Deye + OCPP chargers

What Zerofy can do with Deye and OCPP chargers

In practice

• Zerofy adjusts the charging current of your OCPP 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 Deye home system (5–12 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 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.
• Many chargers switch off their own app or solar mode while an external OCPP backend is active (for example enercab, Growatt THOR, SolaX in its OCPP scene), so Zerofy takes over. Zerofy sets the power over OCPP but not the phases, so a three-phase charger needs about 4.1 kW of surplus (3×6 A) unless it switches phases by itself.

What Deye and OCPP chargers 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.

OCPP chargers: OCPP itself has no solar mode: since 1.6 it carries smart-charging profiles, so the backend sets the current limit and decides when to charge. Solar behaviour therefore comes from whichever system is the backend, or from the charger’s own meter-based mode.

Zerofy connects the two: it reads Deye production and controls your OCPP charger to match, together with your other devices in one app, with dynamic tariffs and forecast-based Smart mode.

Setting up Deye and OCPP chargers in Zerofy

1. Connect Deye

Zerofy connects to Deye Cloud with your Deye Cloud login and reads PV production, meter (consumption) and battery data.

1. Register your system in Deye Cloud (web or the Deye Cloud app).
2. In Zerofy, add an inverter, choose Deye and log in with your Deye Cloud credentials.
3. Configure the meters: the grid meter as main meter (bi-directional or consumption), production as a sub meter of type production.

2. Connect OCPP chargers

You enter Zerofy’s OCPP URL in your charger’s OCPP settings; Zerofy then acts as the backend and can start, stop and set the charging power.

1. Check that your charger supports OCPP 1.6 and lets you change the backend address.
2. In Zerofy, add an OCPP charger and copy the OCPP URL.
3. Paste it into the OCPP settings of your charger’s app or web page and wait for it to connect.

Good to know: Not every OCPP charger lets the owner choose the backend: some need the installer’s service tool (Alfen, ABB), some pick from a preset list (Peblar) or whitelist the address first (Smappee), and some offer no owner OCPP at all (Tesla Wall Connector, Ohme).

3. Turn on Autopilot

In Zerofy, open your OCPP 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 OCPP 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.

About Deye and OCPP chargers

Deye – Deye (Ningbo Deye Inverter Technology, Ningbo, China) is best known for low-voltage hybrid inverters such as the three-phase SUN-5K to SUN-12K-SG04LP3-EU, used with 48 V batteries. It also makes SUN-M60/80/100G4 microinverters (600–1000 W) for balcony and small rooftop systems. Monitoring app: Deye Cloud.

OCPP chargers – OCPP (Open Charge Point Protocol) is the open standard from the Open Charge Alliance for communication between a charger and a management system; version 1.6 from 2015 is the most widely used, in its JSON variant 1.6J. A charger can only be connected to one OCPP backend at a time. Products: Any charger with OCPP 1.6J and a freely configurable backend, e.g. Alfen Eve, KEBA KeContact P40, Charge Amps Halo, Autel MaxiCharger, enercab smart.
