SUSTAINABLE, INDEPENDENT POWER

The NTN-5K Series inverter is tailored for remote use with a built-in 4520W AC-DC charger, allowing for a rapid battery charging capability that integrates seamlessly with external energy sources, including solar panels. By supporting maximum power point tracking (MPPT) charger input, the NTN-5K can operate efficiently with renewable energy, enabling the possibility of a sustainable, independent power system even in the most challenging environments.

With modular scalability up to 30kW, the NTN-5K ensures that operations are not only uninterrupted but also adaptable as energy demands grow, giving users the versatility required for different operational needs. Its AC bypass function provides additional reliability by enabling the inverter to seamlessly switch to an alternative power source if needed, ensuring continuous power availability across various operational requirements.

The urgency of resilient, sustainable power solutions has intensified, especially as global reliance on renewable energy sources expands. Green energy is not only preferred in these remote applications but is often essential, as fossil fuel options are both costly and logistically challenging to maintain in such environments

SUPPORTING RENEWABLE

The NTN-5K Series is engineered to meet these needs, supporting renewable energy use while providing a robust and reliable power infrastructure. This inverter is also designed to protect sensitive equipment, featuring true sine wave output with less than three per cent total harmonic distortion (THD), minimising power quality issues. This feature is crucial in remote applications, where delicate electronics and equipment may otherwise be at risk.

Compared to other remote power solutions, the NTN-5K stands out with several advanced features that enhance reliability and adaptability. The inverter’s high surge capacity—peaking at 10kW—enables it to handle the significant power demands of equipment startup without interruptions. The system also incorporates robust protection measures, including safeguards against reverse polarity, over-voltage, short circuits, overload and overheating, providing peace of mind for engineers designing critical infrastructure.

Additionally, its communication capabilities allow integration with Modbus and CAN bus protocols, making remote monitoring and control easier and more efficient. Engineers can set the inverter to match specific load requirements by adjusting AC output voltage and frequency, offering optimal flexibility in design applications.

POWERING INDUSTRIAL SITES

The NTN-5K Series functionality is expected to be useful across a wide variety of sectors. Its robust design and versatile capabilities make it ideal for powering industrial sites where equipment, security and emergency devices are essential, particularly in locations without access to the grid, such as construction sites.

For mobile and outdoor applications, the inverter offers a reliable power source for vehicles, boats and remote stations, ensuring that essential operations remain online regardless of location. The system also serves as a dependable backup for residential and commercial properties, powering crucial devices like lighting, air conditioning and refrigeration during outages. For those adopting sustainable energy solutions, the NTN-5K pairs effectively with solar power setups, facilitating a continuous AC power supply in off-grid installations, particularly those aligned with renewable energy initiatives.

In terms of integration, the NTN-5K is designed to streamline setup and operation. Its compact 2U high chassis is compatible with a standard 19-inch rack, enabling straightforward incorporation into existing systems. Engineers looking to expand to three-phase configurations can easily connect three NTN-5K units, yielding a 3Ø4W AC output suitable for more complex setups. With options for remote ON/OFF control and digital monitoring via MEAN WELL’s CMU2E/CMU2E-R platforms, users can manage diagnostics and operational settings remotely, maximising uptime and energy efficiency.

SUSTAINABLE ENERGY PROJECTS

With the NTN-5K Series, MEAN WELL delivers a powerful, modular and highly adaptable solution for managing power in remote locations. This inverter serves as a dependable and flexible power source that design engineers can leverage to overcome the challenges of off-grid power needs or critical mains power backup, whether for industrial applications, mobile setups or sustainable energy projects. As a versatile and resilient tool, the NTN-5K is a crucial addition to the design engineer’s toolkit in the pursuit of reliable, continuous and independent power solutions.
