First hybrid yacht to cross the ocean / relies on by MG’s batteries

There are various types of lithium-batteries on the market. The brand we are using is they are best regarding liability, safety, performance, weight and life-span.

Their challenge

Solarwave 62 is the first hybrid yacht with electric propulsion to cross the Atlantic Ocean. The mighty cruiser built by Silent Yachts drove all the way from Spain to Miami, mainly powered by the sun. When necessary a generator gave support. Due to MG’s energy system it’s nearly self-sufficient, silent and emission-free, offering a whole new scale in reliability and luxury.

The energy system provides a grand capacity of of 160 kWh and consists of 2 lithium-ion battery banks, weighing less than 1000 kg. With a system voltage of 48 V it powers four 22 kW electric motors used for propulsion, two 15 kW bow thrusters and 3 phase 230VAC hotel supply with three 10 kVA Quattro’s. It’s charged by solar panels and a 20 kW DC generator.

Because it’s paramount the system needs to be redundant, the battery banks are set up in parallel. Even if one battery bank should fail, it still provides energy to the complete propulsion system, although in this situation the power will be limited. This redundancy is realized by using only the functions of the Master LV’s and some additional I/O’s and programmable relays.

Clever configuration enables autonomous running of charging/discharging and controls processes. Limits are set in case one battery bank should fail and/or is overloaded by discharge. The generator will automatically start when the battery bank is below 30% State-Of- Charge or when the current drawn from the battery is too high for a certain amount of time.

All status information from the battery banks is visible on Victron’s Color Control GX.
