Wayne:



I have one Deka Duration D5300 connected to an Outback VFXR.  It seems to
be working OK.  There is no generator so I can’t comment on how that would
work.



The set-points as advised by Deka are evolving so keep an eye on their
integration sheets.

*Subject:* [RE-wrenches] Pairing OB with Lithium



We have an off-grid customer who has a 10KW array and 2 - VFXR3648's, 2 -
FM 80's and dying lead acid batts.



I'm looking for advice on pairing something in the range of +/-5 kWh of
Lithium (preferably LFP).

I have not yet paired OB with lithium. Compatibility and Reliability are my
goal.

What has worked best for you?



Your experience and advice are greatly appreciated.
