Jim, Sensata Technologies has bought Magnum Energy. And it appears, also another company called Dimensions. So the Site you care about (used to be www.magnumenergy.com <http://www.magnumenergy.com/>) is now http://www.magnum-dimensions.com <http://www.magnum-dimensions.com/>. The former will also re-direct you. There are several lines of inverter-only devices on the website, of which the CSW-series is only one. You need one that Complies with ABYC E11; that is, one that DOES NOT bond neutral to ground when on shore power, but does bond neutral-to-ground when operating in invert mode. Not sure the CSW model complies; pretty sure it does not comply, as it appears to be made as a stand-alone device with NEMA 5-15 receptacles, and not made for integration into an AC system. Suggest you contact Magnum Tech Support to discuss your requirements. The only contact info I have for tech support is <support@magnumenergy.com <mailto:support@magnumenergy.com>>. The "Contact Us" link shows several phone numbers for sales and marketing support that could probably help you. Jim Peg and Jim Healy aboard Sanctuary, currently at Ft.
