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

A traditional energy management system (EMS) simply follows predefined rules. Deye Copilot goes far beyond this thanks to artificial intelligence that continuously analyzes a multitude of data points to make optimal decisions.

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

Deye Copilot's main advantage lies in 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 analyzes electricity price forecasts for the next 24-48 hours and automatically programs:

1. Charging batteries during off-peak hours : when electricity is cheapest (night, weekend)
2. Strategic offloading during peak hours : using stored energy when prices are high
3. Optimized network injection : reselling surplus at the best price points
4. Maximized self-consumption : priority given to using your free solar production

“With Deye Copilot, we 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 based on their maximum power consumption. Deye Copilot natively integrates this advanced function:

• Power peak limitation : the batteries automatically discharge to smooth out power demands during machine start-ups or peak consumption.
• Capacity cost reduction : up to 40% decrease in costs related to contracted power
• Business continuity : securing supply during network constraints
• Network compliance : automatic adherence to power limits imposed by the network operator

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