Sonnen batteries for solar panels: a smart storage solution

Saving 90% on your electricity bill is possible by installing solar batteries on your roof, regardless of:

• If you are thinking of switching to self-consumption,

• or if you are already taking advantage of the benefits of a photovoltaic system.

Sonnen batteries are the right choice if you are looking to increase your economic savings and be more sustainable.

Because of this and because you reduce your dependence on the conventional electricity grid.

Thanks to the solar accumulators you can take advantage of the energy produced with your system when sunlight is not available.

If you are looking to add a storage system to your home, in this article we are going to explain the characteristics of these accumulators. In addition, we will go into more detail on the following points:

• Which Sonnen solar batteries we use.

• If they have a backup function or emergency exit.

• How much it costs to install this type of battery.

• Advantages of choosing Sonnen batteries on your roof.

Which Sonnen batteries do we use at SolarMente?

Solar batteries accumulate energy during the hours of peak solar radiation to consume that energy when it gets dark.

Our aim is that you can opt for components that cover your energy needs when the solar panels are not in operation and, for this reason, one of the options we work with is the German manufacturer Sonnen.

Mainly for several reasons:

• Good energy efficiency

• Maximum safety

• Long service life

In addition, their elegant and simple design fits perfectly into the home.

And another of its strengths is that it is a complete system, i.e. it does not require any additional components in the installation. This means fewer errors when it comes to commissioning.

The company offers 3 types of batteries and, from SolarMente, we use:

• SonnenBatterie 10

• SonnenBatterie 10 performance

Although there are various capacities available, we use the 5 kWh and 11 kWh.

As a general rule, households do not require capacities higher than 10 kW. However, it is worth noting that the company has solutions with higher capacities available for households with higher consumption.

We will now show you the characteristics of each model.

SonnenBatterie 10

The sonnenBatterie 10 does not allow the wiring of direct current and acts as an additional consumption of the house.

But the good thing is its intelligent storage system that maximises the use of the energy that arrives at your home.

Also, the manufacturer suggests placing the system in a walkway or in the garage itself, rather than in other installations such as, for example, the living room.

Why is that? Its forced ventilation.

In the same way as a computer, it makes the same ventilation noise. For this reason, it is advisable to avoid installing it in rooms where we spend a lot of time and to leave a space of 10 cm at the bottom for proper ventilation.

On the other hand, it has a powerful charging and discharging performance of up to 4.6 kW.

In short, the sonnebatterie 10 is ideal for adding to any existing installation as they are compatible with all inverter models.

SonnenBatterie 10 performance

Unlike the previous model, the SonnenBatterie 10 performance is designed for three-phase systems.

Therefore, it is a solution with more power and capacity. Specifically, we are talking about modules with storage capacities from 11 to 55 kWh.

In what situations is it convenient to opt for this model?

It is an interesting solution for households with a large energy consumption. For example, if you have an electric car or an aerothermal system.

Do Sonnen batteries include a backup function?

The short answer is yes.

The entire range of Sonnen batteries offers the backup box function or emergency exit through the incorporation of a new element: the SonnenProtect.

In other words, this function allows you to enjoy electricity in the event of a power failure.

In any case, each design includes a specific SonnenProtect model:

• SonnenProtect 4000: this is the emergency solution for the SonnenBatterie 10. Within a period of 5 seconds, it provides limited power via a dedicated circuit.

• SonnenProtect 8000: is the backup function for the SonnenBatterie 10 performance. Used for three-phase installations with 8 kW power. It can withstand overloads of up to 5.5 kW for 5 minutes and 8.8 kW for 11 and 22 kWh capacity.

Advantages of installing a Sonnen battery in your home

The flexibility and adaptability of these batteries have made the German manufacturer one of the highest quality systems on the market.

Why choose Sonnen?

Here are the main advantages:

Versatility

Let’s start with its most outstanding feature: versatility.

This design has no problem adapting to the different self-consumption needs of a home.

Whether it is a new installation or if you want to add batteries to your solar panel system, the brand has solutions for everything.

In the case of needing more power, it will not be a problem either. It has options for single-phase and three-phase installations, not only for homes but also for companies with higher energy demands.

What other alternatives does it provide?

Emergency systems.

Each model has a device called SonnenProtect. These components guarantee the availability of light in the event of a power cut.

Finally, it is worth mentioning its two operating modes:

• Prima maximising self-consumption, storing the surpluses generated or using the surplus energy to charge electric cars or even for an aerothermal system.

• Time of use. This mode allows you to define charging and discharging times, establish charging priorities or power, among other things.

Intelligent storage management

Intelligent storage management refers to the system’s ability to understand and control energy flows to ensure maximum self-consumption for your home.

But not only this.

The intelligent system allows you to know the weather forecast up to 3 days in advance, which allows you to manage the energy and even when it is charged and discharged for superior optimisation of your domestic consumption.

We add an extra bonus: its artificial intelligence.

Over the last year, technology has taken giant leaps forward, and in solar energy it is no exception. That’s why this system learns your consumption habits.

And why is this of interest to you?

Precisely to improve the efficiency of your home and extend the useful life of the equipment.

In addition, the algorithm can detect if the battery is about to reach its maximum capacity to adjust the charging power. In short, it achieves a longer service life.

The warranties

Its LFP technology, i.e. lithium iron phosphate, makes the systems safer and more durable.

For the same reason, it offers a 10-year warranty 0 10,000 charge cycles performed. This is within the timeframe of the other manufacturers we work with.

They guarantee a storage capacity of at least 70% after the guarantee period.

Compatibility with inverters

If you already have a photovoltaic installation, it does not matter what brand your inverter manufacturer is, because these batteries do not communicate with this device.

Let us explain.

The function they perform is to measure the alternating current energy coming out of the inverter and the connected output. In short, this means that it is compatible with any manufacturer, as it is controlled independently of the installation.

And this is one of the most outstanding features of the brand.

Therefore, you can always install a Sonnen battery in your home. In our case, those installations that have Huawei or Fronius inverters, will have the possibility of installing a battery from this company.

Price of Sonnen batteries

It is clear that a system that includes solar accumulators does not have the same price as if we opt only for installations with solar panels. The investment to be made is higher.

But the truth is that the household electricity bill is significantly reduced, up to 90%.

And Sonnen batteries offer us total versatility, from the inclusion of an inverter in the battery itself to its compatibility with the remaining inverters on the market. In other words, its adaptability is clear.

It remains a successful energy solution because of its durability, compatibility and the other advantages mentioned in the previous section.

The cost of the batteries also varies depending on the capacity of the batteries and their characteristics.

The prices of Sonnen batteries vary depending on the power and features. Broadly speaking, we show you the cost of the capacity we use:

Increase electricity savings with Sonnen Batteries

Sonnen batteries are an excellent choice for adding lithium batteries to a new or existing installation. They are compatible with all inverters on the market and offer numerous advantages to your solar system.

Now that you know the main features of these batteries, you can make an informed decision.

If you have a high consumption and want to maximise your electricity bill savings, adding batteries to your photovoltaic installation is an option that will probably be of interest to you.

Instead of dumping surplus energy production, a battery will allow you to make the most of surplus energy.
