High-performance MPPT charge controller with fast, precise tracking and smart battery management Key benefits Rapid MPPT lock: Proprietary algorithm finds and locks the maximum power point within 10 seconds, so your panels start delivering optimal power quickly. High accuracy and efficiency: MPPT tracking accuracy greater than 99% and peak conversion efficiency up to 98% maximize energy harvest and reduce losses. Better battery life and charge control: Four-stage charging manages current and voltage to speed charging when appropriate and protect batteries over the long term. Smart temperature compensation: External temperature sensor enables accurate temperature compensation to prevent over- or under-charging in different environments. Broad compatibility: Automatically detects and supports 12V or 24V system voltages for easy integration with common solar battery banks. What it does (functions) Fast MPPT tracking: Uses a self-developed algorithm to quickly find the true MPPT and maintain stable operation, improving energy capture from PV arrays under changing sunlight. Four-stage charging: Implements high-current charging at MPPT points, followed by trickle charging, absorption charging, and balanced charging to ensure batteries are charged efficiently and kept in good condition. Automatic system voltage selection: Detects 12V or 24V systems automatically—no manual switching required. External temperature sensing: Measures battery temperature and applies temperature compensation to charging parameters for safer, more accurate charging. Performance highlights MPPT lock time: within 10 seconds Tracking accuracy: >99% Peak MPPT conversion efficiency: 98% Charging stages: high-current (MPPT point), trickle, absorption, balanced System voltages: 12V / 24V automatic detection Temperature compensation: via external sensor Practical applications Off-grid homes and cabins: Quickly harvest available solar power and manage battery charging to extend battery life and reliability in remote installations. Mobile systems (RVs, boats): Automatic 12V/24V detection and fast MPPT locking improve energy availability in variable sunlight while protecting the battery bank. Small commercial or backup power systems: Consistent high-efficiency MPPT tracking and staged charging maintain performance and battery health in backup or small-scale commercial installations.
