EXELTECH PV AC Module mounted to a PV panel. All DC wiring is enclosed in the compartment near the PV frame. The inverter is mounted in the center compartment. AC wiring is pre-installed and may be terminated with provided insulation displacement connectors. What is a PV AC Module? An EXELTECH PV AC module is a self-contained, UL-1741 compliant inverter that produces clean, sine-wave electricity for grid-tie applications without the complexity or expense common in large-string-inverter-based systems. Advantages Over Conventional Grid-Tie Systems 50% reduction in wiring requirements! This eliminates: +DC wiring +DC cable trays +DC fusing, over-current protection and required holders +DC connectors +DC ground-fault detection, protection, and devices +DC surge protection +DC combiner boxes +DC junction boxes and connector blocks +UL-related DC cabling issues +PV Series (“blocking”) diodes +PV module bypass diode Additional Benefits of Exeltech PV AC Modules +No batteries to purchase, maintain, or wear out! +More reliable - single failure does not disable entire system! +Simplified system assembly - AC wiring connects directly to AC sub-panel with appropriate breaker! +Incremental growth capability - no need to purchase many expensive modules at one time. +Minimizes system design time and expense. +Significantly decreases system power reduction events due to single-module shading. +No large or heavy inverters to ship, handle, or mount. +Easy to install and service - PV panel and inverter are integrated into one unit. +No imbalance losses due to differences in PV output voltage or current. +Anti-islanding protection built into every module (per UL1741). +Microprocessor-controlled Maximum Power Point Tracking (MPPT) operates over entire DC input voltage range. +Eliminates series connection problems, where one defective component can affect entire system. +PV panel is not exposed to high voltage - eliminates arching problems.
