[RE-wrenches] Lithium batteries

[Sindelar Solar]

Howie,

I have now installed three Blue Ion systems (2 x 16 kwh and one 48kwh) 
and am very pleased with them. It's a complete package with clear 
instructions, all parts labeled, good technical support, and presents 
very well to the client when installed. BMS info is accessed online 
through the included and pre-programmed E-Gauge, which displays both BMS 
and consumption data. The BMS manages all charge functions; the 
inverters and controllers are overridden. I have only used them as 
upgrades to existing off grid systems with Magnum and Outback VFX 
hardware, but have an XW installation planned for early August.

Allan
