Advanced Energy AE 75TX Owner's manual

AE 75TX and AE 100TX
The industry standard for
reliability and ease of installation
The AE 75TX and AE 100TX commercial inverters set the
industry standard for high reliability, ease of installation, and
lifetime maintainability. Designed for a 20+ year operating
life, high reliability is enabled by busbar power connections,
redundant cooling system, and card cage circuit board
design resulting in a track record of 99+% uptime. With
a best-in-class efficiency of 96%, the highly integrated
system is designed to save installers time and money with
load break rated AC & DC service disconnects, neutral-free
installation, oversized busbar landings, and generous cable
bending area with bottom and side entry options. The wide
295-595 V operating window maximizes energy harvest
and provides exceptional stringing flexibility. The robust
construction of the AE 75TX and AE 100TX inverters allow
them to be applied in high DC loading applications, with
DC:AC load ratios up to 1.75:1 (see specification table for
details).
New features include remote disable inputs and an
expanded array of monitored subcombiner fusing options.
A 24 V auxiliary power supply, revenue grade meter, and
performance monitoring gateway can also be added for a
completely integrated inverter solution. Advanced power
controls provide essential utility support functions including
power factor, curtailment, and controlled ramp rate.
The AE 75TX and the AE 100TX are backed with an industry-
leading 10-year nationwide warranty and a comprehensive
optional 20-year warranty; plus the best service and support
team in the business.
