The success of any off grid homestead starts with the design of your home! Part 2 addresses further this concept. Today Starry talks about HEATING the house and the beauty of the thermal mass and their woodstove! AND not only the heating, but FREE air conditioning!!! A Passive solar design takes advantage of a building’s site, climate, and materials to minimize energy use. A well-designed passive solar home first reduces heating and cooling loads through energy-efficiency strategies and then meets those reduced loads in whole or part with solar energy. Passive design is practiced throughout the world and has been shown to produce buildings with low energy costs, reduced maintenance, and superior comfort. DO not overlook this key point when going off the grid. IF YOU have the opportunity to design and build your own home…THINK before you build.
Starry shares how they incorporated into their design passive solar and thermal mass!

Discussed in this video is how a regular grid tie solar power system works when the grid is up and when it’s down, and what some of your options are when the grid does go down.
- Limitations of a Grid-tie Inverter
- Dealing with power outages
- Adding battery backup to your Grid-tie Solar System
altE Store has made adding battery backup to your grid tie solar power system easy by designing some AC Coupling kits for you to add backup to your grid tie system. We can work with you to determine which kit is right for your needs, or if you need a custom designed kit.
AC Coupling Kits include:
- Hybrid Inverter
- Batteries
- Battery Box
- DC Breakers
- Control Panel
