Magnum PT-100 100A MPPT Charge Controller

Made in USA

The PT-100 is a Maximum Power Point Tracker (MPPT) charge controller designed to harvest the maximum available energy from the PV array and deliver it to the batteries.  The PT-100’s MPPT algorithm finds the maximum power point of the array and operates at this point while regulating the output current and battery voltage to fully charge the battery.


  • Maximum Power Point Tracking (MPPT) technology for increased PV power output efficiency
  • Multi-state Charging for maximizes system performance and improves battery life
  • Optimal Battery Charging using an included external temperature sensor for optimum battery charging, even during extreme temperature changes
  • Compatible with 12, 24, or 48V battery systems with automatic detection of system voltage
  • GFDI: Integrated PV Ground-Fault Detection and Interruption/Indication, with pre-fault leakage/diagnostic metering
  • AFCI: An integrated PV Arc-Fault Circuit Interrupter detects, indicates, and extinguishes series arcs. The AFCI is designed to meet the new National Electric Code (NEC) Article 690.11 requirements
  • Extensive Electronic Protection: Over-temperature protection, power derating when temperature is high, PV short circuit and high PV input shutdown, output overcurrent protection and night-time back-feed (reverse current) protection
  • Supports large PV arrays - a single controller supports a large PV array up to 6600W
  • High Efficiency - provides higher than 99% conversion efficiency and uses less than two watts of power in nighttime mode
  • Multiple LED indicators and large digital LED screen on front panel for easy-to-read system information
  • Convenient Installation - Run all of the wiring to the unique, remain-in-place wiring box with ease prior to installing the full PT-100 unit
  • On-site Updates - The PT-100’s software can be updated on site
  • Easy MP and MMP integration - The PT-100 is designed to work with a Magnum Panel (MP) or Mini-Magnum Panel (MMP). It provides room and access to PV and battery disconnect breakers
  • Optional ME-ARC50 Remote works with internal data-logging functionality that keeps energy harvest information and battery Ah/Wh data for up to 255 days. It is the only remote, currently, that works with the PT-100 menus.
