Marine & Narrowboat Power Systems and Upgrades
Reliable Off-Grid Power — For Life on Water.
Whether you live full-time aboard or escape on weekend cruises, your boat’s power system should enhance your freedom, not limit it. At Van Junkies, we design and install dependable, efficient power systems for a wide range of watercraft, including narrowboats, widebeam boats, Dutch barges, canal boats, cabin cruisers, houseboats, motor yachts, sailing yachts, coastal liveaboards, riverboats, and offshore cruisers. If it floats and has a cabin, we can power it.
Why Upgrade Your Boat’s Electrical System?
Modern boaters expect more: laptops, lighting, fridges, induction hobs, TVs, even espresso machines. Old-school boat electrics simply weren’t built for this kind of lifestyle. Frequent engine running, limited solar, and dodgy wiring are common — but avoidable — issues. Our marine power upgrades are designed to:
Maximise energy capture
from solar, alternators, and shore power
Support 12V, 24V and 230V loads
with clean, stable output
Futureproof your system
with lithium compatibility and app monitoring
Protect your investment
with correctly specced fuse boxes, breakers and isolation
Lithium Battery Upgrades
Lighter, smarter, faster-charging. Lithium iron phosphate (LiFePO₄) is ideal for high-use systems.

High-efficiency MPPT controllers, marine-ready panels, and weatherproof wiring.
