The Retreat - SW

4kW Off-Grid Cabin Power Package


Your Retreat Power Solution

“The Retreat” is the perfect power solution for those who need to get-away without forgoing the amenities of civilized life. In power terms, The Retreat is capable of powering everything except resistive loads (ovens, toasters, hair-dryers, baseboard heaters etc).

Occasional automatic cycling of a sound-dampened generator during programmed non-quiet times allows for drastically reduced fuel consumption and noise pollution compared to standard generator-only power solutions.

From $12,995 Taxes, permits, installation and generator not included.
