For vessels not equipped with an uninterruptible power supply (UPS), professional installers often recommend including a dedicated inverter with onboard computer installations.

This is especially important if you intend to run an external CRT monitor (where the quality of electrical power is particularly critical), or if there are microwaves and other high in-rush current devices aboard.

Our top pick for laptop installations is the 300- watt, quasi sine wave inverter from Analytic Systems. The electrical noise generated by lesser units plagues many boaters due to interference with radios, autopilots, or other devices sharing the same batteries. There's also a 300-watt pure sine wave model available. For systems requiring more power we also carry 600 and 1,000-watt pure sine wave models. The extremely heavy input filtering and reliable, marine-grade design sets all of Analytic's units apart from other inverters we've seen. Every Q'Sine and PureSine model is available in versions designed to operate with 12-, 24-, or 32-volt battery systems.
