The article TSUN DCU2000Lite: The new generation of solar storage for balcony power plants from Powerness first appeared in the online magazine BASIC thinking. With our newsletter UPDATE you can start the day well informed every morning.

Powerness brings one with the TSUN DCU2000Lite modular, plug-in solar storagewhich makes balcony and small PV systems significantly more efficient. Practical: Customers can pick up the device themselves at eight locations in Germany and thus save on shipping costs. We’ll show you everything you need to know about solar storage.
The TSUN DCU2000Lite from Powerness is a plug-and-play solar storage system that was specifically designed for balcony power plants and small PV home storage systems. It combines long-lasting industrial battery cells with a modular, wireless stack design, creating a flexible storage solution that can be easily retrofitted.
Powerness offers the storage individually and in preconfigured sets with microinverters and bifacial solar modules – ideal if complete packages that are ready for immediate use are desired.
What sets the TSUN DCU2000Lite apart
Technically, the TSUN DCU2000Lite offers a number of features that make it attractive for balcony power plant owners:
- 314 Ah industrial battery cells for long service life and reliability;
- Modular stack design (wireless) – storage sizes from 2 to 10 kWh possible;
- 2400 W PV input with dual MPPT for optimized solar yield, even in partial shade;
- Compatible with around 99% of all microinverters — retrofittable and flexible;
- IP65 housing and app control – suitable for indoor and outdoor installation.

Why the device is particularly useful for balcony power plants
Many balcony power plants produce significantly more electricity during peak hours than can be consumed directly. The TSUN DCU2000Lite stores excess energy and makes it usable – in the evening, when it is cloudy or when consumption increases briefly. The dual MPPT inputs allow the optimal use of separate module strings (e.g. with different orientations or partial shading). The modular stack design allows you to start small and add capacity later.
Installation, compatibility and use
The storage is designed as a retrofit solution and can be coupled with common microinverters. Thanks to the plug-and-play approach, no complex modifications are necessary – for many users, simple installation and commissioning via the app is sufficient. The IP65 protection extends the possible uses to protected outdoor areas, such as balconies with a roof or terraces.
Pick up from Powerness – save costs and get started straight away
Powerness operates eight pickup locations in Germany: Mönchengladbach, Weinheim, Berlin, Hamburg, Tuningen, Riegelsberg, Munich and Westerkappeln. Those who choose self-collection benefit from cheaper prices compared to shipping and can often put the device into operation more quickly. Picking up is financially worthwhile, especially for larger complete sets.
Who is the TSUN DCU2000Lite suitable for?
- Balcony PV owners who want to store surplus and increase self-consumption;
- households that want to start small and later expand capacity in a modular manner;
- Attic apartments or gardens with partial shade thanks to dual MPPT;
- Customers who value easy retrofitting and app control.
Short conclusion
The TSUN DCU2000Lite is a well thought-out, modular storage solution for anyone who wants to use their balcony or small PV system more efficiently. Long-lasting battery cells, high PV input with dual MPPT and the option of self-collection at eight locations make the offer particularly attractive. Whether solo storage or a complete set with inverter and bifacial modules – Powerness offers suitable configurations for different needs.
