[RE-wrenches] System Monitor for HV Off Grid System?

[Ray]

I actually saw one of those once, they did a presentation. Seemed like a 
good idea, but they never had a good answer on charge controllers and 
other equipment.  The E meter can work at higher voltages.  I used them 
with 144 vdc battery banks before.
