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-inverter-based systems.
PV AC MODULE
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 diodes
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.
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 located in the
right-hand compartment. (Conduit and
fittings not shown are customer/installer
provided.)
