How does off-grid solar storage work?
Using off-grid solar storage 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.
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.
