Introduction
1.0 Introduction
Congratulations on your purchase of the PT-100 Charge Controller. The PT-100 is a Maximum Power
Point Tracker (MPPT) charge controller specifi cally designed to harvest the maximum available
energy from the PV array and deliver it to the batteries. The MPPT algorithm in the PT-100 is
designed to fi nd the maximum power point of the array and to operate at this point while regulating
the output current and battery voltage to fully charge the battery. The PT-100 is simple to use and
reliable, providing maximum fl exibility in sizing your PV array and charging different battery types.
1.1 Key Features and Benefi ts
The PT-100 charge controller includes the following key features and benefi ts:
• Maximum Power Point Tracking technology for increased PV power output effi ciency.
• Continuous charging current up to 100ADC (for 12, 24 or 48V battery systems) and high
input voltage up to 240VDC (Voc).
• PV Ground Fault Detection and Interruption/Indication (GFDI), with pre-fault leakage/
diagnostic metering.
• PV Arc Fault Circuit Interrupter (AFCI) that detects, indicates, and extinguishes series
arcs. Meets the new National Electric Code (NEC) Article 690.11 requirements.
• Multi-stage charging algorithms (automatic bulk, absorption and fl oat, with manual
equalization) to maximize system performance and improve battery life. Suitable for
various types of batteries including fl ooded, AGM, and GEL batteries.
• Automatic battery temperature compensation using an external temperature sensor
(included) for optimum battery charging, even during extreme temperature changes.
• 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 backfeed (reverse current) protection.
• Peak conversion effi ciency is higher than 99% (PV In to DC Out).
• Low self-consumption (<4W) - in night-time mode.
• Built-in programmable auxiliary relay for device control (requires remote).
• Internal data logging functionality keeps energy harvest information and battery Ahr/Whr
data up to 255 days (requires ME-ARC or ME-ARTR remote to display).
• Multiple LED indicators and large digital LED screen on front panel provides charger and
fault status information and important system information (PV power input, PV voltage
input, battery voltage and battery current).
• Easy setup with “link” feature to prevent incompatibility issues between the controller
settings and the inverter charge settings—when networked with a Magnum inverter.
• Remain-in-place wiring box design to prevent the removing of conduit/wiring if service
required. Can also be used to pre-install conduit and wires before electronic section install.
• Ability to update software onsite.
• Designed to work with a Magnum Panel (MP) or Mini-Magnum Panel (MMP) - provides
room and access to PV and battery disconnect breakers.
1.2 Regulatory Compliance
The PT-100 has been tested and listed to UL 1741, 2nd Edition (Standard for Charge Controllers,
Converters and Controllers for use in Independent Power Systems) for use in the US; and is
also certifi ed to CSA C22.2 No. 107.1-01 (General Use Power Supplies) for use in Canada. It
has been tested and certifi ed to these product safety standards by Intertek Testing Services
(known as ETL), which is a Nationally Recognized Testing Laboratory (NRTL). NRTL’s are qualified
organizations that meet Occupational Safety and Health Administration (OSHA) regulations to
perform independent safety testing and product certifi cation.
