Fanless design for long-term reliability–no moving parts to fail, no dirt and debris sucked into the controller, and no parasitic load to reduce efficiency.Meter – allows adjustments to charging, lighting, and load control settings without a computer.Low Noise Design – meets US Federal Communications Commission Class B specifications.Self Diagnostics – continuous monitoring and reporting of any errors through its status LED’s, optional display or communication port.Data Logging – up to 256 days of detailed power and load data.High Strength – polycarbonate case and extruded aluminum heatsink. High Efficiency – at low, medium, and high output power levels to maximize energy harvest and minimize heat buildup inside the controller.SNMP Monitoring – when used with the EMC-1 accessory to enable your network management systems to display key solar power metrics and alert/fault codes.MODBUS Communications – Solar Industry Standard MODBUS communications protocol allows for easy programming, control, remote data access and charge synchronization.Maximizes Energy Harvest – using TrakStar MPPT Technology to determine and adjust to the true maximum power point as solar insolation changes throughout the day.Automatic PV Based Lighting Control – field adjustable, multi-event load control enables powerful options for PV lighting systems.High Reliability – conformally coated circuit board, corrosion resistant terminals, premium high-frequency CoilCraft inductors, over-spec’d components, transient surge suppression, and lowest published failure rate in the industry.Manufactured in a Certified ISO 9001 Facility DC coupled solar charge controllers been around for decades and are used in most small scale off-grid. Its job is to regulate the solar output to ensure the battery is charged correctly and not overcharged. The Classic 250 has a maximum output current of 63 amps, an operating voltage of 250 volts and works with 12 to 72 volt battery systems. A solar charge controller, also known as a solar regulator, is a battery charge regulator connected between the solar array and battery. The options are vast when it comes to solar charge controllers including PWM or MPPT ranges and various voltages and amp ratings. Operating Power* – 24 volt batteryĪpproved for use in Hazardous Locations: Class 1, Division 2, Groups A-DĮTL Listed The Classic 250 MPPT Charge Controller has Arc Fault, Ground Fault, free web monitoring, a graphics panel and Solar, Hydro and Wind Modes. Operating Power* – 12 volt batteryģ50W max. Controller will limit and provide its rated continuous maximum output current into batteries. *Input power can exceed Nominal Operating Power.
