Frequently Asked Questions

We recommend MG, Victron and Valence Lithium-ion batteries with Oceanvolt electric motor systems. AGM batteries and other Lithium batteries can also be used, but not recommended.

Batteries can be charged using hydrogeneration while under sail, a DC generator, solar panels, wind generator or by plugging the boat to shore power.

Lithium-ion batteries will last 10 or more years if they are handled properly.

The Oceanvolt display continuously shows the charge level in real time. Should you run low on battery power, you can use the hydrogeneration function while sailing. Some customers have chosen to have a small portable generator (these can run on LPG or gasoline) on board to recharge the battery bank or to use as a temporary range extender. For larger boats Oceanvolt recommends a hybrid system which includes a permanent DC generator – this allows full enjoyment of all the benefits of the electric motor system without compromising range.

Managed properly, Lithium-ion batteries are perfectly safe and failures are rare. High quality manufacturers use multiple protection mechanisms to avoid problems. Be sure to understand proper battery care procedures in order to maintain the safety and lifespan of your batteries and the effectiveness of your Oceanvolt system.

Normally the weight of the battery bank is somewhere between 100kg and 300kg in a 35 – 55ft sailboat.

Charging your 12V DC or 24v DC house battery from the 48V DC propulsion battery bank can be easily facilitated via an inverter.

The battery banks are generally configured for 4-10 hours of motoring at the speed of 4-6 knots (about 30 – 40 nautical miles) but it also depends entirely on the customers preference and different use cases.

Oceanvolt electric motors deliver significantly more torque than any comparable diesel engine.  A 15kW Oceanvolt electric motor easily outperforms and is more powerful than a 30hp diesel engine.

Yes! Refitting an old diesel system will revitalize your boat, clean up the greasy engine compartment, reduce overall weight and free up space below deck.

We recommend MG, Victron and Valence Lithium-ion batteries with Oceanvolt electric motor systems. AGM batteries and other Lithium batteries can also be used, but not recommended.

Oceanvolt specializes in inboard electric motor systems and we do not offer outboard motors at this time.

First, check the battery charge and connections to ensure they are secure. Verify if the system's main switch is turned on and check for any error messages on the display. If the issue persists, consult the troubleshooting guide in our manuals or contact Oceanvolt support for further assistance.

Both systems include the complete propulsion system together with the throttle lever, display, batteries and chargers. A hybrid system also includes a DC generator.

No.  Electric motors deliver a higher level of performance, more efficiency (93%), less noise, minimal maintenance requirements and the ability to regenerate energy while under sail.  A DC hybrid has all of these benefits and even better range than with a comparable diesel engine due to higher efficiency.  A hybrid system delivers the best of both technologies.

Batteries can be charged using hydrogeneration while under sail, a DC generator, solar panels, wind generator or by plugging the boat to shore power.

Using shore power, it can take between 5 and 10 hours to charge the battery bank up to 100% – depending on the shore power source and the size of the charger.

Mauris sed libero. Suspendisse facilisis nulla in lacinia laoreet, lorem velit accumsan velit vel mattis libero nisl et sem. Proin interdum maecenas massa turpis sagittis in, interdum non lobortis vitae massa. Quisque purus lectus, posuere eget imperdiet nec sodales id arcu. Vestibulum elit pede dictum eu, viverra non tincidunt eu ligula.

Key factors include your boat type, weight, power requirements, battery capacity, and system integration with solar, wind, or shore power sources. Oceanvolt's experts will provide customized guidance for optimal performance.

Before we get our new Webshop up and running you can purchase spareparts (such as anodes and maintenance kits) by contacting support@oceanvolt.com

On the SD saildrives the propeller must be taken off before removing the anode.  This is to make sure that the contact between the anode and the sail drive is the best possible. On the ServoProp saildrives however it is possible to remove the anodes without removing the entire propeller.

Yes! Refitting an old diesel system will revitalize your boat, clean up the greasy engine compartment, reduce overall weight and free up space below deck.

Oceanvolt electric motor systems typically cost about 20-25% more than comparable diesel systems.  However, lower maintenance and fuel consumption (in a hybrid system) costs are considerably lower, so the difference in system cost can be recovered in about 2-3 years.

Hydrogeneration creates only 0.3-0.5 of a knot of drag at boat speed of 6.0 knots – so barely noticeable

For propulsion, yes. But not for hydrogeneration because the hydrogeneration function cannot be stopped with a fixed blade propeller.
