Brief Introduction

MRac Ground Terrace IV, a newly-updated ground solution on the base of Ground Terrace III, is specially developed for middle-large PV ground projects. With its high structural strength and stability, the highly pre-assembled solution can freely adjust to areas in extreme environments with an all around adjustment, greatly reducing the precision requirements of system installation. What’s more, the structural designs save time and labor cost.
