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.
System equipment from $13,000 (excluding taxes, permits, installation and generator)
