Product information

If you are charging your 12V or 24V battery bank with a medium size solar array up to 1100W, the Prostar MPPT charge controller will provide you with exceptional reliability. It is the ideal product for medium-size solar arrays, controlling and monitoring fundamental aspects of your system. It performs continuous self-diagnostics to detect and report any potential errors, provides helpful information, and monitors battery life. 

Prostar charge controllers utilize an advanced version of Morningstar’s charging algorithm. This is Prostar's third generation of charge controllers, and they have maintained their high quality while adding more features. They are rated for indoor use and operate with 12V and 24V off-grid systems. A wide range of battery types is compatible with these charge controllers, such as sealed, lithium-ion, gel, AGM and flooded lead-acid.

The difference between PMW and MPPT controllers is the algorithm they follow to harvest power from the solar array. While the PMW (Pulse Width Modulation) charge controllers simply pull down the energy from the solar array, the MPPT (Maximum Power Point Tracking) quickly and accurately determines the array's most powerful point, providing 10-15% more charging capability. While this percentage might not be significant for small systems, it can make a considerable difference for medium and large systems.

Main features:
-Front display (optional) shows production values, system temperature, voltage, and current
-Meter display (optional) can program charging points, load control, communications, and advanced settings
-Charging status is indicated by 3 LEDs as well as any other solar input errors, thanks to its battery voltage stage terminals
-Durable equipment with a life expectancy of 15 years
-Saves daily data logging for up to 256 days
-Includes reverse polarity protection on input and output
-Comes with one RJ-11 meter bus port, lighting control, eight settings switches, custom settings, adjustable load control, protective terminal cover, firmware updates, and meter directional buttons
-Compliant with IEC 62109
