[RE-wrenches] Xantrex XW4548 lifespan

[Jay]

Way too many variables to know 6 days to 6 years. 
When inverters get this old I tell people they have 2 choices. Run it until it dies or starts to have issues often leaving them without power ,running on a generator or replace on your schedule and product availability 

No right or wrong answer really.
