Constant Flow Solar Fountain with Battery Backup - Our 2.5W solar panel and 800mAh battery provide reliable performance, allowing the fountain to store excess energy when exposed to sunlight. This stored power helps maintain consistent water flow, enabling the fountain to operate smoothly even under low-light conditions. Solar Panel Circuit Enhancement - The fountain continues to function with steady flow even if part of the solar panel is partially shaded, offering improved performance over standard solar fountains that may stop under similar conditions. High-Quality Laminated Solar Panel - Constructed with durable solar laminates, the panel resists cracking, warping, and peeling, ensuring long-term outdoor use compared to lower-quality epoxy-based panels. Idle and Jam Protection - The pump automatically shuts off if it detects operation out of water or blockage from debris, helping prevent overheating and extending the pump's lifespan. For optimal performance, ensure adequate water levels and clean the pump regularly if flow decreases. Note: Measurements are manually taken; please allow a 1-9 cm variation. Color may vary slightly due to lighting and screen settings. Actual product appearance may differ slightly from images.
