Marine Power Inverters

Choosing a marine power inverter

A marine power inverter converts suitable battery power into AC power for selected onboard devices. The right inverter depends on the appliance load, startup demand, battery capacity, cable length and how often the equipment will be used away from shore power.

Before choosing an inverter, review the devices you want to run and compare their combined draw with the inverter rating. Battery capacity matters just as much as inverter size, so consider the wider electrical setup including marine batteries, marine electrical wire and circuit protection.

Inverter buying checks

• Confirm continuous and peak wattage requirements for the intended devices.
• Check battery capacity and charging arrangements before adding large loads.
• Plan cable length, ventilation space and access around the installation point.
• Follow the product manual and use a qualified installer where required.
