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-inverter-based systems.

Advantages Over Conventional Grid-Tie Systems

50% reduction in wiring requirements! This eliminates:

• DC wiring
• DC cable trays
• DC fusing, overcurrent 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 point 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.
• Adaptable: J-box or Multi-contact connector input. Knock-outs for standard AC-side conduit fittings.
