The inverter is a Viltron MultiPlus Phoenix 3KW, about as sophisticated as you get for this sort of application, I think, and its manual is quite clear about what sort of efficiency and management power loss to expect . My problem was that the reality did not match the theory, in spite of all my checks and consultations. Nothing from Viltron ever gave a reasonable explanation.Martinhttps://www.blogger.com/profile/08084401790316697529noreply@blogger.comtag:blogger.com,1999:blog-2576670202526573146.post-23638156280853940812016-05-11T19:54:24.675+01:002016-05-11T19:54:24.675+01:00Re Inverters - all of them draw a certain amount o...Re Inverters - all of them draw a certain amount of power even with no load. It's what is needed to run the internal circuitry. This can be anything from about a third of an amp (for small portable units), to one amp or more for large units. This is what kills your batteries, rather than the intermittent current needed to actually run a fridge. Some of the more sophisticated inverters have a "seek" mode where they will monitor the output to see if there are any loads, and if not, they shut down and just check every few seconds. Once a certain minimum load is seen they restart full output. for This would be O.K. for a mains fridge with a simple dial type thermostat, but probably not for newer ones with electronic controls.<br /><br />As for running TV's etc. on "12 volts" - do make sure that this means "up to 15 volts" or damage can occur when the engine or battery charger are running. If your TV model is specifically designed for mobile use you should be OK, but just making up a lead to replace a dedicated mains supply is not a good idea (and will almost certainly void your warranty).Dave Wardnoreply@blogger.com
