Deye Copilot Complete Guide: Configure and Optimise Your Solar Installation

Your Solar Installation Can Become 100% Autonomous and Intelligent

Imagine a solar installation that manages itself, knows exactly when to charge your batteries at the cheapest time, when to use energy from the grid or from your panels, and makes all these decisions automatically while you sleep. That's exactly what Deye Copilot EMS does.

If you have a Deye hybrid inverter with storage batteries, you already have the perfect equipment. Now, with Deye Copilot, you can make your installation truly smart. No more wondering whether to charge your batteries at night or save them for tomorrow: artificial intelligence decides for you.

"Deye Copilot EMS is like having an energy expert working for you 24 hours a day, analysing electricity prices in real time and automatically controlling your installation so that you never pay too much for your electricity."

What exactly is Deye Copilot EMS?

EMS stands for "Energy Management System". But forget the technical jargon: Deye Copilot EMS is simply the intelligent brain that automatically controls your solar installation.

Here's what it does for you, without you having to think about it:

• It learns your habits: how much you consume in the morning, in the evening, at the weekend
• It monitors the weather: It knows whether tomorrow will be sunny or cloudy
• It knows the rates in real time: off-peak hours, peak hours, dynamic rates
• It manages your batteries intelligently: when to charge them, when to use them, when to preserve them
• It optimises every penny: selling to the grid when it's profitable, buying when it's cheap

Why you MUST activate Deye Copilot on your installation

You've invested thousands of pounds in solar panels, a Deye hybrid inverter and storage batteries. But without Copilot EMS, your installation is only operating at 60% of its potential.

Prerequisites: What Do You Need Before You Begin?

Before configuring Deye Copilot EMS, make sure you have:

1. A Deye hybrid inverter (all models are compatible: 5kVA, 8kVA, 10kVA, 12kVA, etc.)
2. Connectedstorage batteries (Pylontech, Delong or any other compatible brand)
3. The Deye Cloud app installed on your smartphone (version 3.2.0 minimum)
4. Your installation connected to Wi-Fi and functional in the application
5. Your electricity rates (EDF, Engie, Luminus bill, etc.)

✅ If you tick all these boxes, you're ready to go! Let's move on to the step-by-step configuration.

Step 1: Check that your installation is ready

Before requesting Copilot EMS activation, a quick check is required. Your installation must be correctly configured in the Deye Cloud application.

✅ Verification Checklist

1. Open the Deye Cloud application on your smartphone
2. On the home page, you should see your installation (often called "Plant" or whatever name you have given it)
3. Check that the data is displayed: Solar production, Consumption, Battery status (SOC %)
4. If everything is displayed correctly, it means that your Deye inverter is communicating properly with the application

🎯 If you see real-time data, you can proceed to the next step. Otherwise, check your Wi-Fi connection or consult our troubleshooting guide.

Step 2: Configure Your Electricity Rates (The Most Important Step!)

This is THE crucial configuration. Without this information, Deye Copilot EMS cannot make intelligent decisions. It absolutely needs to know how much electricity costs at each hour to know when it is profitable to:

• Charge your batteries from the grid (during cheap off-peak hours)
• Use your batteries (during peak hours when electricity is expensive)
• Sell your surplus to the grid (if the buy-back price is attractive)

Where can you find the pricing settings?

There are two ways to access them in the application:

Method 1 (the simplest): On the home page of your installation, tap directly on the area where the import/export price gauges are displayed.

Method 2: Go to Advanced Settings > Tariff Type

Choose the Tariff Type: Flat Rate or Dynamic?

You have two options depending on your electricity contract:

🔹 Option A: Flat Rate (Peak Hours/Off-Peak Hours)

This is the most common option in France and Belgium. Choose this option if:

• You have a subscription with off-peak and peak hours (such as EDF, Engie, Luminus)
• Your electricity price is the same throughout the day (single tariff)
• You have different rates at weekends

📋 How to Set Up a Flat Rate Step by Step

1. Select "Flat rate" from the menu
2. Press "Add a time segment"
3. Create your first segment: Off-peak Week
   • Segment name: "HC Week" (or whatever you want)
   • Start time: for example, 22:00
   • End time: for example, 06:00
   • Purchase price (Import): Check your bill! For example, £0.18/kWh
   • Selling price (Export/Injection): If you resell, enter the rate (e.g. €0.10/kWh), otherwise enter 0
   • Days: Tick Monday, Tuesday, Wednesday, Thursday, Friday
   • Confirm
4. Create the second range: Peak hours during the week
   • Same procedure, but with peak hours (e.g. 06:00 to 22:00)
   • Higher purchase price (e.g. £0.25/kWh)
5. Don't forget the weekend!
   • If your rates are different on Saturdays and Sundays, create specific segments

💡 Pro tip: Be ultra-precise! Take your electricity bill and note down the prices to the nearest cent. Every cent counts for the AI calculations. The more accurate the information, the more you save.

🔹 Option B: Dynamic Tariff (For Spot Pricing Contracts)

This option is for pioneers! Choose it if you have a contract with a supplier whose prices change hourly according to the market (such as Tibber, certain Engie Pro contracts, etc.).

📋 Dynamic Pricing Configuration

1. Select "Dynamic Pricing"
2. The application will ask you to link your supplier account via an API key
3. Go to your energy supplier's customer area
4. Retrieve your API key (often found in the advanced or developer settings)
5. Copy it into the Deye Cloud application
6. Confirm the connection

✅ Once the link is established, Deye Copilot automatically retrieves prices in real time. You don't need to do anything else!

Also configure the feed-in tariff (if you sell your surplus): Choose between "Fixed subsidy" (constant price) or "Dynamic tariff" (variable price).

Once your rates are configured, press "Next" or "Confirm".

🎉 Congratulations! You have just given Deye Copilot EMS the ability to see the electricity market. It is now ready to be activated.

Step 3: Request Activation of Deye Copilot EMS

Now that your tariffs are perfectly configured, it's time to wake up the artificial intelligence! Deye Copilot EMS is activated via a request made directly in the application.

🚀 4-step activation process

1. Access the Activation Request

• Return to the home page of your installation in Deye Cloud
• Press the Menu button at the top right (three small dots)
• Select "Apply for Deye Copilot"

2. Accept the Terms of Use

• An introduction page will open
• Read the information
• Tick "Agree to Terms"
• Confirm

3. Await Approval (1-2 Business Days)

Once your request has been submitted, the Deye team must review it manually. It's not instantaneous, but it's worth the wait!

• ⏱️ Usual timeframe: 1-2 business days
• 📧 You will receive a notification in the message centre of the Deye Cloud app
• ✅ A new "Copilot" icon will appear on the home page

4. Activate the "Deye Copilot" Control Mode

Once approval has been received (you will see the message "Deye Copilot is Enabled!"), there is one last step to give control to the AI:

• Go to the home page of your installation
• At the bottom of the screen: "Control Mode"
• By default, it is set to "Manual Mode"
• Tap on it and select "Deye Copilot"

🎊 That's it! Deye Copilot EMS is now the official pilot of your energy system. It will start analysing your data and applying its optimisation strategy.

⏳ Important note: The AI needs a few days to learn your consumption habits. Do not be surprised if the decisions seem cautious during the first few days. After 5-7 days, Copilot will be fully operational and optimised for your situation.

Step 4: Deye Copilot EMS Advanced Settings (To Go Further)

Your Deye Copilot EMS is now active and already using a highly effective default strategy. But you can go even further! The advanced settings allow you to fine-tune the AI's behaviour to your specific needs.

To access them: Home page > "Advanced Settings"

1. AI Strategy: What Is Your Main Objective?

This is the strategic brain of Copilot EMS. You give it its main mission. Three options:

🎯 Our advice: Start with "Maximise self-consumption". This is the safest and most profitable strategy in 99% of cases for residential installations.

2. Battery Optimisation: Take Care of Your Investment

Your batteries are an investment of several thousand pounds. This menu allows the AI to take into account the "wear and tear cost" and preserve their lifespan.

🔧 Settings to configure

"The cost of my battery cycles..." control: Enable this option! The AI will be gentler on your battery and avoid charging/discharging it for minimal gains.

Battery cost: Enter the total price you paid for your batteries (e.g. £5,000).

Battery cycle: Number of cycles guaranteed by the manufacturer (usually 6,000 cycles for Pylontech, Marstek, etc.)

Battery Capacity: Total capacity in kWh (e.g. 22 kWh)

💡 Why is this important? With this information, Copilot EMS calculates that a full cycle costs approximately £0.83 (£5,000 ÷ 6,000 cycles). It will only charge/discharge the battery if the savings exceed this cost. The result: your battery lasts 15-20 years instead of 8-10 years!

3. Peak Shaving: Avoid Power Overruns

This setting is useful if your electricity contract charges penalties for consumption "peaks" (exceeding the contracted power).

Control Mode: Only activate this if applicable
Peak Smoothing SoC: Battery level (in %) kept in reserve to manage a peak

🎯 Our advice: For most domestic contracts in France and Belgium, this is not necessary. Leave it set to "Not activated" unless you are charged penalties for exceeding your power limit.

4. Grid Injection Settings: For Electricity Sellers

This menu is intended for those who have a surplus resale contract (such as EDF OA or Belgian prosumer contracts).

"I have a licence..." checkbox: Enable if you have an official contract

Authorised Injection Time Slots: Set the specific hours during which sales are authorised

Threshold (Very Important!): Tell the AI: "Do not inject if the sale price is less than X €/kWh". Example: 0.08 €/kWh

Maximum Injection Power: Limit imposed by the network operator (e.g. 5 kW)

💰 Our advice: If you sell, activate the control and set a minimum threshold. This prevents you from selling your precious solar energy for a few pence.

5. AC coupling: A special case

This parameter concerns specific configurations with several inverters (AC grid coupling, AC load coupling, AC generator coupling).

🎯 Our advice: If you have a conventional installation with a single Deye hybrid inverter, do not activate this option. Leave it disabled by default.

Step 5: Track Performance and Enjoy the Savings

The configuration is complete, and the AI is working around the clock. But how do you know if it's really effective? The Deye Copilot dashboard shows you exactly what's happening and how much you're saving.

📊 Understanding the Smart Dashboard

Open the Deye Cloud application and select your installation. You will be taken to the main dashboard.

1. Real-Time Price Gauges

Import Gauge (left): Current price at which you are purchasing electricity, with the day's minimum/maximum prices

Feed-in Gauge (right): Price at which you sell your surplus

These gauges allow you to see at a glance whether electricity is expensive or cheap at the moment.

2. Main Graph: Spy on the AI's Decisions

The graph superimposes several curves that tell the story of your energy day:

• Price curve (purple/blue): The solid part = past, the dotted part = forecast used by the AI
• Production curve (green): Energy produced by your solar panels
• Battery curve (orange/yellow): Rises when charging, falls when discharging
• State of charge SOC (%): How full your battery is

🔍 How to interpret Copilot EMS actions

By looking at these curves, you can "spy" on the AI's intelligent decisions:

🎯 That's the magic of Copilot EMS: it doesn't just react, it anticipates!

💰 Track Your Earnings in Real Time

At the bottom of the graph, you will find the key indicators:

• Import €/kWh: How much you bought today (average price)
• Injection €/kWh: How much you sold today (average price)
• Today's revenue: Total earnings = energy not purchased + energy sold
• Production kW / Load kW: Real-time energy flows

You can navigate between "Live", "Day", "Month" and "Year" to get an overview of the profitability of your installation since Copilot EMS took control.

📈 Real testimonial: "Before Deye Copilot, I was paying £150/month for electricity. Since activating it, I'm down to £45/month. The investment in batteries is paid off in 4 years instead of 8!" – 10kW installation + 15kWh batteries
