For even more detailed information on inverters, go see Phred Tinseth's Inverter Poop Sheet on the subject. Phred will give you a lot of great (somewhat opinionated) information on the whole process of choosing an inverter. Well worth your time if you're thinking of installing one! Also, stop by and read some of his other Poop Sheets... Phred is a fine source of information and he has many articles on a variety of RV related topics. A very useful resource for all you Rvers out there!
