How does the home battery work?
Solar panels are one of the best renewable energy sources, but they only generate energy when the sun is shining. That's where a home battery comes in handy.
Home batteries work by storing the electricity generated from the solar panels, or if there is overcapacity on the grid (for example, when a lot of solar energy is being generated), and using this stored energy later when electricity demand is high (for example, at night). evening when the sun has set).
There are two main types of home batteries: lithium-ion batteries and lead-acid batteries. Lithium-ion batteries are the most popular choice for home batteries due to their high energy efficiency, long life and safety. The LiFePO4 batteries are a variant of the Lithium-ion battery.
That is how it works:
1
The battery is connected to the inverter and the grid.2
When there is overcapacity on the electricity grid, this electricity is stored in the battery.3
When the electricity demand at home is higher than the generated power (for example in the evening), the electricity from the battery is used.4
When the battery is empty, the system automatically switches to the mains power.How do solar panels and home batteries work together?
There are a number of components that make up a home solar power system. Firstly, there are the solar panels, which supply energy to an inverter. The energy then passes through a switchboard where it is routed to the appliances in your home.
When the sun is not shining, the electricity grid steps in to maintain the power supply. If you generate more solar energy than you need, that energy goes back to the grid and you get a solar return rate as a credit to your account. In the near future, however, this will decrease or disappear completely due to the net metering scheme. Supplying back to the grid makes no sense in that situation, and is then very disadvantageous for you economically.
But if you have installed a battery system, the power station will divert the excess solar energy you generate to the battery so that it is charged for later use. When the sun goes down or when you consume more energy than your panels produce, the stored energy from your battery will power your appliances. And if your battery is empty, the electricity grid will help again.
Here is an example of how a home battery system works, where a battery is added to an existing solar system.
