ProStar PS-30M PWM Charge Controller (30 amp 12V or 24V w/ display & positve ground)

This sophisticated line of PV charge controllers incorporates constant voltage PWM to make maximum use of valuable PV power. They have automatic equalization, temperature compensation and very high efficiency. They can be used on 12-, 24- and 48-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. Dimensions: 6.01" x 4.14" x 2.2". 5-year warranty.

Detailed Description:

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-30M-PG 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

Digital Meter Display
Completely redesigned, improved and expanded the digital meter.

    * Meter reads values directly from the microcontroller
    * Very accurate voltage and current values measured and displayed
    * Added self-test with specific faults and conditions displayed
    * More status and protection conditions are displayed
    * Reduced self-consumption to 1 mA
    * Current is now measured in the ungrounded leg only
    * Meter connector is more robust and easier to attach
    * Any meter can now be mounted to any ProStar with no calibration required


Morningstar 
PS-30M-PG 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 freqency 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-30M Reliability
Expected failure rate will be less than 1 per 1,000 units over 5 years.

    * Improved 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

Accuracy
Precision design for improved performance and accurate meter display.

    * Added 0.1% resistors and other precision components
    * Upgraded to a more powerful, faster micro controller with better resolution
    * Extensive digital filtering for improved accuracy
    * Added 2 precision shunts for very accurate current measurement
    * Calibration of the micro controller during final QA testing in production
