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.

Options

  • Digital meter

    A precision 3-digit digital meter will continuously display battery voltage, solar current, and the load current. The meter automatically scrolls through these 3 displays. The 3 red LEDs will indicate which parameter is being displayed.

    The digital meter will operate from –30°C to +85°C. The values displayed are calibrated electronically in production and are accurate to within a few percent. Please note, however, that if the Battery Sense is not connected, the voltage displayed will be in error by the voltage drops in the battery wires.

    • Highly accurate voltage and current display
    • Low self-consumption (1 mA)
    • Includes manual disconnect button
    • Displays 5 different protection functions and disconnect conditions
    • Self-diagnostics (self-test) provides a comprehensive test of the ProStar —
      • Displays 9 different controller status parameters, including temperature
      • Displays detected faults
  • Positive ground
  • Remote temperature probe

    An optional remote temperature probe can be soldered to the ProStar assembly at any time. The standard cable length is 25 ft (7.6 m), and this can easily be extended to 100 ft (30 m) or longer. The 2 probe wires are soldered to the main board assembly between the temperature sensor and the green LED, at "J12".
