Sonnen is definitely one of the leading solar energy storage solutions manufacturers in the entire market, a direct competitor of Tesla or LG. However, unlike the other two brands, Sonnen does not only focuses on improving manufacturing procedures to reduce costs. Instead, Sonnen addresses a selective market who wants the best performance, best features and also the best warranty which adds a premium price unlike any other.

This solution is a household energy storage system based in lithium-iron phosphate (LiFePO4) technology intended to store energy from a personal photovoltaic system. This makes the client more independent from the utility grid to reduce energy cost, or to achieve a complete off-grid application if desired.

There are mainly three products available from the brand which we can visualize below


Sonnen offers three different choices to fit the client needs. Which should you choose? Let’s analyze the features of each one of them.

The sonnenBatterie eco and hybrid have a warranty of 10000 charge cycles or 10 years of premium warranty (whichever comes first). They are also “ready to connect” with a storage capacity ranging from 5 kWh to 15 kWh (individually expandable in blocks of 2.5 kWh post installation). This is meant not just to fulfill a detached house but a multi-family house as well.

Every sonnenBatterie offers a completely integrated solution that includes PV inverter and battery storage all-in-one. In other words, besides the sonnenBatterie, all that you need are the PV modules, the wires, and the combiner box.

Moreover, you will also enjoy an intelligent energy manager, measurement and software technology to operate the system smoothly. High quality is the main standard from the brand which allows you to enjoy a high-quality casing that ensures a long lifespan and the best quality from German technology.



The sonnenBatterie can also be easily integrated with a number of accessories to improve the client's experience even more and optimize the further increase in consumption. 


Sonnen is the top quality energy storage brand in the market. By purchasing one of these products you will be enjoying the battery storage solution with the highest reliability, standards, and warranty of the market. 

Maybe one of the most attractive factors about choosing a PV system with a sonnenBatterie is that there will never be a compatibility issue between your battery and the inverter model since it is a complete integrated solution.
