    Detailed Description


    • Short-circuit — solar and load
    • Overload — solar and load
    • Reverse polarity
    • Reverse current at night
    • High voltage disconnect
    • High temperature disconnect
    • Lightning and transient surge protection
    • Loads protected from voltage spikes
    • Automatic recovery with all protections


    • Night Disconnect: The solar array automatically disconnects at night to prevent reverse current leakage from the battery.
    • Battery Sense: Good battery performance requires accurate charging. Voltage drops in the battery power cables can distort the battery charging. The Sense wires eliminate the voltage drops for optimized charging.
    • Temperature Compensation: Four control setpoints (25°C reference) are compensated for temperature (PWM regulation, float, equalization, high voltage disconnect). The charging is compensated by –5 mV/°C /cell (–30mV/°C for a 12V battery). Compensation is limited to minus 30°C.
    • Remote Temperature Probe: An optional probe is available to measure temperature at a location away from the controller. This requires soldering 2 wires to the ProStar PCB.
    • Versions available: 15 or 30 amp 12 / 24 or 48 volt negative or positive ground
    • Estimated 15 year life
    • PWM series battery charging (not shunt)
    • 3-position battery select: gel, sealed or flooded
    • Very accurate control and measurement
    • Jumper to eliminate telecom noise
    • Parallel for up to 300 amps
    • Temperature compensation
    • Tropicalization: conformal coating, stainless steel fasteners & anodized aluminum heat sink
    • No switching or measurement in the grounded leg
    • 100% solid state
    • Very low voltage drops
    • Current compensated low voltage disconnect (LVD)
    • LEDs indicate system status and various faults
    • Capable of 25% overloads
    • Remote battery voltage sense terminals
