Mod­ern ap­pli­ances and elec­tron­ics call for mod­ern power op­tions.

Boating - - FEATURES -

Nearly ev­ery ap­pli­ance you plug into an out­let op­er­ates on solid­state “brains,” which are sen­si­tive to power fluc­tu­a­tions and cur­rent fre­quency. True sinewave in­vert­ers are par­tic­u­larly im­por­tant to­day for run­ning com­put­ers, smart TVs, re­frig­er­a­tors, and even cof­fee mak­ers and mi­crowaves due to their sen­si­tive elec­tronic com­po­nents. Even if your old mod­i­fied sine-wave in­verter is still crank­ing out 110 volt­age, it might be killing your flat-panel TV or mi­crowave. For this in­stal­la­tion, we’re as­sum­ing you al­ready have an in­verter, al­ready know your load and have ad­e­quate di­rect-cur­rent power on board to power the load in the ab­sence of shore power or a genset. But keep in mind, a cof­fee maker will likely need 200 watts of power, a blender 1,000 watts and a mi­crowave 1,200 watts. You might need to run these while the fridge is run­ning, so the 3,000watt Xantrex Free­dom SW 3012 true sine-wave in­verter is a likely choice for cruis­ers with such de­mands. — Randy Vance
