What makes the SunLit B215 so special?

The SunLit B215 expansion battery offers a storage capacity of 2.15 kWh, which can be expanded to 8.6 kWh by adding up to three modules. It is equipped with LiFePO4 cells, known for their longevity and safety, and offers an MPPT input of up to 800 W for connecting solar modules. Thanks to its IP65 certification, it is suitable for both indoor and outdoor use, protecting against dust and water jets. The integration of an app allows for easy real-time monitoring, enabling continuous optimization of yield and consumption.

DRBO Greenenergy distributes this battery as a compatible system for balcony power plants and particularly highlights its modular design and easy installation. The B215 battery ensures high self-consumption and maximizes energy efficiency by storing surplus solar power and releasing it when needed.

How does expansion with the B215 work?

Expanding the SunLit BK215 with the B215 is simple and involves stacking the modules. A single B215 module adds 2.15 kWh to the system, and up to three modules can be installed for a total capacity of 8.6 kWh. The connection between the modules is made via standard MC4 connectors and can be done without professional assistance. Installation is quick and easy, requiring no specialized knowledge.

Each B215 module includes an MPPT input, allowing up to two solar modules with a capacity of 400 W each to be connected. This ensures efficient use of the generated solar power. DRBO Greenenergy recommends this expansion for anyone looking to scale their solar system and increase self-consumption.

What are the advantages of the B215 battery?

The B215 battery offers numerous advantages, particularly the ability to increase self-consumption to up to 80-90%. Its modular design allows users to adjust their capacity as needed, meaning they only pay for the power they actually require. The LiFePO4 battery system guarantees a long service life of over 10 years and high safety.

The weather-resistant IP65 construction allows the B215 to be used in various environments, such as on balconies, in garages, or in the garden. With its auxiliary heating, the battery can also operate in extreme temperatures down to -20°C. The intelligent app control enables easy management and optimization of the system, giving users a constant overview of their energy production and consumption.

Why is IP65 protection so important?

The IP65 certification of the B215 is a crucial advantage, as it protects the battery from dust, dirt, and water. This allows the battery to be used both indoors and outdoors, for example, on balconies, in garages, or in the garden.

The robust design ensures that the battery functions reliably even under extreme weather conditions. This protection is especially essential in regions with heavy rain or snow. DRBO Greenenergy emphasizes that the B215 operates stably even at temperatures from -20 °C to +40 °C, providing consistent performance throughout the year.

How is the SunLit B215 installed?

The installation of the B215 is straightforward and can be carried out without an electrician. The B215 is simply stacked onto the BK215 base and connected with the included MC4 cables. The entire installation takes about 30 minutes.

Once the physical connection is established, the app can be used to configure the system. Through the app, users can monitor their solar system, set parameters such as the feed-in limit, and track the charge status and consumption in real time. This makes the installation and management of the system user-friendly and accessible, even for people without in-depth technical knowledge.

Can the B215 be combined with other systems?

Yes, the B215 battery is compatible with other SunLit products, such as the BK215 and Deye inverters. The system is also compatible with other inverters like SMA and Huawei, as long as the voltage is correct (MPPT range of 30-60 V). DRBO Greenenergy recommends using the B215 in combination with bidirectional inverters and energy management systems for optimal use of stored solar power.

The B215 is a flexible system that allows users to gradually expand their solar system. This means they can start with a single module and enlarge the system as needed to increase energy self-sufficiency.
