The Relay Driver™ is a logic module which provides high level system control functions such as high/low voltage alarms, load control and generator start. The product controls four independent relay driver outputs by reading digital data inputs from Morningstar’s TriStar controller or by reading battery voltage when used in systems with other controllers.
They’re worth it, because they provide the faster power “tracking” that lets us engineer this much power and control into a compact design.
Combined with premium, “over-spec’d” components, this greatly improves control response which guards against system transients, regulation overshoot and overcurrent/overload conditions
Nature do your worst–this controller can take it
If you’ve ever trashed a lesser terminal during an installation, you’ll appreciate some “overkill” here
Allows the surface-mounting of critical components underneath the main board next to the heat sink, which reduces heat travel distance and keeps the controller even cooler
As opposed to cast aluminum, which is less effective in passive cooling applications
“Talks solar” with standard industry language, for system monitoring and cloud connectivity-speaks Modbus, and SNMP (with the EMC-1)
Lithium batteries are expensive and vulnerable to cold temperatures. When it gets close to freezing, the controller backs-off charging to avoid damaging batteries
All-digital calibration for high accuracy, using the same efficient technology found in advanced mobile device
Morningstar’s hallmark MPPT technology precisely seeks and locks onto the true maximum power point quickly and accurately, to ensure the highest output possible from a solar array
When you’ve been in the field installing, you appreciated being able to read a crisp, high contrast display on site
Up to 2 1/2 times longer than some competitors in this class
ProStar is smart enough to monitor and analyze system performance, and alert you when you need to know
Heat is the enemy of all electronics. That’s why Prostar’s critical components are rated to withstand temperatures right up to the boiling point of water (100°C)
Protects the precision electronics inside with an impact strength 30 times greater than the acrylic thermoplastics commonly found on lesser controllers
Just kidding. We’ve never needed them
