Strange discovery with my Morningstar controller, seems like I'm overdue for battery service by almost 43 billion days, or 11, 770 years, these batteries must be durable.

    LOL.  I'm a bit surprised it can count that high, though it looks like it's "only" ~4.3 billion days.

    Assuming 32 bit processor, max int would be 2^32=4,294,967,296 ...so you better get busy  >:)
    Off-grid.  
    Main daytime system ~4kw panels into 2xMNClassic150 370ah 48v bank 2xOutback 3548 inverter 120v + 240v autotransformer
