A solar battery system allows you to take full advantage of the solar energy produced by your rooftop solar panels. Having a backup solar battery bank makes you self-sufficient, reduces your carbon output and saves you from soaring power bills, especially during peak periods.
So How Does a Solar Battery Work?
Typically, in a solar power system, the solar panels generate and supply power to your appliances during the day. And it exports the excess energy generated during the day to the grid.
When there is a shortfall, usually during early mornings, evenings, nights and in cloudy weather, energy is imported from the grid with the help of an inverter to meet the energy requirements. Moreover, whenever there is a grid blackout, the inverter turns off, and most home solar power systems also shut down.
But by installing a solar battery to your existing solar power system or a new solar panel and solar battery system together, you eliminate the need for importing electricity from the grid. The right solar power system with enough solar batteries makes you less dependent on the grid by preventing importing electricity from the grid.
So, let’s see how a solar battery actually works. If you have solar batteries, the excess energy generated during the day is not fed into the grid but is used to charge the solar battery. Some solar batteries can also charge from the grid during off-peak times, typically overnight (when electricity prices are the cheapest).
The solar batteries then store the surplus energy produced by the solar panels for later use. This energy is also used whenever there is a surplus need for energy at home, more than the energy generated from your solar panels. Thus, solar battery bank systems can power your household appliances without importing power from the grid. Lithium-ion batteries are the best solar batteries available on the market today. They have a longer lifespan, occupy less space and are easy to maintain.
What Happens When Solar Batteries Are Full?
You may wonder what happens when the solar batteries are in full charge because a constantly overcharged system affects the battery life. Not to worry, when the batteries become fully charged up, the excess energy is fed back to the grid.
And in the case of off-grid solar systems, you have battery monitoring systems and charge controllers that protect the batteries by redirecting and managing the energy flow. Some batteries and inverters also have displays that indicate the battery status. However, if your batteries become regularly full, you may need to purchase additional batteries for storage, or an accredited solar installer will be able to help you with that.
How To Use Solar Batteries Effectively?
Many households have typical energy consumption during evenings and nights. With a bigger battery bank system, you could efficiently manage all your energy needs without relying on the grid.
One way to effectively use solar batteries is by running appliances with large electrical loads, such as washing machines, dishwashers, and hot water service, during the day instead of at night. This prevents solar batteries from depleting completely and improves their life.
Having the right system is crucial to make the most use of your solar batteries and solar panel system. With the advancements in solar technology, we have various solar energy storage options available today.
