What this video covers

A side-by-side performance test on a Leopard 50 compares the new Arco Zeus 48-volt high-output alternator against the established American Power Systems HBI 130. Under hot, steady-state operating conditions, the Arco unit produces approximately 6,000 watts, while the American Power Systems unit outputs 5,140 watts at the same RPM. The Arco system retails for $1,796, offering a $600 price advantage over the $2,396 American Power Systems model. High-voltage systems, such as 24-volt or 48-volt configurations, allow for significantly higher energy delivery compared to 12-volt setups, which typically peak in the 2,000-watt range. The Arco Zeus includes an external regulator with a wireless interface and a generator mode that allows users to adjust engine load protections for dedicated battery charging. This technology provides a viable alternative to installing a standalone diesel generator on smaller vessels where space is limited. High-output alternators effectively turn propulsion engines into high-capacity charging systems, enabling the operation of heavy loads like air conditioning and induction cooktops while underway.
