Modern appliances and electronics call for modern power options.
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
