clarksgocamping Report post Posted June 20, 2021 we own a 2000 safari zanzibar since new. we have a 7.5 onan quiet diesel generator, 2000w inverter and 6 6v house batteries. we have fried several small appliances while using the inverter. 1 warming blanket 2 heating pads, a tooth brush charger, and hair curler. most of this on a particular outlet. we have used computers and other electronics with no problems. any ideas?

rossboyer Report post Posted June 20, 2021 Many resistive devices do not tolerate the output of an inverter well: warning blanket, heating pads and hair curler. Don’t know about tooth brush though. Share this post Link to post Share on other sites

The units do affect a number of the newer appliances and highly resistivity types of equipment. Had to replace our 2500 series Modified sine wave unit 4 years ago because it was the pest option for us rather then having it repaired. When with the pure sine wave model. They work much better, The biggest job was rewiring the coach electrical system; because the new units do not come with the 2 internal circuit beakers used to power the microwave and the entertainment circuits on our coach.

Yes Rich is right about the PSW vs a MSW inverter. Many of the newer appliances can't tolerate the abrupt change from positive to negative as a MSW produces. Pure sine wave is much closer simulation of the power grid generator cycle. The above images is a visual of what the incoming power looks like to your appliances.
