LiFePO4 Marine House Battery Kits for Boat Onboard Power

A marine house power kit is a ready-matched marine power system designed to support onboard essentials such as boat lights, pumps, refrigerators, electronics, and selected AC appliances. It is built for longer fishing trips, overnight stays, and off-grid boat use.

The 330Ah kit is designed for essential onboard loads and alternator charging support. The 400Ah kits provide more capacity for longer runtime, making them a better fit for boaters running refrigerators, electronics, pumps, and other house loads for extended use.

Choose the 330Ah kit for essential onboard loads and a simpler charging setup. Choose the 400Ah solar-ready kit if you need longer DC runtime with solar input, or choose the 400Ah off-grid kit if you also need AC appliance support through an inverter.

Yes, selected kits include a 12V 60A DC-DC charger to support alternator charging while your boat is underway. This gives boaters another way to recharge house batteries during travel.

Selected kits include a 60A MPPT solar charge controller for solar input. This helps extend your boat energy solution when dock power is unavailable or when spending more time away from shore.

The full off-grid kit includes a 3000W pure sine wave inverter to support selected AC appliances and tools. Actual performance depends on appliance wattage, battery capacity, usage time, and total onboard power demand.

LiTime Marine House Power Kits are supported by the applicable LiTime warranty, customer service, and after-sales support. If you need help choosing between 330Ah, 400Ah solar-ready, or 400Ah off-grid setups, LiTime support can help you review your onboard loads, charging method, inverter needs, and overall marine power system requirements.
