5kW UPS DC/AC Inverter with Charger 20…33Vdc/230Vac

NTN-5K is an all-in-one unit that integrates AC-DC charging, DC-AC inversion, and AC bypass. It also supports external solar panels and MPPT chargers. The main features include five key highlights:

1. Built-in high-power 4520W AC-DC charger with fast charging capability
2. Adopts a modular design with 5KW single machine module, allowing flexible parallel connection of AC outputs up to 30KW (1+5 units), with highly flexible wattage expansion
3. The chassis is designed in a 2U high cabinet style for easy installation and quick assembly when mounted in a standard 19 rack
4. Uses 3 NTN-5K single-phase AC outputs, which can be combined for 3Ø4W AC output use
5. Provides a comprehensive monitoring platform CMU2E, CM2E-R
