Hi there. I’m sorry if this question has been asked before, but I’m guessing every installation is different so want to be absolutely sure I get what I need.
I have a property with a 4kW solar PV array and a 15.2kW Ochsner ground source heat pump. I would like to get a better handle on my energy generation and consumption (particular the GSHP) patterns in order to optimise my usage, and give me better data for making decisions about energy suppliers/tariffs. Ideally, as I don’t currently have a solar PV diverter, I’d also like to investigate ways of diverting excess generation to the immersion in the DHW tank to reduce the amount of work the GSHP needs to do.
The incoming feed from the external meter box enters the house on an outside wall and goes on to feed the main consumer unit. However, the solar PV inverter, generation meter (no export meter), and consumer units for the GSHP and PV are all located together (as per the photograph). The GSHP itself is about 6m away from this location, and consists of the heat pump and two buffer tanks (UFH/Rads and DHW) with mixing valves.
What I’m trying to get my head round is what I would need for this set up. I was initially assuming an emonPi Solar PV Bundle installed near the solar inverter/incoming feed, but I’m not sure whether this would be sufficient (and whether I’d need an optical pulse sensor on the generation meter), and how I would then address the PV diversion.
Can anyone help me out please?
Thank you in advance.
