    Detailed Description

    Electronic

    • 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

    Charging

    • 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.
