Case Study: High-Performance 24kW / 30kWh Residential Microgrid in France
Elevating French Energy Standards: The Suness & Victron Integration
France is at the heart of Europe’s energy revolution. As electricity prices stabilize but grid-flexibility requirements increase, French homeowners are seeking more than just solar—they want "Uninterrupted Autonomy."
In collaboration with a premier local installer, Suness Power has delivered a high-capacity, Victron-powered residential storage hub. This system is specifically designed to meet the VDE-AR-N 4105 standards and the aesthetic expectations of the French market, all while being fully CE certified.
The System Architecture: Professional Grade
This installation represents a "Heavy-Duty" residential solution, ideal for luxury villas or rural estates in regions like Provence or the Alps, where grid resilience is a priority.

| Solar Configuration | Compatible with High-Voltage & Low-Voltage DC Coupling |
| Target User | Local Professional Installers (EPC) |
| Compliance | Full CE Certification & French Grid Code Ready |
Strategic Project Highlights
The Victron Advantage: World-Class Inversion
By integrating three Victron 8kW units in a balanced three-phase configuration, we provide 24kW of continuous power. For the French market, where Victron is highly respected for its open-source communication and "blue-chip" reliability, this setup allows for complex load management, including swimming pool heat pumps and high-speed EV chargers (Bornes de Recharge).
30kWh Suness LFP: The "Storage Core"
Our 51.2V 200Ah wall-mounted batteries were selected for their high discharge capability and sleek vertical footprint. In France, where utility space is often limited, our compact 10kWh units allow for a parallel stack of 30kWh without occupying significant garage or basement floor space.
Scalability for Local Installers
This project serves as a blueprint for French installers. The system is modular; installers can start with one 10kWh unit and expand to three or more as the homeowner's needs grow. This "pay-as-you-grow" model is a key selling point for the modern French residential sector.
French Market Context: The "Zéro TVA" & Grid Outlook
Incentives: The 0% VAT (TVA à 0%) policy on solar and storage in France continues to make these high-capacity systems financially attractive for homeowners.
Peak/Off-Peak Optimization: With the French grid moving toward more dynamic pricing, our intelligent BMS (Battery Management System) allows for "Arbitrage"—charging from the grid when prices are low and discharging during the expensive evening peaks (Heures Pleines).
Grid Resilience: In rural France, storm-related outages are a reality. This system provides a Seamless UPS (Uninterruptible Power Supply), ensuring that the French "art de vivre" is never interrupted.
