Introduction

1.0 Introduction
Congratulations on your purchase of a MicroGT 500 inverter. This
microinverter is used in utility-interactive grid-tied applications, and
the microinverter system is comprised of two key elements:
1. A MicroGT 500 inverter
2. A MagWeb GT unit
Refer to Figure 1 for an example of a basic system installation
diagram using multiple MicroGT 500 microinverters.

MicroGT 500 microinverters maximize PV energy production
Each PV module has individual Maximum Power Point Tracking
(MPPT) controls, which ensures that the maximum power is
exported to the utility grid regardless of the performance of the
other PV modules in the array. When PV modules in the array are
affected by shade, dust, orientation, or any situation in which one
module underperforms compared with the other units, the MicroGT
500 inverter ensures top performance from the array by maximizing
the performance of each module within the array.
More reliable than centralized or string inverters
The distributed MicroGT system ensures no single point of system
failure exists across the PV array. MicroGT 500 microinverters are
designed to operate at full power at ambient outdoor temperatures
of up to 149°F (65°C)—see Appendix B – Effi ciency Curves (Figure
11). The microinverter housing is designed for outdoor installation
and complies with the NEMA 6 environmental enclosure rating.
