Emerald Lake State Park is a 430-acre state park in East Dorset, Vermont. Historically grid-tied, the power lines running through the park’s woods required repair after each winter. To solve that problem, park authorities decided to switch to a reliable off-grid system.
Grassroots Solar designed and installed the microgrid. It features 10.24kW of SolarWorld modules, an OutBack 8000W 48V inverter, and 24 PHI 3.4 48V batteries, providing 81.6kWh of storage. The microgrid powers cabins for park staff, bathrooms and camper services for park guests.
“We needed a battery that could not only survive in below-freezing temperatures but also deliver high performance in those tough conditions,” explained Bill Laberge of Grassroots Solar. “Given our space constraints, we also needed a battery that could be racked. PHI batteries provided the ideal solution.”
