SYSTEM COMPATIBILITY: Designed for use in mid-sized systems. Max solar/load current: up to 30A (depending on model; see model comparison chart). Low voltage disconnect included. Constant voltage PWM regulation; 4-stage charging
UNIQUE FEATURES: Load and automatic PV-based lighting control. Charges all battery types including Lithium Ion; has Lithium “fold back” circuitry for safe charging under low temperature conditions. Ideal for use in cloud-connected, networked systems through communications protocols—“speaks” Modbus, and SNMP (with optional EMC-1)
OVER 20 YEARS OF RELIABILITY : Proven in over two decades of use—and continuously improving with the latest Generation III version. “Own both the latest and the legend in a single controller”
EXTENSIVE PROTECTION AND DIAGNOSTICS BUILT-IN: Built-in extensive electronic protection against surge, short-circuit, over-current, reverse polarity conditions. Advanced self-diagnostics warns against installation or user errors. Custom programmability, with or without a PC. Data logging- up to 256 days worth
LOWEST HARDWARE FAILURE RATE IN THE INDUSTRY, BACKED BY A FIVE-YEAR WARRANTY: Most Morningstar products ever built are still in use, some for over 25 years, thanks to smarter digital design, superior internal engineering, and over-spec components. Advanced thermal engineering eliminates cooling fans which can fail, suck in dirt, shorten component life and waste precious energy. The high-impact, durable polycarbonate exterior case illustrates industrial-strength build quality.
