Collection: Inverters

Converting your boat's DC battery power into usable AC electricity is what this category is built around, and the two brands here, Samlex America and Xantrex, cover the full range of onboard needs. Samlex pure sine wave inverters run from 300W all the way to 3000W and are available in both 12V and 24V configurations, so the first thing to confirm before buying is your battery bank voltage. Pure sine wave output matters when you are running sensitive electronics, variable-speed motors, or medical devices, since it replicates the clean waveform of shore power rather than the stepped approximation a modified sine unit produces.

Xantrex rounds out the selection with hard-wired units like the PROsine 1800 and the Freedom SW series, which are designed for permanent installation and support optional accessories including a dedicated remote on/off switch and the Xanbus System Control Panel for monitoring and control from another location on the vessel. When sizing an inverter, add up the wattage of everything you plan to run simultaneously, not just the largest single load. Consider where the unit will mount, how it will ventilate, and how the cabling run to your battery bank affects your voltage selection.
