SolarEdge + go-e

What Zerofy can do with SolarEdge 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 SolarEdge home system (3–10 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 SolarEdge 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 SolarEdge 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 SolarEdge and go-e offer on their own

SolarEdge: SolarEdge sells its own EV charger, controlled from the mySolarEdge app. With the SolarEdge ONE Controller (inverter firmware 4.22 or later), mySolarEdge can instead run one third-party OCPP 1.6J charger with Excess Solar charging: MENNEKES AMTRON, Wallbox Pulsar Max/Plus/Pro, Alfen Eve S-line/Pro-line or ABB Terra AC. Only one charger can be used at a time.

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 SolarEdge 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 SolarEdge and go-e in Zerofy

1. Connect SolarEdge

Zerofy connects to SolarEdge’s monitoring cloud with the same login you use for the SolarEdge Monitoring website or the mySolarEdge app.

1. Make sure your SolarEdge inverter is online and your account has the Owner role on the site.
2. Add a new SolarEdge device in Zerofy.
3. Log in with your SolarEdge Monitoring / mySolarEdge credentials and follow the on-screen prompts.

Good to know: Your account needs the Owner role, which the installer usually assigns to the system owner during setup; ask your installer if you don’t have it. Battery and meter data depend on how your system is configured.

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 SolarEdge solar production.

About SolarEdge and go-e

SolarEdge – Israeli company (Herzliya) known for inverters with a power optimizer on every module. Homes typically have a SolarEdge Home Wave single-phase or Home Hub three-phase inverter with optimizers, often with a SolarEdge Home Battery and SolarEdge Home smart-energy accessories. Monitoring app: SolarEdge Monitoring / mySolarEdge app.

go-e – go-e is an Austrian charger maker. The current go-eCharger Gemini 2.0 (11 or 22 kW) has documented local and cloud APIs, MQTT, Modbus TCP, a freely configurable OCPP backend and an eSIM; according to the data sheet it is not approved for the Netherlands, France or Italy. Products: go-eCharger Gemini 2.0, Gemini, HOME.
