5kW 6kW 7kW NK-G2 Single-phase Hybrid Inverter for Home Use
The G2 hybrid inverter has been cleverly adapted to achieve an optimal product size and weight, resulting in a leaner, lighter unit. At the same time, it is equipped with a touch screen display for a more intuitive view of the inverter's parameters, making it easier to adjust and monitor. This adjustment reduces labor installation costs by 50% and increases full load efficiency by 0.5%. It seamlessly installs 18.5A solar panels with a maximum output of 12 kW. This adaptability provides greater freedom in system design and integration, allowing users to expand capacity based on their energy storage needs. Notably, it supports parallel connection of up to 6 units.
