[QUOTE="binky, post: 374992, member: 490"] Power One is part of ABB group, not famous for being cheap sh1te. It converts from dc to ac using high frequency galvanic isolation. Power one used to have a function whereby you could re-set the frequency it operates at to gain a slight increase in efficiency, they are normally set to a range which is inaudible. If the inverter is somewhere you are unlikey to hear it, changing this setting will change the frequency of operation, which may solve your heater issue. I tried this on my own inverter and could hardly hear it from 2 feet away. [/QUOTE]
