I've got an 800 watt Cobra MSW inverter in my truck, and when a moderate load was put on it (two laptops and a router) the RFI was bad enough that even my 2 meter FM radio and weather radio (typically noise-tolerant bands/mode) were severely degraded. It has a vertical form factor though, making it not as convenient for mobile use. Of the MSW units, the Tripp Lite had the obvious best characteristics.
Modified sine vs pure sine plus#
Xantrex XPower 1750 Plus MSW 1500 W continuous $230 Tripp-Lite PowerVerter PV-1250FC MSW 1250 W continuous $270 No-load current draw and efficiency are important factors to consider, as they affect battery life. Too much over-sizing can be costly, and it is smarter to buy the best small inverter than the largest cheap one you can find. It is my suggestion that you look for a good quality inverter that matches your load requirements. While MSW inverters can work at an Amateur Radio station, it is more likely that pure sine wave inverters will emit little or no interference, and attached electronic equipment will be happier. The pure sine were clearly the winners when looking at the outputs (the article shows the oscillscope traces).
Modified sine vs pure sine pdf#
I have a PDF copy of the article but it's too large to attach here. The April 2009 issue of QST magazine has a technical review of pure sine and modified sine wave power inverters.
