MPPT Solar Charge Controller POWM80PRO and POWM100PRO Overview A performance MPPT solar charge controller available in 80 amp and 100 amp versions. Designed for 12 volt, 24 volt, 36 volt, and 48 volt battery systems with automatic voltage recognition. Optimizes solar array output and supports system expansion by paralleling up to 12 units. Key benefits Improved energy harvest through Maximum Power Point Tracking technology, increasing conversion efficiency across varying PV voltages and conditions. Flexible system compatibility with automatic detection for 12 V, 24 V, 36 V, and 48 V battery banks. current handling for larger battery banks and higher charging rates, available in 80 A and 100 A models. Scalable design that allows parallel connection of up to 12 controllers for larger installations or redundancy. Simple integration into charging, lighting, and system voltage control applications. Main features Models: POWM80PRO (MPPT 80 A) and POWM100PRO (MPPT 100 A). Supported battery voltages: 12 V, 24 V, 36 V, 48 V with automatic system recognition. Maximum PV input open circuit voltage Voc: 160 V. Parallel expansion: up to 12 units. Enclosure protection rating: IP32, suitable for indoor or sheltered installations. Typical applications: charger controller, solar systems controller, voltage controller, lighting controller. Performance and compatibility Delivers steady charging current up to 80 A or 100 A depending on model to charge lead acid or lithium battery banks sized for 12 V through 48 V systems. Works with PV arrays where Voc does not exceed 160 V, providing headroom for common module configurations. Parallel capability enables higher total charging current or distributed control across battery banks and load zones. Practical use scenarios Offgrid home or cabin: Manage PV array charging for a 24 V or 48 V battery bank, improving daily energy capture and maintaining battery health. Remote lighting and equipment: Power and control solar lighting circuits while regulating system voltage and charging for reliable nighttime operation. Larger systems or modular expansion: Combine up to 12 controllers in parallel to scale current capacity for community microgrids, agricultural pumps, or distributed storage arrays. Installation notes Install in a dry, ventilated location consistent with IP32 enclosure rating. Ensure PV array Voc remains below 160 V and that wiring and fuses are sized for the controller current rating and system configuration. Use parallel configuration guidance from the controller manual to balance multiple units correctly.
