Description
 

MODEL NUMBER: PS-15M
Features
  • Includes Digital Meter
    Rated Solar Current: 15 Amp
    Rated Load Current: 15 Amp
    System Voltage: 12/24 Volt
    Warranty: Five years


    Morningstar's ProStar is the world's leading mid-range solar controller for both professional and consumer applications. This second generation ProStar:

    Adds new features and protections using highly advanced technology
    Provides longer battery life and improved system performance
    Sets new standards for reliability and self-diagnostics


    Morningstar PS-15M Key Features:

    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)
    LED's indicate battery status and faults
    Capable of 25% overloads
    Remote battery voltage sense terminals


    Morningstar PS-15M Electronic Protections:

    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



    Please note that one is not able to control the frequency of battery equalization.
    Furthermore, the Prostar only equalizes up to 15.1 volts and most flooded lead acid batteries list 15.5 volts.


    Morningstar PS-15M Reliability

    Expected failure rate will be less than 1 per 1,000 units over 5 years.


    mproved protections and added many new protections (see list below)
    Power MOSFET voltage rating increased 25%
    Eliminated all trim-pots and other troublesome parts
    Reduced the digital meter components from 75 to 16
    Increased the current-carrying copper traces by 75%
    Increased temperature rating of many parts
    Made conformal coating protection standard


    Battery Charging
    Expanded the battery charging options and capabilities.


    Added a third battery type selection (gel, sealed, flooded)
    Added a "float" stage to the battery charging algorithm
    Expanded the to account for depth of discharge history
    Added a remote temperature probe option
    Improved the accuracy of all charging parameters
    Moved the built-in temperature sensor to read ambient conditions more accurately


    Installation & Operation
    The new Morningstar ProStar is easier and safer to install and use, with more operating information provided to the user.


    Self-diagnostic test provides assurance the controller is working correctly, or indicates a fault that is present

    Rotary switch provides simple and positive selection of battery type (and LED's confirm the selection)

    Terminals are longer with more screw threads, screwdriver holes in the case are larger, and plastic tabs isolate the terminals

    The push button disconnects the load first (for weekend cabins, boats, etc.), then disconnects the solar if held down for 2 seconds (indicated in the meter)

    Five protection functions are displayed in the digital meter

    Meter indicates "OFF" if solar or load is disconnected

    PWM is indicated in the green battery status LED (blinking)

    A telecom jumper eliminates PWM noise if present

    Mounting standoffs prevent stress cracks in the case


    Protections
    Protection against abuse and faults is now comprehensive.



    Added solar short circuit and overload protection / auto recovery

    Added load overload protection / auto recovery

    Improved load short circuit protection / auto recovery

    Improved protection of the load from voltage spikes

    Improved low battery voltage and brownout protection / auto recovery

    Other existing protections have been improved
