FAQ

What is the main purpose of the Mean Well NTS-1700-248AU inverter?

The NTS-1700-248AU is a 1700W true sine wave DC-AC inverter designed to convert 48V DC input power into 230V AC output. It is suited to professional and commercial applications that need clean AC power from a DC battery source.

Does this model provide true sine wave output?

Yes. The NTS-1700-248AU produces a true sine wave AC output with total harmonic distortion below 3%, which makes it suitable for equipment that requires stable, high-quality AC power. This is a key advantage over modified sine wave inverters for sensitive loads.

What input and output voltages does the NTS-1700-248AU use?

This model uses a 48V DC input (40-66VDC typical range) and is factory-set to 230V AC output. The AC output voltage is selectable by DIP switch between 200/220/230/240VAC, and the output frequency between 50Hz and 60Hz.

What is the surge capability of this inverter?

The NTS-1700-248AU is rated for 1700W continuous output and supports surge power up to 3400W. That extra surge capacity helps it handle loads with higher startup demand than their normal running power.

What battery types is the NTS-1700-248AU compatible with?

Mean Well specifies this inverter as suitable for both lead-acid and li-ion batteries. It also gives a low-voltage alarm at 44V and shuts down at 40V (restarting at 50V) to help protect the input battery system.

Can this inverter operate in demanding temperature conditions?

Yes. The NTS-1700-248AU has a wide operating temperature range from -25°C to +70°C, with output derating at higher temperatures according to Mean Well's derating curve. It is cooled by a built-in fan.

What protection features are included in this model?

This inverter includes protections for output short circuit, overload, over temperature and DC input high voltage, along with low-voltage shutdown to protect the battery from over-discharge. For overload conditions, the unit shuts down output voltage and requires re-powering to recover.

Does the NTS-1700-248AU support remote monitoring or remote control?

Yes. It supports power ON-OFF remote control and can work with optional remote controllers IRC1, IRC2, and IRC3, which are sold separately. It also supports RS-232 communication using the separately ordered RJ11-RS232 cable.
