Solar Energy Diversion / Dumping
 

THE SOLUTION:

We designed a simple logic program to primarily control the priority switching/cycling of heating loads during periods of high solar energy production because use of the energy generated is preferred over non use or feedback to a grid tied system. The base controller model provides up to four independent outputs, and up to 10 outputs are available on the larger controller. There is potential to upgrade to a further 6 outputs depending on your controller requirements.

 

A trigger output from the solar inverter is used to initiate the load cycling which can step forwards/backwards in a priority sequence based on time periods or loads demands from feedbacks in the field (eg an underfloor heating thermostat is calling for heat, and  a hot water tank is calling for heat - it will prioritise the H/W untill it is at temperature and then step to the undefloor heating and then cycle between the two to maintain temps using the priority logic based on feedback from the loads (via thermostats or current switches)

 

Incorporates auxillary control options from field devices.
