[RE-wrenches] sol ark reliability question

[Mac Lewis]

Hi Jay,

Generally, Sol-Ark has been very good to work with for us.  We've done
about a dozen of them.  We did have an MCU swap for a parallel stacking
glitch.  I could tell it was a known issue because the diagnosis was
remote, took about 10 seconds and the shipping was about 2 days and has
fixed the issue.

My only gripe with Sol-Ark is the general weirdness of the generator
integration.  Not really much you can do to adjust or optimize, so this
could be better.  I suspect they will get this better over time.  I would
also like them to work to add a little timing bubble as parameters are
getting updated.  I think its confusing when you can't tell if a parameter
"stuck" or not.  A little visual feedback would be great.

Overall, very good to work with as a company, but Im still getting used to
their tech.
