Growatt + PHNIX

What Zerofy can do with Growatt and PHNIX

In practice

• Autopilot isn’t available for PHNIX yet, so Zerofy won’t run your PHNIX heat pump on solar surplus automatically. You can see Growatt production and PHNIX in one app and adjust the room temperature and flow temperature from there.
• Because Zerofy does not run PHNIX units on surplus automatically, put the heating or pool-heating window into the middle of the day with a schedule; pool heat pumps run mainly in summer, when midday PV output is highest.

What Growatt and PHNIX offer on their own

Growatt: The GroBoost heater controller sends surplus solar to immersion heaters, adjustable from 0 to 10.8 kW across three outputs (three 3.6 kW single-phase heaters or one three-phase heater). Growatt’s own product pages don’t mention control of heat pumps or SG Ready.

PHNIX: PHNIX’s “PV Ready” function lets the heat pump adjust its compressor frequency to the available solar power, controlled by a home energy manager or, if there is none, by PHNIX’s own Smart Meter. A “Spot Time” mode works with grid prices (target temperature, maximum frequency, six daily timers), and the Heco series also has an SG Ready interface.

Zerofy connects the two: it reads Growatt production and controls your PHNIX heat pump to match, together with your other devices in one app.

2. Connect PHNIX

Zerofy connects to the PHNIX cloud with your PHNIX app login and shows the heat pump’s live status; you can set the room temperature and the water circulation temperature from Zerofy.

1. Connect the heat pump to the internet and register it in the PHNIX app.
2. In Zerofy, add PHNIX and log in with your PHNIX account credentials.

Good to know: Zerofy’s Autopilot does not yet run PHNIX heat pumps on solar surplus or dynamic prices; control from Zerofy is manual or by schedule.
