Why an AI-driven EMS is revolutionising the profitability of solar installations

A traditional energy management system (EMS) simply follows predefined rules. Deye Copilot goes much further thanks toartificial intelligence that continuously analyses a multitude of data to make the best decisions.

Dynamic tariff optimisation: reduce your electricity costs by up to 70%

The main advantage of Deye Copilot is its ability to automatically manage your solar batteries based on dynamic electricity tariffs. The system supports two types of tariff structures:

How does it work in practice? Deye Copilot analyses the forecast electricity prices for the next 24-48 hours and automatically programmes:

1. Battery charging during off-peak hours: when electricity is cheapest (night-time, weekends)
2. Strategic discharge during peak hours: use of stored energy when rates are high
3. Optimised grid injection: resale of surplus at the best tariff times
4. Maximised self-consumption: prioritising the use of your free solar energy

"With Deye Copilot, we have reduced our electricity bill by 62% in 6 months. The system perfectly anticipates price peaks and uses our batteries at the optimal time." — Professional user testimonial

Peak shaving: secure your energy supply

Peak shaving is an essential feature for SMEs and businesses that pay penalties on their maximum power demand. Deye Copilot natively integrates this advanced feature:

• Power peak limitation: batteries automatically discharge to smooth out power demands during machine start-ups or consumption peaks
• Capacity cost reduction: up to 40% reduction in costs related to subscribed power
• Business continuity: secure supply during network constraints
• Network compliance: automatic compliance with power limitations imposed by the network operator

For businesses in Belgium with capacity tariffs (kVA billed at a monthly maximum), peak shaving becomes a major lever for savings. Deye Copilot continuously monitors your consumption and instantly injects the battery energy needed to stay below the defined power threshold.

Deye Copilot for private individuals: autonomy and everyday savings

Residential owners equipped with photovoltaic panels and batteries are discovering a new dimension of energy autonomy with Deye Copilot.

Optimised smart self-consumption

Deye Copilot's artificial intelligence analyses your consumption habits and cross-references them with solar production forecasts to maximise your self-consumption rate:

• Learning routines: identifying periods of high consumption (mornings, evenings, weekends)
• Weather forecasting: PV production forecast over 48-72 hours to adjust the storage strategy
• Solar prioritisation: maximising the use of free, locally produced energy
• Minimisation of grid purchases: drastic reduction in peak-time consumption

Total financial transparency

Deye Copilot offers complete visibility into your economic performance with dedicated dashboards:

• PV resale gains: accurate calculation of grid feed-in revenues (Feed-in Earnings)
• Self-consumption savings: valuation of solar energy consumed vs. grid purchase price (Consumption Savings)

We recommend that you contact Wattuneed to find out the current terms and conditions and receive personalised support for your project.

2. Can my existing Deye installation be equipped with Copilot?

Yes! Deye Copilot is compatible with all existing Deye hybrid inverters, provided they are connected to the Deye Cloud. It is a software activation that does not require any hardware modifications. Your installation simply needs to have an internet connection (WiFi or Ethernet) and have its electricity tariffs configured in the application.

3. Can I use Deye Copilot with batteries from brands other than Deye?

Absolutely! One of the great advantages of Deye Copilot is its universal compatibility with all battery brands that communicate via standard CAN or RS485 protocols. Whether you have batteries from Pylontech, BYD, Delong, APsystems or other manufacturers, Deye Copilot will be able to control them effectively. Only the inverter needs to be from Deye.

4. What is the difference between autonomous mode and manual mode?

In autonomous mode (recommended), Deye Copilot's artificial intelligence automatically makes all battery charging/discharging decisions to maximise your savings. In manual mode, you take back control and set the time slots and management strategies yourself. You can switch between the two modes at any time according to your needs or preferences.

5. Does Deye Copilot work without an internet connection?

No, Deye Copilot requires a permanent internet connection to function. The system must be able to retrieve electricity rates and weather forecasts in real time and communicate with Deye Cloud servers to execute its optimisation algorithms. In the event of a connection loss, the Deye inverter continues to operate according to its last programmed configuration, but intelligent optimisations are suspended.

6. How long does it take for the AI to 'learn' my habits?

Deye Copilot's artificial intelligence starts optimising from day one, but its performance improves gradually. After 2-3 weeks, the system will have identified your main consumption patterns. After 2-3 months, it will have a perfect understanding of your seasonal, weekly and daily variations. Learning continues on an ongoing basis to adapt to any changes in your habits (teleworking, new equipment, etc.).
