Project Summary

To reduce reliance on diesel during South Africa’s ongoing load shedding, Quantum Foods commissioned a hybrid backup power system combining solar energy with a diesel generator for seamless switchover and operational continuity.

This integrated solution is designed to:

• Prioritise solar usage during the day
• Automatically switch to generator only when solar or grid is unavailable
• Use solar PV to reduce the runtime and fuel consumption of the generator during extended outages

Key Features of the System

🔋 Generator & Changeover Infrastructure

• Industrial diesel generator installed in a purpose-built power room
• Custom changeover panel with clear labeling for PV, Generator, and Load sides
• Safety interlocks and surge protection integrated

☀️ Solar PV Monitoring & Control

• Fronius smart inverter system
• Monitors power flow from:
  • Grid
  • Generator
  • Solar
  • Battery (future-ready)
• Ensures 100% solar self-consumption when available
