[RE-wrenches] FullRiver battery question

[Ray]

For your application, that battery seems like a great idea.  I had a rep 
from Michigan Energy Works drive all the way out to my off grid place in 
New Mexico back in 90s to demo that inverter. Seemed like a good idea, 
they just didn't have a good charge controller worked out for solar at 
144 vdc at that time.  I was actually considering their inverter to 
provide onboard job site power on a 144 vdc electric vehicle we had built.
