WEESSZugspitze Pro
All-in-one hybrid storage system for projects where battery storage must do more than simply store energy - it also needs to deliver backup, control and full system functionality.
Zugspitze Pro is not the storage unit itself, but rather the inverter module for setups with higher PV output, more flexible string configuration and integrated battery connection.
Zugspitze Pro combines PV, storage and backup in a controllable inverter logic.
The benefits stem not only from the power rating, but also from the role of the inverter within the overall system.
What you can achieve with it
- With up to 27,000 W of PV input power and 3 MPP trackers, the PV side can be configured more flexibly and adapted to different project requirements.
- Zugspitze Pro is designed for storage applications and combines PV and battery systems in a clear hybrid inverter structure.
- A switchover time of less than 10 ms is available for suitable emergency power and backup scenarios.
- Zugspitze Pro excels where inverters are not intended to operate in isolation, but rather as a central component within a larger energy system.
Up to 27,000 W PV input power, 3 MPP trackers and flexible string configuration provide scope for more complex PV layouts.
Maximum efficiency is 98.0%, whilst European efficiency stands at 97.3%. This ensures that conversion efficiency remains high even during operation.
With an IP65 protection rating, an operating temperature range of -25 °C to +60 °C and operation at altitudes of up to 4,000 m, Zugspitze Pro is designed for demanding operating conditions.
The battery voltage range of 180–600 V and two battery inputs provide the basis for suitable storage connections in the project.

Backup in three distinct supply levels
Device backup
For critical loads such as routers, lighting, cooling or selected socket circuits.
Room backup
For specific areas such as technical rooms, offices, basements or other clearly defined functional zones.
Home backup
For more comprehensive supply scenarios with manual or automatic switching.
Hybrid inverter as a system control centre.
PV, battery, AC output and communication are combined in a single device.
Example scenario: hybrid operation in a building
On the PV side
Up to 27,000 W PV input power, 1,000 V maximum voltage and 3 MPP trackers.
Battery-side
LFP, 180–600 V battery voltage range and 25 A + 25 A charge/discharge current.
Communication
RS485, CAN, Wi-Fi / Ethernet via Smart Dongle.
Remote control
Remote control via potential-free contacts (dry nodes).
Zugspitze Pro functions as an inverter module. When set up correctly, it becomes more than just a single device.
When PV, inverters, storage and distribution need to be considered as a whole, Zugspitze Pro can be combined with the Zugspitze battery and the WEESS PowerTower.

When Zugspitze Pro is particularly well suited
Large-scale PV and storage projects
- When higher PV output, flexible design and storage integration need to be combined in a hybrid inverter.
Projects with flexible MPPT and string structures
- When multiple trackers and a more flexible PV design are crucial to the project.
Structured setups with storage and distribution
- If Zugspitze Pro is not to be used as a standalone unit, but rather as an inverter module within a larger WEESS solution.
