What is the Sunlit BK215 connection diagram and how does it work?

The Sunlit BK215 is a versatile balcony power plant storage unit with 2.15 kWh capacity, expandable up to 8.6 kWh with additional B215 modules. With two PV inputs, a bidirectional inverter, and easy plug-and-play installation, it enables tenants and homeowners to efficiently utilize solar energy. DRBO Greenenergy integrates this storage unit into customized complete solutions for sustainable energy supply and maximum self-consumption rates.

What exactly is the Sunlit BK215?

The Sunlit BK215 is a compact lithium-ion battery storage unit for balcony power plants, capable of storing 2.15 kWh of electricity. Its IP65 protection makes it weatherproof, while its bidirectional function stores surplus energy and releases it when needed. DRBO Greenenergy offers compatible solutions for easy integration into existing solar systems. The BK215 operates with high efficiency, over 95% effectiveness, and allows monitoring via an app. It is compatible with common inverters like Deye or Hoymiles and is suitable for balconies, terraces, or carports. With two PV inputs, up to four solar modules can be connected, optimizing the self-consumption rate.

How does the Sunlit BK215 connection plan work?

The connection is modular: first, place the basic BK215, then stack up to three B215 extensions. After that, mount the bidirectional inverter (e.g., EV3600) and connect the PV cables. The grid connection is made via a Schuko output. All cables use MC4 connectors for plug-and-play convenience. DRBO Greenenergy supplies compatible accessories and cables. Installation usually takes about 30 minutes.

What is the compatibility of the Sunlit BK215?

The BK215 supports Deye, APsystems, Hoymiles (with OpenDTU), and EV3600 inverters with two outputs. Up to four modules of 400 Wp each can be operated in parallel. DRBO Greenenergy combines the storage unit with plug-and-play packages including solar modules and mounting brackets. Compatible apps enable real-time monitoring of charge status and yield, while VDE-AR-N 4105 certification ensures grid-compliant feed-in.

Why is the Sunlit BK215 expandable?

Up to three B215 extensions can be connected in parallel, creating a total capacity of 8.6 kWh. The modular design allows for gradual growth according to solar yield. DRBO Greenenergy offers refurbished versions with Deye inverters, promoting sustainability. With over 6,000 charge/discharge cycles and a lifespan of 10 years, the BK215 is ideal for households with 5–10 kWp PV output and saves up to 50% in costs compared to fixed storage systems.

What advantages does the Sunlit BK215 offer?

The BK215 impresses with easy installation, high flexibility, and app-supported monitoring. Self-consumption rates of up to 90% reduce electricity costs by 300–500 € annually. DRBO Greenenergy integrates the storage units into weatherproof and low-noise complete systems. Bidirectional inverters increase energy efficiency, while positive customer reviews (Trustpilot 4.6/5) confirm reliability. Ideal for tenants and owners looking for a simple plug-and-play solution.

How to safely install the Sunlit BK215?

Stack the storage unit on a level surface, check cables, and use an RCD. Configure the app before connecting to the grid, wear gloves, and avoid short circuits. DRBO Greenenergy offers suitable mounting brackets and accessories. Observe VDE standards: keep voltage below 60 V DC, perform regular app maintenance. An electrician is only required for earthing.

How to set up the Sunlit BK215 App?

Download the app, add the device, connect Wi-Fi to the inverter, and set parameters. Set the charge limit to 95% and discharge to 20%. DRBO Greenenergy supports intuitive apps for consumption analysis, displaying charge status, yield, and performance data in real time.
