MAX 180KTL3-X MV Grid-Tied Inverter

Product Overview

The MAX 180KTL3-X MV is a three-phase grid-tied inverter rated at 180 kW output for medium-voltage 277/480 V grid networks. It uses 10 MPPT inputs at 45 A maximum current, accepting up to 270 kW PV input at a maximum voltage of 1100 V. The MPPT operating range is 180-1000 V with a rated input voltage of 720 V and 600-850 V full-load range.

The output delivers 198 kVA maximum apparent power at 277/480 V nominal (408-528 VAC range) on a 3W/PE connection. Maximum efficiency reaches 98.80% with 99.90% MPPT efficiency. Class II DC/AC surge protection, RCD (GFCI), anti-islanding, string monitoring and optional Anti-PID and AFCI complete the protection set.
