WEESSZugspitze
All-in-One Hybrid-Speichersystem für Projekte, in denen ein Batteriespeicher nicht nur Energie puffert, sondern Backup, Steuerung und Systemfähigkeit liefern muss.

Zugspitze is not just a battery storage system, but an all-in-one system for PV, consumption and backup. This creates a compact product concept that not only stores energy flows, but actively manages them.
More than just storage: Zugspitze manages, secures and organises energy flows.
The value of the Zugspitze lies not only in its capacity, but also in its role within the overall system.
What you can achieve with it
The hybrid inverter is part of the system. This means that the storage unit and the inverter are not connected separately, but work together as a compact unit.
Lithium iron phosphate offers high safety, a long service life and stable performance in day-to-day operation.
Zugspitze can be integrated into various backup concepts and thus support security of supply within the appropriate framework.
The system integrates storage, PV and consumption within a controllable structure, thereby laying the foundation for transparent operational logic.

Backup in three distinct supply levels
Not every project requires the same level of supply security. Zugspitze can be integrated into various backup scenarios.
Device backup
For critical loads such as routers, lighting, cooling or selected circuits.
Room backup
For specific areas such as technical rooms, offices or individual functional zones.
Advanced backup
For more comprehensive supply scenarios with manual or automatic switching.
Storage as a control centre.
HEMS-ready: generation, consumption and storage operations intelligently coordinated.
Example scenario: Optimal operation

Energy distribution at this moment
HEMS decision: Surplus PV energy is fed entirely into the Zugspitze. No feed-in to the grid – maximum self-consumption.
Affordable charging
Make targeted use of tariff and pricing windows where the project is designed to do so.
Smart charging
Use storage strategically when demand rises or to use energy more efficiently.
Coordinate heat pump
Integrating consumers into the energy system with clear priorities.
Optimise self-consumption
Coordinate PV generation and storage usage so that more energy remains within your own system.
Zugspitze + PowerTower
When storage and distribution need to be considered together, Zugspitze can be combined with the WEESS PowerTower. This creates a setup in which generation, storage and structured energy distribution mesh seamlessly.

When Zugspitze is particularly well suited
Zugspitze is the right choice when a storage facility is not to be viewed in isolation, but rather as a key component in the energy flow.
Private PV and storage projects
- When self-consumption, backup and a compact system architecture are the key priorities.
Projects requiring intelligent control
- When storage, generation and consumption are to interact within an active energy flow logic.
Structured setups with system integration
- If Zugspitze is to be used not only as a storage facility but also as an integrable component within a larger WEESS solution.

Frequently asked questions
Frequently asked questions about WEESS Zugspitze
The WEESS Zugspitze is an all-in-one energy storage system featuring an integrated hybrid inverter, battery modules and intelligent control. It combines PV generation, storage operation and consumption in a compact system.
The Zugspitze is available in three versions: 10.24 kWh, 15.36 kWh and 20.48 kWh. The appropriate configuration depends on PV output, consumption, the desired level of backup and the goal of optimising self-consumption.
The Zugspitze supports up to 13,000 W of PV input power. The system operates with 2 MPP trackers and 3 strings.
Yes. Multiple backup scenarios – from individual devices to advanced power supply solutions. The switchover time is less than 20 ms.
Yes. The Zugspitze is part of a smart energy management system, including an SG-Ready heat pump, a wallbox and dynamic tariffs.
