[RE-wrenches] Battery charging problems

[Chris Daum]

 Dear people:  

I have an off-grid customer who has, in his system, a Magnum MS4448 and 16
of the Rolls S550 batteries, a Kohler generator (and Trimetric meter and
other components).  He upgraded his batteries this past March, and since
he's installed his new batteries, the generator is running 'rough'.  He's at
a great distance from our shop so a local business helps him from time to
time. They believe that the "batteries are too  powerful for the 8.5 kw
generator" and recommended  running it at 50 percent charge control. After 3
hrs run, it seems to help but will mean more run time for his generator (and
hence, use more fuel).  Have you ever heard of anything like this?
Everything ran fund before the battery upgrade.

Thanks for your input!

Best,

Chris Daum
