[TRNSYS-users] Without grid simulation

[David BRADLEY]

Tri,

   There are a number of different ways that you can do this. The method 
will depend on which battery and battery controller models are being 
used and even more specifically which /modes /of the battery and battery 
charge controller you are using. In general, look for ways of setting up 
the controller so that it does not go into a "charge battery from grid" 
mode. Then you can interpret the "grid power needed" output instead as a 
"load unmet" condition.

kind regards,

  David
