Deye + Zaptec
Deye + Zaptec: solar surplus charging from about 1.4 kW thanks to phase switching, plus dynamic tariffs. Set up in the Zerofy app, no extra hardware.

Automatically charge your EV with surplus solar power from your Deye system. Solar surplus charging made easy.
Dynamic Tariffs
Optimize for electricity prices. Charge or run devices when rates are lowest, and use solar when prices are high.
Cloud Integration
No hardware required. Connect your Deye and Zaptec via cloud APIs in minutes.
Deye + Zaptec: TL;DR
Yes, Deye and Zaptec work together in Zerofy. Zerofy reads your Deye system through Deye Cloud and controls your Zaptec charger through the Zaptec cloud. With phase switching, solar charging starts from about 1.4 kW of surplus. Smart mode also follows dynamic electricity prices and solar forecasts. No extra hardware needed.

In practice
- Zerofy can switch your Zaptec 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 Deye home system (5–12 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 Deye 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 Deye 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.
- Ask whoever set up the charger to make you site owner in the Zaptec portal or to grant the permissions; otherwise Zerofy can only switch charging on and off instead of following the surplus. With phase switching the Go 2 starts at about 1.4 kW on one phase; on three phases it needs about 4.1 kW.
What Deye and Zaptec offer on their own
Deye: Deye’s own SUN-EVSE11K01/22K01-EU-AC charger can be set up in the hybrid inverter’s Smart Devices menu with a “Solar energy only (SOC>95%)” time slot. This needs a Smart TX module on the inverter for the LoRa link, and not every Deye hybrid supports it.
Zaptec: Since June 2026 Zaptec offers its own solar charging in the Netherlands, Belgium, Germany, Switzerland and Luxembourg for Go, Go 2 and Pro. It needs a Zaptec Sense (Generic or P1) that detects local production, a Home installation with up to three chargers and a TN grid; the app then offers “Surplus + grid” and “Surplus only”.
Zerofy connects the two: it reads Deye production and controls your Zaptec charger to match, together with your other devices in one app, with dynamic tariffs and forecast-based Smart mode.
Setting up Deye and Zaptec in Zerofy
1. Connect Deye
Zerofy connects to Deye Cloud with your Deye Cloud login and reads PV production, meter (consumption) and battery data.
- Register your system in Deye Cloud (web or the Deye Cloud app).
- In Zerofy, add an inverter, choose Deye and log in with your Deye Cloud credentials.
- Configure the meters: the grid meter as main meter (bi-directional or consumption), production as a sub meter of type production.
2. Connect Zaptec
Zerofy connects with your Zaptec portal login and controls charging, current and phases through the Zaptec cloud.
- Make sure your Zaptec charger is online and registered in the Zaptec portal.
- In Zerofy, add a Zaptec charger and enter your Zaptec portal credentials.
Good to know: Only the site owner in the Zaptec portal may change current and phases. Without that permission Zerofy can only start and stop charging, and the app tells you so. Charging sessions only appear in the history after the car has been unplugged.
3. Turn on Autopilot
In Zerofy, open your Zaptec 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 Zaptec 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 Deye solar production.
