Modified and pure sine wave inverters

SMARTIN is the new line of inverters designed and developed by NDS, which has managed to create a series of professional products that is up to their customers’ expectations.
These Inverters have been designed to guarantee the best performance in terms of safety, efficiency and reliability. Thanks to some special technical and innovative solutions, SMARTIN inverters are also suitable for professional use.

There are two series of SMARTIN, Modified and Pure based on the type of output wave-form.
For both models, there are 400W, 600W, 1000W and 1500W versions.
Besides the cables included, to complete the o er of the SMARTIN, a series of a practical accessories are available.

Main features

High efficiency up to 93%
Low self-consumption
Input with professional connectors
Predisposition for remote control ON/OFF
Input and output completely isolated


Soft Start
Protection against overload and shortcircuit
Low battery alarm
Protection against polarity inversion
Over-temperature protection

Distinctive features:

  • The input and output are completely isolated, to avoid that any anomalies from the equipment connected to the output may damage that connected to the input and vice-versa, thus ensuring a high degree of safety.
  • Professional connectors which, as opposed to the standard cheaper inverters on the market inverters normally sold, are directly integrated into the board, thus allowing substantial reduction of voltage drop on the connection between the device and the battery. This improves its performance and, at the same power absorbed by 230V equipment (e.g. TVs), the battery consumption is lower than with the traditional inverters.

Thanks to the innovative technical solutions adopted, the efficiency can get to very high levels:

  • 93% for the modi ed wave SMART-IN SM series, suitable for TVs, computers, battery chargers and so on.
  • 91% for the pure wave SMART-IN SP series, recommended for all uses as all the devices are designed and tested to work with pure sine wave voltage.

For some equipment, such as engines, refrigerators, Hi-Fis, “dimmer” lamps and air conditioning systems, using a pure sine wave inverter is compulsory in order to avoid any damage. SMART-IN inverters can boast the lowest self-consumption on the market and considering that very often an inverter remains in stand-by mode, thus keeping consuming current, to mimimize the absorption is essential and of great bene t to the user that does not discharge the battery unnecessarily.



SMART-INPURE with IVT function is a line of inverters with an integrated system of priority (Priority Switch type). This special IVT function, through the two input and output 230V sockets, allows the management of the voltage that comes out from the inverter connected to the battery and to the external grid.

When the main is connected to the external grid, it will have the priority in order to preserve the battery; when the grid is disconnected, the inverter will supply the 230V output socket and the entire system.
