I have a 3.68 kW PV system and would like to use it to power a modulating heat pump of about 5 - 10kW output in such a way that during the day it only draws as much power as would otherwise be exported.
One installer has said you can do this with an Eddi. However from example 14 here https://myenergi.com/wiki/eddi/application-examples/ it is clear this is in an on-off fashion so does not modulate the heat pump output at all.
I already have a PV diverter box which could be easily modified to produce e.g. a 0-10V demand signal or possibly a digital output for a suitably receptive heat pump.
Can anyone tell me if there are heat pumps that are controllable by an external signal in this way and/or a suitable commercial PV controller?
TIA, Chris
