Off-Grid Living

Off-grid living is becoming an increasingly viable choice for those looking for an eco-friendly way to live self-sufficiently. Best of all, using off-grid power systems allows you to have all the convenience that electricity offers without having to run power lines out to a remote property that may be prone to outages.

As of 2013, current estimates are that 1.7 billion people in the world live off the grid. According to Home Power Magazine, at least 180,000 families are living off the grid in the United States and that number increases each year. Living off the grid requires sustainable living. So you’ll need to find your own source of heat and electricity without the help of our modern-day conveniences. Solar power is the most popular and available option when it comes to off-grid energy.


How does off-grid solar storage work?

Solar panels first convert solar energy or sunlight into DC power using what is known as the photovoltaic (PV) effect. The DC power can then be stored in a battery or converted by a solar battery inverter into AC power which can be used to run home appliances.
