SunEnergy XT BK215 Plus – Storage Power Plant

Maximize the performance of your balcony power plant or solar system – with the SunEnergyXT Storage BK215 Plus

One of the most powerful storage power plants in its class

Use more solar power yourself. Waste less.
The SunEnergyXT BK215 Plus stores your solar energy exactly when it is generated – and makes it available to you exactly when you need it. Whether in the evening, at night or on a cloudy day: your energy belongs to you.

With a storage capacity of 2,150 Wh, your balcony power plant becomes a real energy system.

Modular. Scalable. Future-proof.

The BK215 Plus is the starting point of your energy independence
Thanks to its clever, modular design, you can expand the system at any time – without any modifications or technical expertise. Simply plug in additional modules and you're done.

➡️ Up to 8.6 kWh storage capacity – if you want it.
➡️ Up to 4 kW PV input power – significantly more than conventional balcony storage systems. This allows the system to grow with your needs.

Performance that inspires

The BK215 Plus delivers power:

• Up to 2400 W output power including bypass function
• 2 MPP trackers for maximum energy yield – even with partial shading
• Elegant front display with real-time display of charging and discharging power

You can see at any time what your system is doing – and it does a lot!

Everything at a glance – anytime, anywhere

Special feature: Enhance Module EV3600

In addition to the option of charging an electric car and 2x Schuko sockets as emergency power sources, the Enhance Module EV3600 also offers the option of charging the battery directly with mains power.

This is a highly interesting option, especially for dynamic electricity tariffs such as Tibber. Electricity prices are usually significantly cheaper at night or for 2-3 hours in the late afternoon. Fluctuations of more than 20 cents / kWh and more on the same day are not uncommon. With the EV3600, you can charge mains power at favorable times and use it exactly when the electricity price is high again.

Charging an electric car is possible up to a power of 3.68 kW from battery/solar power (1-phase). In mixed operation with 3-phase mains power, up to 11kW is possible. If battery charge and/or fed-in solar power are sufficient, about 1/3 of the electricity is drawn from the battery or solar in 3-phase operation, the remaining 2/3 from the public power grid.
