Case: Street Lighting Project in a Hebei Town
A town in northern Hebei Province, with cold winters and hot summers, installed Liwei lithium battery street light heads (12.8V 80Ah) paired with 100W LED lamps and 120W solar panels. Over two years of operation, the system generates about 500Wh daily, storing solar energy during the day for night-time illumination, saving approximately ¥800 annually in electricity costs. The system provides normal lighting even during continuous cloudy/rainy days (up to 5 days), effectively solving the town's road lighting issues.
Q1: What are the installation requirements for the lithium battery street light head?
A: Requirements include: 1) Solar panels facing south without shading; 2) Ambient temperature between -20°C and 60°C; 3) A solar charge controller compatible with the lithium battery; 4) A well-ventilated installation location away from direct sunlight.
Q2: What does daily maintenance involve?
A: Routine maintenance includes: 1) Regular visual inspection for bulging or deformation; 2) Keeping solar panels clean, removing dust monthly; 3) Avoiding deep discharge; recommended SOC between 20%-80%; 4) For long-term storage, charge to 50%-60% SOC and recharge every 3 months.
Q3: What is the warranty policy?
A: Tianjin Liwei offers a 3-year warranty. Free replacement is provided if capacity degrades beyond 20% within the warranty period. A 48-hour on-site repair service is available. The company also offers recycling services for old batteries.
