Trimaran Actual Leader sails with MG’s high energy system / in redundant setup

Project / story

Their challenge

When racing a highly-advanced trimaran with sails the size of a basketball court on transatlantic routes, performance is everything.

All systems on board the high-speed sailing yacht Actual Leader run on 24VDC. Not a single 230V application is installed, in order to save weight of convertors or adapters, avoid risk of damage to ‘unnecessary’ parts, minimize energy loss and increase safety on board.

To stay ahead of competition every kilo counts, so the multihull’s energy system is required to be powerful and lightweight. In search of batteries with they highest energy density the team selected MG’s HE Series, based on state-of-the-art NMC technology with the highest kWh/kg-ratio. These modules deliver maximum performance from minimal mass.

Especially on big seas in strong wind, it’s critical to have an energy system that’s robust and reliable. MG’s batteries surpass the highest standards when it comes to safety. In addition they offer a key feature, unique in this industry: to set up the system in redundant mode.

In this case the installation consists of 2 MG Master LV‘s (400A) and 3 MG HE Series batteries (24 V / 100 Ah). The first master controls two batteries connected in parallel and the second master manages the third battery. Both groups communicate but operate independently, so even when one fails, the systems will continue running on the other one.

This way the entire energy yields 5 kWh and 2.5 kWh, while only weighing 56,3 kg.

Both groups are monitored in the pilot cabin by the new touch-screen MG Energy Monitor. Once connected to a hotspot these panels give direct access to the online MG Energy Portal. Everything is optimized, so the Actual Leader can live up to its name.
