We were super Blessed with the opportunity to work on on the east end of Moloka‘i. We replaced 4 non working inverters with a single limitless 15k and 2 six stacks of powering 2 rental cabins and the Lodge annex. We were able to use the existing PV array which provides a little more than 17,000 watts of solar input. The professionals at Mattos Electric LLC were able to complete this clean install. And enjoy the beauty Moloka‘i has to offer. Big Mahalo to of Solark and of homegrid for this real time assistance. Also , , and from Mattos electric for the fast and clean work. We look forward to working towards a sustainable future with the ranch and the island of Moloka‘i. Please let me know if you have a home or business that you’d like to take off grid.
