Smart Energy, Smarter Living: Revolutionizing Home Energy Management

In the age of renewable energy and smart technology, the way we manage power in our homes is undergoing a major transformation. As more people install PV, battery storage, and EV chargers, households are no longer just passive consumers of electricity—they're becoming savvy energy managers, traders, and even mini power plant operators. At the heart of this shift? Dynamic electricity pricing and AI technologies that make it possible to profit from it. (At the upcoming Intersolar 2025, we're) Solis is excited to introduce our game-changing solution to navigate the complexities of the dynamic electricity market. 

The New Era: The Rise of Dynamic Tariffs – Why Your Electricity Bill Is Now a Trading Game

The landscape of European electricity is rapidly evolving. Where once consumers paid a fixed rate regardless of the time of day, dynamic time-of-use (ToU) tariffs are now emerging as the new standard. This trend was driven by the broader shift toward renewable energy, digitalization, and increased consumer engagement. Widespread rollout of smart meters now provide consumers and utilities with detailed, real-time consumption data to support that tariff structure. While countries like Italy, Sweden, and France are leading in smart meter penetration and tariff innovation, others are gradually catching up, aided by EU policies targeting an 80% smart meter deployment rate and more flexible electricity markets. 

Switching to a dynamic tariff without changing consumption patterns can provide small savings for consumers already, as it typically offers slightly lower average prices due to the reduced hedging risk for retailers. However, this comes at a risk. Like stock market, prices rise and fall every hour based on demand, weather, and renewable energy availability. One morning, you might pay €0.10 per kWh to charge your electric car; by the next morning, that same charge could cost €0.50. In general, peaks can easily be 3-5 times higher than valleys, even skyrocketing to crazy levels at extraordinary circumstances. 

However, for homeowners with PV systems, batteries, and EV chargers, this would not be a problem, but instead opens up a range of opportunities. Batteries can stock up electricity when it is cheap and use the stored energy during expensive peak hours. With the added possibility of selling excess energy back to the grid, homeowners can not only lower their bills but even generate a steady income stream. This “smart” approach to energy consumption is the future of sustainable living. 

The Secret to Earning Money – Meet Your Home's New Energy Trader

To ace in the game, you need a good Home Energy Management System (HEMS). Think of it as having a Wall Street trader living in your inverter, constantly buying low, selling high, storing and using energy at the perfect moments. By simply shifting consumption patterns, users can save 20% of their electricity bill (€200–€300 for a typical European household), hence reducing payback time of their solar and storage investments by as much as 2 years. With some grid participation, users can earn additional revenue of about €100 or more from demand response, balancing, and frequency response. With projected twelvefold revenue growth by 2035, HEMS are poised to become a cornerstone of the decentralized, digital energy transition. 

Solis HEMS solution harnesses these trends by combining cloud-based AI with seamless inverter local control—without the need for additional local gateways. At the heart of this innovative system is a robust cloud optimization engine: Solis AI. It automatically calculates the optimal charge/discharge schedule by taking into account all the relevant information, including: 

● Electricity tariff: Solis HEMS supports configuration of various forms of ToU tariffs, including static and dynamic ones. Dynamic prices are fetched automatically by simply specifying the tariff source. These prices reflect the true costs/profits customers pay/get for buying and selling electricity. 

● Consumption pattern: Solis AI learns from past patterns of electricity consumption and predicts future load at the household. 

● Weather forecast: Solis AI forecasts solar irradiance and hence PV output, so it knows how much energy surplus or deficit there is at any future time. 

● User preference: Solis AI allows users to define their own objectives. 

With these capabilities, Solis AI is powerful enough to support very diverse EMS scenarios, ranging from price arbitrage, maximum self-consumption, to negative tariffs, mixed usage, and more. In addition, advanced users will be able to fine tune the HEMS behavior further by manually turning a rich set of knobs. This tells the system various boundary conditions and other user needs such as peak shaving and energy backup. 

If you are not satisfied with user side (behind-the-meter) optimization, but would like to participate in the imbalance or ancillary markets, Solis HEMS grants you that option by supporting remote dispatch. Having long embraced open ecosystem, Solis inverters can be integrated with various VPP platforms. This control can even happen through the cloud without any physical gateway onsite, given authentication. Simply enroll in a VPP program, and grant access to the inverter via SolisCloud. 

Beyond battery scheduling, the system intelligently orchestrates the operation of energy-intensive devices such as EV chargers and heating systems. In a recent move, Solis joined forces with Enode in a collaboration to bring different OEMs together seamlessly to support grid needs. Through Enode, Solis HEMS can talk to non-Solis chargers or heat pumps, hence can do a deeper optimization with just Solis system. Vice versa, Solis inverter opens up itself through Enode to other EMS, enabling homes to connect with innovative energy services and play a more active role in the energy transition. 

An Easy Path Towards the Future – hassle-free onboarding

To manage your household energy today, you often need a tangle of apps for solar, storage, EV chargers, energy retailers, VPP companies, or a dedicated HEMS provider with a gateway to be wired locally. Our solution? Plug in one inverter, and your home becomes self-optimizing. The basic HEMS functions are completely free of charge. All you need is just one SolisCloud APP. In the same APP, you can monitor the energy flow in the household, manage device settings, enable the HEMS feature whenever you need and observe the profits. Having a taste of the energy future is just that hassle-free. No contracting, no switching of dealers, and no additional installation work. 

Your home isn't just a place to live anymore. It's a power plant, a battery, and a savvy energy trader—all rolled into one. Do join the revolution by seeing us at Intersolar 2025. Let's find out how to make every kilowatt-hour count.
