We used Polygon in the selection and installation of a battery for our home in regional NSW. Excellent customer service and professional advice on what unit was best for us.

Bhavin designed the best system compared to other providers. This included upgrading the 3 phase which optimised everything. Great team of people. They delivered what I hoped for and the system has been running well. Very pleased and saved loads on electricity in first year.
