1.0 GENERAL INFORMATION
Thank you for selecting the ProStar solar controller. This second generation ProStar adds new
features and protections using highly advanced technology. Morningstar’s patented PWM battery
charging algorithm has also been further optimized for longer battery life and improved system
performance.
Many functions of the ProStar are unique. Although the ProStar is very simple to use, please take
the time to read this operator’s manual and become familiar with the controller. This will help you
to make full use of the many advantages the ProStar can provide for your solar system.
2.0 IMPORTANT SAFETY INFORMATION
”Always Put Safety First“
• Be very careful when working with batteries. Wear eye protection. Have fresh water
available to wash and clean any contact with battery acid.
• Charge only lead-acid batteries that are properly sized for the system.
• Explosive battery gasses can be present during charging. Be certain there is enough
ventilation to release the gasses.
• Use insulated tools and avoid metal objects near the batteries.
• Carefully read the battery manuals and other equipment manuals before installing
the solar system. Observe ALL precautions when working with batteries and power
electronics.
• Fuses or DC disconnects may be required in the system. These protective devices
are not part of the ProStar controller.
• Avoid large voltage drops in the battery wires. Use the Battery Sense connection for
best battery charging and system performance.
• Do not allow water to enter the controller.
• Avoid touching the controller heat sink. Under certain operating conditions, the heat
sink can become hot.
• Install the controller in a vertical position with adequate space for ventilation.
• Ensure that the system is properly grounded.
• SAVE these instructions for future reference.
3.0 QUICK START INSTRUCTIONS
This section provides a brief overview of how to get started using the ProStar controller. However,
please review the entire manual to ensure best performance and years of trouble-free service.
1. Mount the ProStar to a vertical surface. Allow space above and below the controller
for air flow. The heat sink MUST be in a vertical (up & down) position.
2. Make sure the Solar and Load currents will not exceed the ratings of the ProStar
version being installed.
