Sungrow + Beny

What Zerofy can do with Sungrow 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.
• A typical Sungrow home system (3–10 kW) needs a sunny midday to reach the 4.1 kW three-phase minimum. Wired single-phase, the charger starts from about 1.4 kW but charges at no more than about 3.7 kW.
• Zerofy gets new Sungrow data every 5 minutes and adjusts accordingly. A minimum runtime and an activation threshold in Autopilot keep passing clouds from interrupting charging.
• Zerofy also shows your Sungrow battery, so you can see whether surplus goes into the battery or into the car.
• 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 Sungrow and Beny offer on their own

Sungrow: Sungrow sells its own AC chargers (AC007E-01, AC011E-01, AC22E-01), whose Eco mode charges on surplus when the charger is paired with a Sungrow hybrid inverter via WiNet. Larger setups with up to three chargers need the Sungrow iHomeManager; third-party wallboxes are not controlled by iSolarCloud itself.

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 Sungrow 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 Sungrow and Beny in Zerofy

1. Connect Sungrow

Zerofy connects to your Sungrow system through the iSolarCloud cloud, using your iSolarCloud login.

1. Make sure your Sungrow inverter is online and registered in iSolarCloud.
2. Add Sungrow in Zerofy and log in with your iSolarCloud credentials.

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 Sungrow solar production.
