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.

ELITE Control

The ELITE is the latest addition to the EMMA product family. While we consider it to be the Elite of power diversion and monitoring it is in fact EMMA's little sibling or as we call it EMMA lite.

EMMA with Export Control

EMMA with EC allows for installs to have a greater renewable output than the Max Export Capacity (MEC) on site by diverting excess energy to heat.
