About product

Magnum Energy PT-100 Charge Controller The PT-100 is an MPPT (Maximum Power Point Tracker) charge control with a maximum 100 A output. It can charge 12, 24, and 48 VDC battery banks with typical 99% efficiency. It comes standard with both arc-fault detection and ground-fault protection (GFP) which eliminates the need for a separate GFP breaker assembly. The array open-circuit voltage can be as high as 200 VDCbattery voltage or 240 VDC, whichever is lower. The array operating voltage is up to 187 VDC, and battery-charging voltage range is 10 to 66 VDC. An auxiliary dry-contact relay is available for control of generator start or load shedding or similar functions.

The wiring box can be separated from the control for convenient installation and ease of service. There is extensive electronic protection for PV short circuit, high voltage, over-current, and power derating with over-temperature. A digital screen and LED indicators provide system information. There is internal data logging with harvest information data up to 255 days. Use the Magnum Energy system remote display to read this information. Firmware is user upgradeable using downloaded files. Use 300 VDC breakers (see Electrical Distribution Parts) for power source voltages over 150 VDC. On the battery side of the controller, breakers need only be rated for the highest battery-charging voltage, and has a 5-year warranty. Made in U.S.A. ETL Listed to UL 1741 for the U.S.A. and Canada and CSA C22.2 No. 107.1, CE.
