Color: 48v Overview This wind turbine controller automates battery charging and protects both turbine and battery through automatic braking and recovery. Housed in a corrosion resistant aluminum alloy case with full seal waterproofing, it is built for outdoor use and harsh environments. Key benefits Automatic charge control and braking: charges the battery until full, then the internal circuit applies braking to stop overcharging. When battery voltage falls to the restore level, charging resumes automatically to maintain system balance. Reverse connection protection: builtin reverse polarity protection prevents damage if battery connections are reversed. No fuse replacement is required; correct the battery polarity to restore normal operation. Durable construction: aluminum alloy body resists corrosion for longer life in marine or coastal settings. Weatherproof sealing: full seal design with protection level IP67 for reliable operation in humidity and saline environments. Main functions and compatibility Function: automatic charge control, automatic braking when battery is full, automatic recovery when voltage drops, reverse polarity protection. Voltage compatibility: DC 12 V to 48 V. Applicable power range: 2000 W to 5000 W. Material: aluminum alloy. Protection level: IP67. Practical applications Offgrid homes: integrate with a small wind turbine system to charge battery banks and prevent overcharge during variable wind conditions. Remote power stations: maintain battery health and reduce manual intervention at remote monitoring sites or telemetry stations. Marine or coastal installations: corrosion resistant and sealed design for use on small docks or shoreline power systems. Package contents 1 x Wind Turbine Controller Condition 100 percent brand
