150kW Deye Hybrid System
Project Overview
- Location: Abraham Kriel Kinderhuis, Potchefstroom, North West
- Application: High-demand institutional backup and grid-tied optimisation for a large residential child care campus housing over 200 children.
- Primary Driver: Eradicating the disruptions of load shedding and escalating utility costs to safeguard the children’s daily needs (cooking, security, lighting, and study spaces).
Technical Profile
- Inverter Architecture: 3 x Deye 50kW Three-Phase Hybrid Inverters running in parallel. Deye’s unique ability to parallel multiple high-capacity hybrid units makes them the industry go-to for commercial applications of this size.
- Solar Array: 300kW of high-efficiency PV modules (550w tier-1 panels) to ensure the 150kW inverters can comfortably run maximum daytime loads while simultaneously fast-charging the battery banks.
- Storage Capacity (Battery Room): High-voltage lithium battery storage Deye BOS-G, ensuring the campus can maintain essential services through extended night-time outages.
Operational Impact & Strategy
- Generator Integration: Deye’s dedicated “Smart Load” or generator input port is crucial here. If prolonged bad weather hits during grid outages, the system can automatically start and manage an existing diesel generator, running it only at peak efficiency to top up the batteries, cutting diesel costs dramatically.
- Essential vs. Non-Essential Management: The dual outputs on these commercial units allow the facility to instantly drop heavy, non-critical loads if the grid fails, keeping the lights, security perimeter, and refrigerators running uninterrupted.
Financial & Sustainability Metrics
- Estimated Monthly Savings: Roughly R45,000 to R65,000+ per month.
- Strategic Value: For a non-profit organisation, shifting predictable monthly overheads from variable utility costs to zero-rated solar power allows long-term operating budgets to be reallocated directly to child care, specialized staff, and educational resources.
