LiFePO4 Batteries & Alternative Energy

Harbor Marine is bringing the power of LiFePO4 to the Key West yachting community.  Cruise off-grid without compromising comfort.  We can design and install a system that will allow you to sail with air conditioning, cook with electric, and even take a hot shower without ever firing up the generator!

​

Lithium energy storage is becoming increasingly popular for our cruising clients as the long term price point has become competitive with traditional lead-acid batteries.  Higher capacity in less space, better performance with integrated cell balancing and remote Bluetooth monitoring; LiFePO4 is the modern solution to off-grid energy storage.

​

We offer complete system design to meet your individual needs.  You will not regret choosing Harbor Marine to build your new system.

​

​

Harbor Marine is proud to partner with Victron Energy to deliver the highest standards in the marine industry.
