Step up to Mean Power Point Tracking (MPPT), the most advanced program for harvesting solar energy and charging a battery bank.

Key Features and Benefits:

- High Reliability – conformally coated circuit board and corrosion resistant terminals.
- Maximizes Energy Harvest – using TrakStar MPPT Technology to determine and adjust to the true maximum power point as solar isolation changes throughout the day.
- High Efficiency – at low, medium, and high power levels.
- Data Logging – up to 256 days of detailed power and load data.
- Low Noise Design – meets US Federal Communications Commission Class B specifications.
- Automatic PV Based Lighting Control – field adjustable, multi-event load control enables powerful options for PV lighting systems.
- MODBUS Communications – Solar Industry Standard MODBUS communications protocol allows for easy programming, control, remote data access and charge synchronization.
- High Strength – polycarbonate case and extruded aluminum heatsink.
- Self Diagnostics – continuous monitoring and reporting of any errors through its status LED’s, optional display or communication port.
- Meter (if equipped) – allows adjustments to charging, lighting, and load control settings without a computer.
- Charges all battery types including Lithium Ion
- Continuous charging and no damage from PV array oversizing

Can be used on 12- or 24-volt systems with sealed, gel and wet-cell lead-acid batteries. Front panel LEDs indicate when the batteries are being charged and relative battery state of charge. Reverse polarity protection on input and output. In the event of a load short circuit, the load is automatically disconnected. “M” models include LCD meter of battery voltage, PV charging current, and load current. Low voltage LVD is current-compensated to prevent false disconnect when the battery is heavily loaded. Units are conformal coated to guard against corrosion.
