There has been a push to integrate a "scroll mode" to the Conext
Gateway. This could be left on a tablet 24 /7 and the user would just watch
the basic screens that the installer can easily program. I hope Schneider
will do this. It is similar to the scroll mode in the mppt-60 but would be
much better display than alpha numerics. The graphics in the Gateway are
very nice and can tell the heath of the system to a non-informed user very
quickly. And, no buttons to push if desired.

view the real time data for many parameters, and they are typically more

CC:  SUBJECT:[RE-wrenches] Internal BMS vs external capacity meter    
Hi
all,

A common question I see and have around lithium is figuring out SOC.


I have to assume that the internal BMS is as accurate as one can get.

That said, does anyone have real world data that compares accuracy of
internal BMS SOC to external SOC meters, such as bogart, Schneider, OB,
magnum?

The companies that list how to set up a external 3rd party SOC
meter have them set up in a way that seems unlikely to be that accurate,
especially in PSOC and in low SOC conditions. 

For most of my clients,
they don't want a computer/phone view only SOC meter.
Having a easy to read
and understand SOC meter on the wall is important to them. 

So wondering
if folks have
answers?

Thanks
Jay
