I was really bummed-out with DC-to-AC power inverters with so-called "Modified-Sine-Wave (MSW) outputs. Either the attached loads (mostly inductive or motorized equipment) would hum loudly and become excessively hot during operation, as well as struggle to even run at full, rated output simply due to the higher-order harmonics present in such inverters' outputs, not to mention having occasionally caused actual equipment damage with MSW output power.
But thanks to my new ExpertPower AC-to-DC power inverter with its truly honest-to-goodness low-frequency (NOT high-frequency) Pure-Sine-Wave output, even my most demanding loads, such as a 10,000 BTU window unit A/C, run like a champ despite large inrush currents while the A/C compressor is starting-up. Just try and pull that stunt with an "el-cheapo" MSW inverter with its high-frequency "pretend sine-wave" output and it's literally hello 'snap, crackle and POP!'
But wait, it gets even better yet. When my ExpertPower equipment arrived, I discovered that its Display Remote Controller panel was totally DEAD. While certainly a little disappointing for me, I was definitely most pleased with the fact that Customer Service shipped a new controller to me; they had my inverter up-and-running just 2 days later because they shipped a new controller unit to me via 2-Day air at NO additional charge whatsoever! I know just who to turn to for all of my future power conversion needs. Kudos for a first-class job-Keep up the good work and team-effort!
