A solar battery will also be necessary, to allow your home to continue to run after the sun goes down. Throughout the day, your solar storage device will charge as your panels generate excess electricity. Rather than simply losing out on all of that available solar power, a battery enables you to keep it for use at a later time. Depending on your energy needs, you may have a single battery, or even a battery bank.
In order to convert the direct current (DC) collected by your solar panel array into the alternating current (AC) required to run most of your common household appliances and electronics, your solar power system will also need a solar inverter – sometimes referred to as a solar converter or a PV inverter. For the purposes of an off-grid system, you will likely use a stand-alone inverter, though there are a few options when it comes to set-up.
