"Redstone" is a waterwheel-type small hydropower generator that is installed in rivers and waterways to generate electricity by turning turbines. It can also be used in water circulation systems within factories or at construction sites without power (where water is springing up). Micro hydropower ranges from 0.5 to 5 kilowatts. Its advantages include minimal environmental impact due to its ability to be installed without significantly altering the terrain and its low water usage. It can be utilized by factory personnel, general contractors, subcontractors, civil engineering contractors, and government agencies. 【Features】 ■ Low cost ■ Completely waterproof design using water-resistant materials ■ High efficiency due to direct connection to the waterwheel ■ Grid connection and power selling possible (optional installation required) ■ Battery storage system available (for Redstone Mini) *For more details, please refer to the PDF document or feel free to contact us.
