[RE-wrenches] Trace SWs in Energy Management Mode

Indeed LBX can have the unintended consequence of charging during peak hours
if the loads draw the batteries down during that time.  This can be avoided
if you can control the loads so all or most do not operate during peak
hours.

PS:  The obvious logic is that if you can control the loads to operate
minimally or not at all during peak hours, you don't need inverters and
batteries anyway.

Thanks, I was thinking about using LBX, but the customer is really not too
excited about it.  And based on the manual, Energy Management Mode seems
like it fits the bill, but it doesn't seem to be going back into
stand-alone/inverter mode when the timer is supossed to turn off.

Hi Brian, 
LBX would be better for the way this customer is using the system, because
it only connects 
 to the grid when the batteries get low. Unfortunately, the timers do not
affect LBX, so charging 
may occur during the peak rate....or it may not :C) 

Rgds,
