SL Energy + Beny

What Zerofy can do with SL Energy 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 SL Energy home system (3–12 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 SL Energy 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 SL Energy 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 SL Energy and Beny offer on their own

SL Energy: SL Energy offers its own smart wallbox as part of the iShare-Home package, and the Smart M app lists charging piles among the devices it manages. SL Energy doesn’t publish details on solar-surplus charging or third-party wallboxes.

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 SL Energy 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 SL Energy and Beny in Zerofy

1. Connect SL Energy

Zerofy connects to the SL Energy cloud: you log in with your SL Energy monitoring account (the one you use in the Smart M app).

1. Make sure your inverter is online and registered on the SL Energy monitoring platform.
2. In Zerofy, choose SL Energy and log in with your SL Energy account to grant access.

Good to know: For the battery, Zerofy supports forced charging but not switching the battery mode.

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 SL Energy solar production.
