In the age of renewable energy, 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.
The New Era: The Rise of Dynamic Tariffs – Why Your Electricity Bill Is Now a Trading Game
The landscape of European electricity is evolving. Where once consumers paid a fixed rate, dynamic time-of-use (ToU) tariffs are now emerging. Widespread rollout of smart meters (80% EU deployment target) now provide detailed consumption data to support that tariff structure.
Simply switching to a dynamic tariff can provide small savings already, as it typically offers slightly lower prices due to the reduced hedging risk for retailers. However, this comes at a risk. Like stock market, prices rise and fall every hour. 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 (3-5x or even more). However, for homes with PV, batteries, and EVs, this volatility unlocks profit instead: store cheap energy, avoid peaks, and sell surplus. 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, constantly buying low, selling high, storing and using energy at the perfect moments. By simply shifting consumption patterns, users can cut bills by 20% (€200–€300 for a typical European household). With grid participation, users can earn additional €100+ from demand response, balancing, and frequency response.
Solis HEMS solution makes this possible by combining cloud-based AI with seamless inverter local control—without the need for additional local gateways. At the heart of this is a robust cloud optimization engine: Solis AI. It automatically calculates the optimal schedule by taking into account:
lElectricity tariff: Solis HEMS supports configuration of various forms of ToU tariffs, with dynamic prices fetched automatically.
lConsumption pattern: Solis AI learns from past patterns of electricity consumption and predicts future load.
lWeather forecast: Solis AI forecasts solar irradiance and hence PV output.
lUser preference: Solis AI allows users to define their own objectives.
With these, Solis AI supports diverse EMS scenarios, ranging from price arbitrage, maximum self-consumption, to negative tariffs, peak shaving, and more. In addition, advanced users can fine tune the behavior further using rich manual settings. This tells the system various boundary conditions and other needs such as energy backup.
If you would like to participate in the imbalance or ancillary markets, Solis HEMS grants you that option by supporting remote dispatch and integration with various VPP platforms. Control can even happen through the cloud without any physical gateway onsite in many countries. Furthermore, Solis joined forces with Enode in a collaboration to create an open ecosystem. Through Enode, Solis HEMS can talk to non-Solis chargers or heat pumps, hence enabling intelligent orchestration of the whole house. 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. All you need is just one SolisCloud APP, in which you can monitor the energy flow, manage device settings, enable the HEMS feature whenever you need and observe the profits. No contracting, no switching of dealers, and no additional installation work.
