To further our commitment to renewable energy and showcase best-practice installation standards, our in-house team designed, supplied and commissioned a 21.8kW, 3-phase solar PV system at our own premises. This project demonstrates the same engineering quality and attention to detail we deliver for clients—implemented on our site to cut bills, reduce carbon emissions and provide a live demonstration environment for visitors.
The system features 40 × 545W JA Solar panels paired with a FoxESS H3-PRO-20.0 20kW 3-phase inverter for high efficiency and robust performance. A FoxESS Cube 12.44kWh battery provides backup and load shifting, increasing self-consumption during peak times. The array is secured with a Renusol roof mounting kit, with full AC isolation and generation metering to ensure safe operation and transparent monitoring.
