51′ NEEL Trimaran Victron Energy Installation Upgrade
Marine Battery & Power Generation System Upgrade Project
Are you considering upgrading or installing a new marine electrical system?
With the right system, you can increase your vessel’s power capacity, reliability, and reap the benefits of improved efficiency. Let’s explore the key benefits of a recent installation for a client that does just that. We will also explain how the new system is making a difference for not only the client and their guests, but also those on anchor around them.
The owners of Thri Day, a Neel 51 trimaran were seeking to upgrade the current lithium battery system to something a bit more capable. They contacted us at Maz Ocean to discuss the possibilities. The existing ship’s systems and A/C inversion were all powered by a 24V lithium battery bank. After discussing the clients’ requirements, we explained how a higher voltage system would benefit them given the power capacity desires and system recharge requirements.
A 48V solution with Victron equipment really made sense on Thri Day given the demands for power and extended run-time requests when away from the dock.
This new marine electrical system installation is centered around (10) 24V 200Ah Smart Lithium batteries in series/parallel.
This setup provides a whopping 1,000Ah at 48V. This battery bank powers (2) 48V Quattro inverter chargers:
One unit provides 10,000 watts of inversion to the 230V loads onboard
The other, strictly in inverter mode, offers 5,000 watts of inversion to the vessel’s 120V outlet circuits, which were originally 230V but, the owners needs were best served by converting for use in the US.
This battery bank, associated chargers, and inverters serve to supply the vessel with its comfort needs of AC power regardless of location through its rather impressive battery bank capacity and inverter capabilities.
The ship’s critical systems are powered by a separate Victron Lithium system composed of (2) Victron smart Lithium 330Ah units with redundant charging from the 48V battery bank, engine alternator, and solar.
Off-Grid Living with Integrel
So, our discussions turned to generator alternatives including DC generators, high output alternators, a solar-integrated bimini hard top. In the end, the much acclaimed Integrel system was chosen to provide the balance of the vessel’s energy needs.
With up to 9kw of power production pouring into the 48V battery bank when the vessel’s single Volvo engine is in operation, it is both a good return on investment to utilize the existing infrastructure as well as quite beneficial from the impressive power production capabilities of the Integrel system. This addition to the boat’s power plant offers a true off-grid solution for this client’s needs, while also helping the owners to make friends in every anchorage visited. No one likes a noisy neighbor. Thri Day will certainly impress on many levels.
