[RE-wrenches] Another SolArk issue, this time re Data Monitoring

[Christopher Warfel]

There is another advantage to being able to monitor w/o batteries 
initially. It allows data to be collected on how the facility uses 
energy which is much better in my opinion for sizing than an inventory 
and and hours assumed load study.
