SYSTEM COMPATIBILITY: Designed for use in smaller systems. Max solar/load current: up to 20A (depending on model; see model comparison chart). Low voltage disconnect included (L models). Constant voltage PWM regulation; 4-stage charging

Unique Features: Tropicalized and hardened for field use with epoxy encapsulation, marine rated terminals. Includes wire terminal cover

RATED FOR USE IN HAZARDOUS LOCATIONS: meets UL/CSA requirements for Class 1, Division 2, Groups A-D for oil & gas and other critical environment applications. T5 temperature rating for up to 100⁰C/212⁰ F (boiling water)

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. Factory pre-sets mean no required installation settings

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.
