TSUN + Beny

What Zerofy can do with TSUN and Beny

In practice

• Zerofy adjusts the charging current of your Beny 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.
• The standard load-balancing kit is not the same as the Solar DLB box: only the solar version unlocks the PV and Hybrid modes. Via OCPP, Zerofy sets the charging power but not the phases, so on a three-phase BENY charging needs at least 6 A per phase, about 4.1 kW of surplus.

What TSUN and Beny 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.

Beny: BENY’s own solar charging needs its Solar DLB box with current clamps at the house connection, configured in the Z-BOX app. It offers “PV” mode (keeps grid draw close to 0 A), “Hybrid” mode (solar plus grid within the DLB limit) and “Full speed”; it does not talk to the inverter.

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

Setting up TSUN and Beny 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 Beny

Zerofy has a dedicated BENY entry in the app, which connects via OCPP; Zerofy can then start, stop and set the charging power.

1. In Zerofy, add a BENY charger and copy the OCPP URL.
2. Paste it into the OCPP settings of your charger’s configuration app.
3. Wait until the charger connects to Zerofy.

3. Turn on Autopilot

In Zerofy, open your Beny 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 Beny 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.
