amanphoto 0 Report post Posted January 17, 2012 Does anyone know how many watts the 250CR Alternator is. I have the 2005 Volvo 5.7L engine. I'm putting in a big inverter and wanted to make sure that the alternator is big enough to power the appliances. Share this post Link to post Share on other sites
