Lithium house banks
Replace tired lead-acid with safe LiFePO4 — more usable power, far less weight, longer life. Independent BMS, marine-grade install.
Solar & charging
Deck and bimini solar, DC-DC and shore-power charging tuned to your battery, with smart monitoring you can check from your phone.
Inverters & 240V
Victron inverter/chargers for clean 240V onboard, switchboards and galvanic isolation done properly to standard.
Certified Victron Energy distributor. We design for the marine environment — vibration, salt and damp — and back it locally.
