Solar Street Light Energy Storage Optimization
Client: GreenWay Renewable Energy
Industry: Urban Infrastructure

Challenge:

• Existing lead-acid batteries failed in -30°C Nordic winters
• Required 10-year maintenance-free operation with <20% capacity衰减
• Daily 15hr illumination demand with 3-day backup

Solution:
✓ Lithium iron phosphate (LiFePO4) batteries (12.8V 100Ah)
✓ Carbon-zinc battery arrays for emergency load switching
✓ AI-powered charge controller with self-heating function

Results:

• Operated at -40°C with 98% depth of discharge
• Reduced tower maintenance visits from 6x/year to zero

• Scaled to 12,000 units across Scandinavian cities

•
