Everything you need to know about solar batteries

Do you know that 70% of the energy produced by your plates is lost? Only 30% is consumed by the household, the rest is returned to the conventional electricity grid. This is why the batteries for solar panels they become a very valuable complement to your self-consumption installation. Discover all the benefits of batteries, and how they can make your home more self-sufficient.

What are solar batteries?

The solar battery is a storage device that accumulates the energy produced by solar panels. A tool that makes your photovoltaic installation more profitable, since it allows you to use accumulated energy when you need it. With them, energy, which is not consumed, does not go to the electrical grid, but is stored for later use.

How do solar batteries work?

First of all, to be able to have a solar battery, you have to have solar panels in your home. The batteries are connected to this installation, allowing that energy that is not being consumed to accumulate in the device. With this process, we prevent unused electricity from returning to the conventional electrical grid, and, on the contrary, being kept in the home.

The batteries are charged with this excess energy, and they accumulate it in their space until they reach their maximum. This is why depending on the amount of energy your plates produce, you should use a battery with more storage power or less. To choose the option that best suits your needs, we recommend that you talk to our experts in self-consumption.

Thanks to its functionality, a family can consume energy produced by their installation regardless of schedules. In other words, with solar batteries it is not necessary to change energy consumption habits.

Advantages of solar batteries

Household batteries add value to the installation of plates, but first and foremost cost-effectiveness. In this space, let's summarize the advantages of batteries:

1. More efficiency in your installation: thanks to batteries, the energy production of solar panels is used exponentially, avoiding the loss of unconsumed electricity.
2. Total freedom of time: you will never have to worry about consuming energy at night or at times when the The price of electricity is at its maximum. With the battery, all the energy you consume is yours.
3. You should not change your consumption habits: if you are a night person, once the battery is installed, you don't have to change your habits, since the electricity you are going to consume is self-produced by your installation.
4. They take up little space, but their utility is immense: household batteries don't take up much space thanks to their compact and simple design, making it easy to place them at home. Even its size, its function is essential to complete a self-sufficient home.

Maintenance and care of solar batteries

Good care for the installed solar battery is key to making it last as long as possible. The batteries offered by Eltex have a lifespan of 20 years, however, the use or maintenance they receive may minimize their functionality.

An important factor affecting the battery is temperature. It is necessary to maintain an ambient temperature between 20 and 25 degrees, avoiding strong variations, since it directly influences the useful life of the device.

On the other hand, we do not recommend discharging it to less than 80% continuously, since this practice drastically reduces battery functionality. To avoid this situation, we recommend that you install a battery with sufficient capacity and configure the inverter so that this does not happen.
