How does the SunEnergyXT BK215 work?

The SunEnergyXT BK215 stores surplus solar power in a 2.15 kWh LiFePO4 battery and releases it when needed, such as at night or on cloudy days. Two MPPT trackers optimize the PV input power up to 1600 W and maximize efficiency. With the help of the app, operation can be monitored in real time and a zero-waste strategy can be activated, further optimizing self-consumption. DRBO Greenenergy offers this storage unit as a scalable SunLit solution that increases self-consumption to up to 80% and thus promotes energy independence.

What are the efficiency features of the BK215?

The SunEnergyXT BK215 boasts a discharge efficiency of 83.5% at 800 W load and 73.4% at a base load of 150 W. These values are comparable to the best competitor models and result from precise MPPT trackers and optimized cell performance. The DRBO Greenenergy app allows dynamic adjustment of power feed-in and minimizes losses, making the storage unit even more efficient. With a lifespan of more than 6000 charging cycles, the capacity is maintained long-term, leading to significant savings.

Why is self-consumption so high?

By storing surplus solar power, self-consumption is increased to up to 80%. The BK215 prioritizes meeting household electricity demand, enabling maximum self-sufficiency. Intelligent control via the SunEnergyXT app recognizes consumption patterns and discharges precisely to save grid electricity. Users can save €500–1000 annually as less electricity is drawn from the grid. These savings make amortization of the system possible within 3 to 5 years.

How to expand storage capacity?

The storage capacity of the BK215 can be increased to up to 8.6 kWh by connecting up to three B215 extensions. This is done via a tool-free plug connection, which allows for easy expansion. This modular design can be flexibly adapted to growing PV yields, making the storage unit ideal for households and commercial applications. DRBO Greenenergy offers customized configuration packages that include solar modules and inverters to ensure optimal efficiency.

What role does app control play?

The SunEnergyXT app offers real-time monitoring and optimization of energy feed-in. It allows control of day/night feed-in and supports the integration of smart home systems. Through the app, zero-waste strategies can be activated, which automatically limit voltage and analyze power consumption. This is particularly advantageous with dynamic tariffs, as it minimizes costs. DRBO Greenenergy recommends using the app to make energy management even more efficient, especially for tenants and homeowners.

Is the BK215 weather-resistant?

Yes, the BK215 is standardized to IP65, protecting it from dust and jet water. The integrated heating function ensures that the storage unit operates reliably even in cold weather, down to -20 °C. LiFePO4 cells remain efficient at temperatures from -20 °C to 55 °C without compromising performance. DRBO Greenenergy ensures that the BK215 is ideal for use on balconies, terraces, or in garages, without the user having to sacrifice performance.
