HC3 Spot EMS Pro – Buy & Sell
Control of inverter and battery storage. Smart optimization of consumption, battery charging and sale of excess energy, according to spot market price.
⚡📈 HC3 Spot EMS Pro – Intelligent buying and selling of electricity
HC3 Spot EMS Pro is the highest level of energy automation for users who want to transform their photovoltaic power plant into an active tool for generating savings. The package combines the uncompromising performance of the Fibaro HC3 control unit with advanced algorithms of the Spot EMS Pro system for comprehensive optimization of electricity purchasing and selling according to current market prices .
The result is a fully autonomous system that responds intelligently to the market and ensures that your energy always has the highest possible value.
💼 Business presentation
In the era of dynamic tariffs, it is no longer enough to just generate energy – it must be managed intelligently. The Spot EMS Pro package actively plans energy flows in the home: when prices are negative or very low, it buys energy from the grid to charge batteries, while during price peaks it maximizes the sale of surpluses or draws from its own reserves .
This approach dramatically shortens the payback period of PV systems and protects users from unfavorable market conditions. Thanks to the powerful HC3 unit, the system is ready for immediate reaction and future expansion with additional smart home elements.
🧠 Supervisory system and communication
At the heart of the entire solution is the professional control unit Fibaro Home Center 3 (HC3) .
The unit allows stable connection via Wi-Fi and LAN and communicates with the inverter via the Modbus TCP protocol .
The system continuously evaluates market data in combination with insolation forecast (PV forecast) and object consumption predictions, creating an optimal energy plan for each hour of the day.
🧩 Software layer (Package contents)
The package includes complete software equipment for professional energy management:
- QA Spot Pro: Complete spot control. Intelligently plans battery charging, energy usage, activation of selected devices and sale of excess energy based on current hourly electricity prices.
- QA Inverter: Provides comprehensive monitoring of energy flows in real time and serves as a tool for active management of inverter operating modes and battery storage.
- QA EMS: Central logic for dynamic energy balance management that intelligently prioritizes the use of PV surpluses for the facility's own consumption.
- Insolation forecast: QA PV Forecast (without annual fees) – can be extended with a paid version Solcast (Recommended: quality and data availability guarantee).
⚙️ Key features
