SunEnergyXT BK215 PLUS

The SunEnergyXT BK215 PLUS is a powerful, modular battery storage system for balcony power plants and small PV systems. It was developed to efficiently store self-generated solar power and use it at different times - exactly when you need it.

More independence from the power grid

Excess solar energy is automatically stored during the day. The storage unit makes the electricity available again in the evening, at night or when there is little sunlight. This reduces grid consumption, lowers electricity costs and noticeably increases your own consumption - without complex installation.

Compatible & flexible to use

The BK215 PLUS is compatible with common microinverters such as APsystems and Deye. Two solar modules can be connected per PV input, in series or parallel depending on the module configuration.

Output power up to 2,000 W at 2.15 kWh
Up to2,400 W from 4.3 kWh storage capacity

Compliance with the applicable legal performance limits for balcony power plants must be observed.

Modularly expandable up to 17.2 kWh

The basic module with 2.15 kWh can be combined with up to 7 expansion modules. The modules can be stacked or mounted next to each other to save space. This means the storage grows step by step with your energy needs - without changing the system.

Intelligent zero feed-in

In conjunction with a suitable energy measuring device, the storage device dynamically adapts its performance to the actual house consumption. Surpluses are not fed into the public grid. The following are supported, among others:

Shelly 3EM / Shelly 3EM Pro
Bitshake IR reading head (Tasmota)
EcoTracker

Expandable to include AC charging & additional functions

With the optional SunEnergyXT EV3600 module the memory can also be charged via a normal 230 V socket. This means, among other things, The following applications are possible:

AC-coupled storage of PV surplus
Use of dynamic electricity tariffs
Local emergency power supply
Integration into wallbox and energy management systems

Full transparency via app

The SunEnergyXT app provides real-time insights into charge status, energy flows and history. Settings can be easily adjusted remotely - for maximum control over your solar energy.

Suitable for indoor and outdoor use

Thanks to IP65 protection class, the BK215 PLUS is reliably protected against dust and splash water and can be used outdoors without any problems.

BK215 PLUS als Basis des modularen Speichersystems

Der BK215 PLUS bildet den Kopfspeicher des PLUS Systems. B215 PLUS Erweiterungsspeicher ergänzen die Kapazität, ohne dass Du das Grundsystem wechseln musst.
