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.
