SL Energy + go-e

What Zerofy can do with SL Energy and go-e

In practice

• Zerofy can switch your go-e Charger between one and three phases. Solar charging can therefore start at about 1.4 kW of surplus (6 A on one phase) and move to three phases once the surplus passes about 4.1 kW.
• A typical SL Energy home system (3–12 kW) reaches the 1.4 kW single-phase minimum on most bright days; three-phase charging from about 4.1 kW needs a sunny midday or a larger system.
• 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 go-eCharger charges from 6 A, about 1.4 kW on one phase and 4.1 kW on three. Zerofy charges single-phase up to about 3.7 kW of surplus and switches to three phases above that; go-e lists automatic phase switching for Gemini models and HOME V3, so older HOME units stay on the phases they are wired with.

What SL Energy and go-e 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.

go-e: go-e’s own route to surplus charging is the go-e Controller, which measures the house connection with six current sensors and works with any inverter brand, including automatic 1/3-phase switching. Without the Controller, go-e relies on external energy managers through its open API, Modbus TCP or OCPP.

Zerofy connects the two: it reads SL Energy production and controls your go-e Charger to match, together with your other devices in one app, with dynamic tariffs and forecast-based Smart mode.

Setting up SL Energy and go-e 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 go-e

Zerofy uses the go-e Cloud HTTP API with your charger’s serial number and API token, sets the charging current and switches between one and three phases.

1. Update the charger to firmware 052 or later and the go-e app to 2.3 or later.
2. In the go-e app, go to Internet → Advanced Settings and turn on the Cloud HTTP API.
3. Copy the API token shown there and enter it in Zerofy together with the charger’s serial number.

Good to know: Supported are Gemini 2.0 (serial 400000+), Gemini (200000–399999) and HOME (050000–199999).

3. Turn on Autopilot

In Zerofy, open your go-e 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 go-e 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.
