Application
Solar, battery and diesel integration
The context
- Product: ePowerControl MC
South Africa’s largest retail and digital bank has adopted solar to reduce grid reliance, cut energy costs, and operate off-grid during load shedding. The site features 7 Huawei inverters and a 500 kW battery system. Using Elum ePowerControl MC for reliability and cost optimization, the plant operates in two modes:
- Grid Prime mode: The generator is offline, the PV plant limits active power injection at the Point of Common Coupling (PCC), and charges the battery.
- Genset Prime mode: The genset regulates system voltage and frequency, while the BESS operates in grid-following mode, ensuring minimal genset load and reduced diesel reliance.
- Layout:
PV: 700 kWp - BESS: 500 kWh
- Gensets: 2500 kW
- Inverters: 7 x Huawei 100 KTL
BESS: ATESS 500 kWh - Gensets: DeepSea 2500 kW
