The ProStar was first marketed to the solar industry in 1995 and has since become the world's leading mid-range controller for both professional and consumer applications. By using highly advanced technology, this second generation ProStar sets new standards for reliability and self-diagnostics. The new ProStar also provides several unique features and protections. And Morningstar's patented PWM battery charging has been further optimized for longer battery life and improved system performance. Standard 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.
Electrical Protection Features: 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. Digital Meter features: Highly accurate voltage and current display, Low self-consumption (1 mA), Includes manual disconnect button, Displays 5 different protection functions and disconnect conditions, Self-diagnostics (self-test) provides a comprehensive test of the ProStar, Displays 9 different controller status parameters, including temperature, Displays detected faults.
