Beer Brewed by the sun

Client
Monhegan Brewing

Year

We installed 20 Silfab 420’s, a hybrid 15k Sol-Ark inverter and a 30kWh Discover Battery system.

The system is able to detect any dips or jumps in the grids frequency. This allows the brewery to always maintain power in a blackout or a brown out. This was imperative for the Brewery so they can stay open in an outage but also not lose power while brewing a batch of beer.
