Registration is not a condition of warranty. Your generator has a 3 year warranty from date of in-service. All you have to prove is when it was put into service/purchased.
The Energy Command 30 will need to be reprogrammed. It can be done at the Grand National Rally in Forest City later this month if you are going to be there? If not, the control panel will need to be sent in, reprogrammed and returned. I can email you the details when I'm back in the office next week. Please send me your email address.
