwave ovens , computers, televisions, hand-held power tools,
motor equipment, mobile AC power... etc.

1 Safety Guidelines.
nRisk of electrical shock and energy hazard. All failures should be examined
by the qualified technician. Please do not remove the case of the inverter
by yourself.
nPlease do not install the inverter in places with high moisture or near
water.
nPlease do not install the inverter in places with high ambient temperature
or under direct sunlight.
nPlease only connect batteries with the same brand and model number in
one battery bank. Using batteries from different manufacturers or
different capacity is strictly prohibited!
nNever allow a spark or flame in the vicinity of the batteries because they
may ignite explosive gases during normal operation.
nMake sure the air flow from the fan is not obstructed at both sides (front
and back) of the inverter. (Please allow at least 15cm of space)
nPlease do not stack any object on the inverter.
nPlease do not turn on the inverter before start the engine if inverter
connected to vehicle's battery directly.

Please turn off the inverter first.
Select proper cable for connection between battery and inverter by
referring to section 3.4
Connect the positive polarity of battery to the positive of inverter,
and connect the negative polarity of battery to the negative of
inverter.
Turn the power switch to ON position as soon as it shows green in"" ,
status s LED, then it s ready.’’
Wire connections should be as short as possible and less than 1.5
meter is highly recommended. Make sure that suitable wires are
chosen based on safety requirement and rating of current. Small
cross section will result in lower efficiency, less output power and
the wires may also become overheated and cause danger. Please
refer to table 3-1.

AC output socket : Please refer to Pg. 16 for varies socket for different

No fuse breaker with reset button (only for NTU-1200/1700/2200/
3200 GFCI series ; NTU 1200 1700 2200 3200 series) :-///
Under "bypass mode", when the AC output is shorted or the load
current exceeds the rated current of the No fuse breaker, the breaker
will trip and that stops bypassing energy for the utility thus prevent
possible danger. When the abnormal condition is cleared, the user
can press down on the reset button to resume operation.
Ventilation slits: The inverter requires good ventilation for proper
operation and prolonging its lifetime.
LED indicators : Indicate the status of inverter and the load condition.
Communication port: For remote monitoring purpose, the unit can
be connected to a PC through this communication port by using the
or a cable and monitoring software. Also for remote control purpose,
the unit can be connected to the IRC module through this port.
Power ON/OFF switch : The inverter will turn ON if the switch is in the
ON position, and vice versa.
FG connection
Remote ON/OFF : Inverter will turn on if the pins of RC connector is
open. And, inverter will turn off if the pins are shorted.
AC bypass socket : When AC mains is available, by connecting the AC
mains to the AC socket, it will enable AC bypass function, which the
energy will provide to load from AC mains directly.

When input voltage is greater than 12.5V(12V)/25V(24V) 50V(48V).
Orange light：
When input voltage is within 11V 12.5V(12V)/22V~25V(24V)/44V~50V(48V).~
Red light：
When input voltage is lower than 11V(12V)/22V(24V)/44V(48V) or over it's
specification. It flashes and warning sound will be activated.

5.1.1 Output Voltage and Frequency Setting
Factory settings are either 110Vac/60Hz or 230Vac/50Hz, users are able to
adjust the voltage and frequency, through the DIP switch of position 1,2,3
on the AC panel.
Power Saving Mode setting
When the inverter is in no load status, in order to reduce battery
energy consumption by inveter accidentally, Position 4 of DIP S.W.
on the panel of inverter, can be adjusted to the "ON" position.
When this mode is activated, if the load is less than 10W, the
inverter will turn off the output and enter the power saving mode
after 3 second. In the power saving mode, the inverter MCU will
periodically detect the output load status. When a load greater
than 25W is connected, the inverter will switch back to normal
mode and start output again. (Non-power saving mode is used as
factory setting)

5.4 RS-232 Protocol
RS-232 communication can be used between NTS/NTU series products
and external controller (Controller) or PC software. The internal data of
single NTS/NTU can be set or read through RS-232, but Multiple units
in a bus is not allowed.The RS-232 of NTS/NTU series are defined as
follows.
