Off-grid solar electricity is for homes that do not have access to grid electricity -i.e the house cannot be or chooses not to be supplied electricity from a power company. These systems offer complete autonomy and independence from the national grid and power companies, meaning you never have an electricity bill.
Simply sun shines on solar PV panels on your roof or mounted near your house. These panels generate electricity which is used to power your home and charge your batteries. The batteries allow you to store electricity for use at night or times of low production like cloudy days.
Solar PV panels mounted on your roof or near your house capture energy from the sun and convert this energy into DC electricity. A Solar Inverter converts this DC electricity into 230V AC electricity. The main switchboard takes electricity from the solar inverter or battery inverter and sends it to power your home. The battery inverter is two way and can take surplus electricity from the main switchboard and convert in into DC electricity to be stored in batteries or demand is their convert stored DC electricity from the batteries into AC electricity to power your house.
