OFF-GRID SYSTEMS

1. Off-Grid Overview: How It Works

Living off-grid means your capsule operates independently from traditional utilities such as

electricity, water supply, and sewage systems.

 

Off-Grid Living Includes:

• Independent power (solar + battery + optional wind)

• Independent water (tank, AWG, desalination)• Independent water (tank, AWG, desalination)

• Independent waste systems (incineration or biodigester)

• Minimal monthly bills

• Greater sustainability & autonomy

 

How a Full Off-Grid System Works

1 Solar panels collect energy

2 Batteries store power

3 Inverter & microgrid controller distribute energy

4 Water system provides fresh water

5 Waste system handles disposal safely

 

Your Capsule Whales home becomes a fully self-sufficient living unit.
