When you add backup battery storage to your low cost and energy efficient solar PV system, you'll gain a number of additional financial benefits.
During daylight hours solar panels collect solar power energy which is converted by a solar inverter into AC electrical current to be used in the normal way. During the night, the electricity supply can then be taken from stored renewable energy in your batteries, saving you the high priced peak power costs.
With an affordable solar battery back-up system you can easily store your valuable, excess daytime solar energy. This gives you the choice of feeding it back into the power grid to provide a credit on your electricity bill, or keep it for your own use during peak energy hours to save about 90% on your utility bill.
1 Solar Panels
Solar panels, or solar modules are usually installed on the roof. These solar panels are made up of photovoltaic (PV) cells, which convert sunlight into direct current (DC) power.
2 Charge Controller
Diverts solar power to our battery backup bank installed usually in your garage or outside of your home. A charge controller is a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery. Most “12 volt” panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging. Most batteries need around 14 to 14.5 volts to get fully charged.
3 Battery Backup
Excess solar power is stored in your battery backup system to be used at night, when rates are higher or in case of a power outage your battery backup system gives you unstoppable power 24/7.
The DC power from the solar panels is sent to an inverter, where it is converted into alternating current (AC) power, or standard electrical current used by your home. Your inverter in a battery backup system will draw power from your batteries when the power grid is down or for higher priced night-time utility rate periods.
AC power travels from the inverter to the electrical panel, many times called a breaker box. This power is now ready to use in your home.
6 Utility Grid
Your home remains connected to the utility grid to supply and excess power can be net-metered or sent to your battery backup system.
