Talking about the selection of solar street lamp battery
News details
The accumulator stores the electric energy generated by the solar panel when there is light, and then releases it when lighting is needed at night. Some manufacturers have developed solar street light systems that do not use batteries; solar battery packs are connected in parallel with the power grid. Switched by the control circuit. Low investment, low operation and maintenance costs, low energy consumption and stable system operation. Suitable for street lights near the city network. Garden lights. Advertising light boxes, etc. Focus on the solar street light system with battery.
1. Capacity selection
The battery capacity is too small to meet the needs of night lighting; if the capacity is too large, the battery is always in a state of power deficit, which affects the battery life and also causes waste. The ratio of battery capacity (Ah) to load capacity (Ah) should be more than 3 to 6 times: in areas with less continuous rainy days, about 3 to 4 times, and in areas with more continuous rainy days, about 5 to 6 times.
2. Battery connection
When connected in parallel. It is necessary to consider the impact of the imbalance between the individual cells. The number of parallel groups should not exceed 4 groups. Pay attention to the theft of the battery.
