Precise balance of demand to PV output

Precision power managment of Solar PV renewable output.

The data below was taken from Deer-n-Dexter farm, on 22 May 2012.
The EMMA being used is an EMMA SP15/60 3G GVS. The solar PV system is 20kW.

The two graphs below show the Deer and Dexter system working perfectly, holding the entire site load exactly in line with the PV output. The “shark teeth” are where heavy electrical plant (freezers) are switching on and off and EMMA takes a few seconds to respond.
