TSUN + Easee

What Zerofy can do with TSUN and Easee

In practice

• Zerofy adjusts the charging current of your Easee charger but doesn’t switch phases. On a three-phase connection, solar charging needs at least about 4.1 kW of surplus (6 A × 3 × 230 V); on a single-phase connection about 1.4 kW.
• Many TSUN systems are small (typically 0.8–3 kW). A balcony system rarely produces the 1.4 kW needed to start charging, so solar charging works best with larger TSUN installations; Smart mode can still move charging to the cheapest hours.
• Zerofy gets new TSUN data every 5 minutes and adjusts accordingly. A minimum runtime and an activation threshold in Autopilot keep passing clouds from interrupting charging.
• If your car is connected to Zerofy too, turn on Autopilot for either the car or the charger, not both.
• Easee needs at least 6 A to start, which is about 1.4 kW on one phase and 4.1 kW on three. If the charger’s phase mode is set to automatic, Zerofy warns you and plans with the three-phase minimum until Easee reports single-phase charging; a fixed single-phase setting lets charging start from about 1.4 kW, but caps it at about 3.7 kW.

What TSUN and Easee offer on their own

TSUN: TSUN offers no EV charger and no surplus-charging function. An 800 W balcony system also stays below the about 1.4 kW a charger needs at its 6 A minimum.

Easee: Easee’s own solar charging needs an Easee Equalizer on the site (the P1/HAN version reads the smart meter, Equalizer Amp measures with current sensors) and Easee as site operator. The Easee app then offers “Surplus only” and “Limited grid usage”; it does not read any inverter directly.

Zerofy connects the two: it reads TSUN production and controls your Easee charger to match, together with your other devices in one app, with dynamic tariffs and forecast-based Smart mode.

Setting up TSUN and Easee in Zerofy

1. Connect TSUN

Zerofy connects to the TSUN cloud with your TSUN Smart login and reads your inverter data.

1. Register your system in the TSUN Smart app.
2. In Zerofy, add an inverter, choose TSUN and log in with your TSUN Smart credentials.

Good to know: Only TSUN Smart accounts work (inverter IDs starting with Y); TSUN Home accounts are not supported. Battery and meter data are only partly available, depending on the system.

2. Connect Easee

Zerofy logs in to your Easee account and starts, stops and sets the charging current through the Easee cloud.

1. Make sure your Easee charger is online and added to your Easee account.
2. In Zerofy, add an Easee charger and log in with your Easee account.

Good to know: Data synchronisation depends on how often the Easee cloud updates, so live values in Zerofy can lag behind the charger.

3. Turn on Autopilot

In Zerofy, open your Easee charger, 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 Easee charger 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 TSUN solar production.
