SYSTEM COMPATIBILITY: Designed for use in mid-sized systems. Max battery current: up to 40A (depending on model; see model comparison chart). Max. PV open circuit voltage (Voc) 120V (without damage to unit)
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)
TRAKSTAR MPPT TECHNOLOGY MAXIMIZES ENERGY HARVEST AND LOWERS OVERALL SYSTEM COST: 98% Peak Efficiency. Excellent performance at sunrise and low or variable solar insulation levels. Decreases the number of solar modules needed based on the extra energy harvest
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. Design eliminates cooling fans which can fail, suck in dirt, shorten component life, waste precious solar electricity. Industrial-strength build quality inside and out, right to the controller’s high-impact, rugged durable polycarbonate exterior case.
