Growatt + Alpha Innotec

What Zerofy can do with Growatt and Alpha Innotec

In practice

• Hot water is the simplest heat store: Autopilot can use the hot-water boost of your Alpha Innotec heat pump to heat water in hours with surplus.
• A heat pump draws roughly 1–3 kW while running, which a typical Growatt home system (2.5–10 kW) can cover on sunny days.
• Zerofy gets new Growatt data every 5 minutes. Heat pumps shouldn’t switch often, so set a minimum runtime in Autopilot.
• Zerofy also shows your Growatt battery, so you can see whether surplus goes into the battery or into the heat pump.
• If the PV-Ready contact is wired to your inverter as well, decide which system triggers the hot-water run so the tank isn’t heated twice; with Zerofy the boost follows your inverter’s live surplus from its cloud, without extra wiring.

What Growatt and Alpha Innotec 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.

Alpha Innotec: All alpha innotec heat pumps with Luxtronik 2.0 or newer are PV-Ready and SG-Ready: a potential-free contact from the inverter (or a relay) starts the heat pump, which then heats at full power up to the return-temperature limit and makes hot water up to the maximum flow temperature. alpha innotec doesn’t name specific inverters; any inverter or energy manager with a switching contact works.

Zerofy connects the two: it reads Growatt production and controls your Alpha Innotec heat pump to match, together with your other devices in one app, with dynamic tariffs and forecast-based Smart mode.

Setting up Growatt and Alpha Innotec in Zerofy

1. Connect Growatt

Zerofy connects to the Growatt cloud: you log in with your ShinePhone credentials.

1. Make sure your inverter is online and registered in the ShinePhone app.
2. In Zerofy, choose Growatt and log in with your ShinePhone username and password.

Good to know: Inverter data is supported; battery and meter data may only be partly available depending on the system. Battery control and using the battery in Autopilot are listed as coming soon for Growatt.

2. Connect Alpha Innotec

Zerofy reaches alpha innotec heat pumps through the myUplink cloud, the same connector used for NIBE, with your myUplink login; Autopilot controls the hot-water boost.

1. Register the heat pump (Luxtronik 2.1, current software) in the myUplink app.
2. Make sure your myUplink account has the subscription needed for remote control.
3. In Zerofy, connect myUplink and log in with your myUplink credentials.
4. Enable Autopilot (Solar or Smart mode) for the hot-water tank.

Good to know: Only heat pumps on myUplink (Luxtronik 2.1) can be reached; Luxtronik 2.0 units that use heatpump24 can’t. Zerofy steers only the hot-water boost, not room or flow temperature.

3. Turn on Autopilot

In Zerofy, open your Alpha Innotec heat pump, turn on Autopilot and choose Solar – or Smart to also use dynamic tariffs and forecasts. Set the priority, activation threshold and minimum runtime.

Dynamic tariffs

Zerofy can also run your Alpha Innotec heat pump on dynamic electricity prices (EPEX Spot or Nord Pool, e.g. Tibber or aWATTar) or on a fixed time-of-use tariff. Smart mode combines those prices with forecasts of your household consumption and your Growatt solar production.

About Growatt and Alpha Innotec

Growatt – Growatt (Shenzhen Growatt New Energy, China, founded 2011) makes string and hybrid inverters such as the MIN TL-X and MIN TL-XH series, the NEO microinverters and the NOAH 2000 balcony battery. Its own ecosystem, GroHome, adds the THOR wallboxes, APX HV batteries and the GroBoost heater controller. Monitoring app: ShinePhone.

Alpha Innotec – alpha innotec is a German heat pump brand of ait-deutschland in Kasendorf, Bavaria. Its heat pumps run on the Luxtronik controller; units with Luxtronik 2.1 connect to the myUplink cloud, older Luxtronik 2.0 units use heatpump24. Products: Air-to-water and brine-to-water heat pumps with Luxtronik 2.1 control (myUplink) or Luxtronik 2.0 (heatpump24).
