Update 2026: Battery subsystem setup mandatory
Last modified:
Note
By the end of March 2026, it will become mandatory to activate the Battery monitoring module and set up a battery subsystem if you want to monitor battery data and your system’s battery capacity exceeds 30 kWh.
What is changing and when?
meteocontrol will support battery monitoring and alarm functionalities for systems with a battery capacity >30 kWh only if the Battery monitoring module is activated and a battery subsystem is fully set up.
meteocontrol will no longer support battery monitoring for systems with a battery capacity >30 kWh if the Battery monitoring module is not activated and a battery subsystem is not set up. As long as this did not happen, the battery devices will only be visible in your system, but without monitoring or alarm capabilities.
meteocontrol will continue battery monitoring and alarm functionalities for systems with a battery capacity <30 kWh, even if no Battery monitoring module is activated and no battery subsystem is set up. This way, you can still access legacy data if you add a battery subsystem later.
The changes will take effect by the end of Q1 2026, which is the end of March 2026.
System’s battery capacity
The capacity limit applies to the total combined capacity of all batteries in your system. For example, if your system has three batteries with a capacity of 30 kWh each, you must activate the Battery monitoring module and set up a battery subsystem as the combined capacity is 90 kWh and therefore exceeds the 30 kWh limit.
Why is this happening?
meteocontrol strives to build a monitoring and analytics platform that reflects the flexibility and diversity of battery technology, system design, and market requirements. A fully set up battery subsystem is the only way to allow VCOM to differentiate between PV and battery assets. And this is required to guarantee consistent and reliable data, charts, alarms, and evaluations across different asset types and thus a future-proof professional battery monitoring.
What you must do now?
Depending on your individual system, these are the next steps you must take:
A) You already set up a battery subsystem
There is nothing else you must do. Your battery data import, alarm, and monitoring capabilities will remain the same.
B) You have not set up a battery subsystem yet, and your system’s battery capacities are lower than 30 kWh
There is nothing else you must do. Your battery data import and monitoring capabilities will remain the same.
C) You have not set up a battery subsystem yet, and your system’s battery capacities exceed 30 kWh
Activate the Battery monitoring module and add a battery subsystem to your system to specify the battery inverters and the installed capacity of your battery. See Add a battery as subsystem.
Note
VCOM Battery monitoring module requires a fee-based license. Trials are available on request. Please contact your meteocontrol sales agent or our sales team at sales@meteocontrol.com.
If your contract is newer than July 2024, you can activate the VCOM Battery monitoring module on your own. See Activate the module Battery monitoring. If you encounter technical problems, please contact Support.
D) You have a hybrid inverter or a battery for uninterruptible power supply (UPS)
Further information on licensing and step-by-step instructions for setting up a battery subsystem for hybrid inverters or for UPSs will be added to this Help Center in Q4 2025.
