Compact MPPT Wind Turbine Charge Controller for 12V, 24V and 48V Systems This sealed, waterproof wind turbine charge controller is designed to manage battery charging automatically, protect the turbine and battery, and improve energy conversion in humid or saline environments. Key features and benefits Automatic system matching: Autodetects and matches 12V, 24V or 48V battery systems for straightforward installation and operation. Wide starting voltage support: Starts turbines at 8V for 12V systems, 17V for 24V systems, and 35V for 48V systems. Automatic braking and recovery: Internal circuitry applies an automatic brake when the battery reaches full charge and restores charging automatically when battery voltage falls to the recovery threshold. MPPT electrodeless noiseless unloading: Uses MPPT control with electrodeless and noiseless unloading to maintain effective charging while limiting voltage and current during recharge. Voltage and current limiting: Builtin limits during charging help protect both the turbine and the battery and optimize charge quality. Reverse connection protection: If battery polarity is connected incorrectly, the controller protects the system so no fuse replacement is required; simply correct the connection and resume operation. Robust environmental protection: Fully sealed, completely waterproof design suitable for humidity and saline conditions such as ground water exposure. Two power ratings available: Controller rate power options of 600W or 800W to suit different turbine and battery setups. Technical specifications Color: 800W Size: Auto 12V24V Controller rated power: 600W or 800W Starting voltage: 8V (12V system), 17V (24V system), 35V (48V system) Battery voltage: Automatch 12V or 24V battery (L or lead acid battery) or 48V Wind braking voltage: 14.5V (12V system), 29V (24V system), 60V (48V system) Wind recovery voltage: 12.5V (12V system), 27V (24V system), 54V (48V system) Controller size: 10.4 x 9 x 2.3 cm Parcel weight: about 350 g Practical applications Offgrid power for cabins and remote homes: Manage wind turbine charging into battery banks for lighting and appliances while protecting batteries from overcharge. Marine and coastal installations: Fully sealed design resists humidity and salinity for small wind turbines on boats, buoys, or coastal sites. Remote pumping and infrastructure: Reliable automatic charging and protection for windpowered pumps, telecom repeaters, or monitoring stations where maintenance access is limited. What this controller delivers Simplified setup for 12V, 24V and 48V systems, automatic protection and recovery, and MPPTbased charging performance in a compact, sealed package suitable for demanding outdoor environments.
