What is Sunlit BK215 Zero Export?

The Sunlit BK215 is an innovative balcony power station storage system that uses LiFePO4 batteries and enables zero export. This function ensures that only the required solar power is fed into the grid, while surplus energy is stored and used for self-consumption. The storage system is easy to install and is particularly suitable for tenants and homeowners. DRBO Greenenergy offers this system in various versions for maximum efficiency.

What exactly is the Sunlit BK215?

The Sunlit BK215 is a compact storage unit with a capacity of 2.15 kWh and a continuous output of 2000W. It is specially designed for balcony power stations and can support up to 8 solar modules and a Deye inverter. The storage system uses zero export technology, which limits the injected energy to the required minimum, thus maximizing self-consumption. This function increases energy autonomy by storing surplus solar energy and using it later.

How does zero export work with the BK215?

Zero export with the Sunlit BK215 is achieved via a Shelly Pro 3EM or IR smart meter, which measures household consumption and ensures that only the required solar power is fed into the grid. The surplus electricity is stored in the battery, maximizing self-consumption. When the battery is fully charged, the user can choose between a bypass mode or strict zero export. DRBO Greenenergy recommends this solution due to its efficiency and legal compliance, as no additional grid feeding is required.

What are the advantages of zero export?

Zero export increases energy autonomy, as surplus solar power is stored and used as needed. This avoids strain on the power grid and saves costs at the same time. It is particularly noteworthy that no EEG levy or grid fees are incurred for exported electricity, which makes the system particularly attractive. In addition, it offers a significant reduction in electricity costs, as self-consumption is optimized up to 100 percent. DRBO Greenenergy emphasizes that customers can achieve a payback period of less than 3 years with this technology.

Can the Sunlit BK215 be expanded?

Yes, the Sunlit BK215 can be expanded to a capacity of up to 8.6 kWh. This is achieved by integrating additional storage modules and supporting up to 8 solar modules. The storage system is future-proof, as it can keep pace with increasing energy demands such as operating an electric car or a heat pump. DRBO Greenenergy offers suitable expansion kits that are compatible with the existing system, so installation can be done easily and without the help of an electrician.

Can zero export be set up without an electrician?

Yes, zero export can be set up without an electrician. The IR smart meter or the Shelly Pro 3EM is simply attached to the meter, and configuration is done via an app in a few minutes. The process is particularly simple and user-friendly thanks to the plug-and-play system. DRBO Greenenergy provides comprehensive instructions and videos to assist customers with installation. The system is compatible with all common meters, and legal requirements are easily met if the export limits are observed.

What efficiency does the BK215 achieve?

The Sunlit BK215 achieves an impressive efficiency of over 95 percent at a continuous load of 150W. The high efficiency ensures that only minimal losses occur during the charging and discharging phases, which further optimizes the system's energy efficiency. The LiFePO4 batteries of the storage system enable more than 6000 charge cycles and thus guarantee a long service life. DRBO Greenenergy ensures that every device is tested before delivery to guarantee the highest quality and efficiency.
