Detailed Description:

Morningstar PS-30M 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

Morningstar PS-30M 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

Morningstar PS-30M Installation & Operation
The new 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 pushbutton 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 microcontroller with better resolution
 - Extensive digital filtering for improved accuracy
 - Added 2 precision shunts for very accurate current measurement
 - Calibration of the microcontroller during final QA testing in production


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
