Signal for Heat pump
Posted: Wed Feb 25, 2026 12:04 pm
Hi,
Inverter FOX H3-10.0-E (+ Battery)
my installation company went bankrupt. So they didn´t finish the installation.
Battery and inverter and app are working.
But the installation company left before connecting to my heat pump.
My heat pump can receive a signal indicating that more electricity can now be used. It then heats up using the heating element to utilize the excess electricity.
I'm running a two-wire cable from the inverter to the heat pump.
And I know how to connect the heat pump.
But where do I get the signal from the inverter?
When I bought the system, I was told that this was possible.
In German, this connection is called the S0 bus.
Can anybody help?
Many thanks
Magnus
