The flagship of the new series is the Zeus A8000-48V. It has undergone significant further development: A newly designed rotor ensures that the machine runs more efficiently, produces less heat and still delivers plenty of power - at all speeds. That means in figures: Over 55 amps at 2,500 rpm and almost 111 amps at 4,000 rpm. At the same time, the device remains nice and compact - so it doesn't take up any extra space.
"Our customers wanted a 48V version with the usual Arco reliability," says Chris Witzgall, Head of Sales at Arco. "What they got is a real powerhouse that easily outperforms the competition - and takes up the same space as our 12V and 24V models."
Two new 24V versions of the Zeus generators
Arco is also stepping up its game in the 24V range: With the Zeus 7 kW High Output and the Zeus 4 kW Low Turn-On (LTO), two alternatives are coming on board that are optimised for different driving profiles. The LTO was specially developed for boats with low-revving diesel engines - perfect for anyone who likes to "chug along comfortably" in the harbour or at anchor and still needs power.
On the other hand, the Zeus 7 kW generator is just right for those who like to travel a little faster and want to draw plenty of power. It delivers more than 5 kW of continuous power at operating temperature - and at a price that is really impressive.
Made in USA
The generators are manufactured in the USA, where Arco has been producing motor and electrical components for the marine industry for decades. The company launched the first models in the Zeus series - the A275L and A225S - back in July 2024. With the new series, Arco now wants to hit the ground running and establish innovative, high-performance products in the upper class.
