[TRNSYS-users] PV problem (type 94)

[David BRADLEY]

Leona,
   There is no output power from Type48 because the load on the inverter 
(an input) is always zero. Can you give me a little more context as to 
what you are trying to accomplish with your simulation? I might be able 
to make a better suggestion if I had a clearer picture of the objective.
Best,
  David
