Oceanvolt systems are scaled and configured to achieve maximum efficiency – taking into consideration boat length, beam and displacement as well as system weight and placement within the boat.  Range, beyond battery capacity, is extended through hydro generation while sailing above 6kn.  This can be complemented with either a portable AC generator or a DC generator (in larger boats or for long distance cruising).

All Oceanvolt systems are engineered to operate at 48 volts for passenger safety and ease of repair. Oceanvolt systems are extremely low maintenance and do not require winterizing (no annual engine maintenance/storage costs).
