Key Advantages:
Zero noise, zero vibration – Unparalleled comfort while cruising or at anchorEnergy independence – Maximized solar power utilizationLower carbon footprint – 40% fewer emissions compared to conventional yachts
Fast, Efficient, Reliable: Generator-Fast-Charge Mode
With the Generator-Fast-Charge Mode, GX Superyachts take energy efficiency to the next level:

80% charge in less than 3 hours using onboard generators, enable you for another 48h on anchor only of the battery.
Variable speed generators seamlessly integrated into the system for optimal performance.
By running the fast charge generators for only 3h vs 24h running conventional hotel load generator we save up to 66% on consumption and emission impact
