Update 2026: Battery subsystem setup mandatory

Last modified:


Note

At the end of March 2026, it became mandatory to activate the Battery monitoring module and set up a battery subsystem if you want to monitor battery data.

For uninterruptible power supplies (UPS), see details below.

What changed and when?

  • meteocontrol supports battery monitoring and alarm functionalities for systems with a battery only if the Battery monitoring module is activated, and a battery subsystem is fully set up.

  • meteocontrol no longer supports battery monitoring for systems with a battery 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 is only visible in your system, but without monitoring or alarm capabilities.

  • The changes took effect at the end of Q1 2026, which is the end of March 2026.

What if I only have an uninterruptible power supply (UPS) in my system?

UPS devices are treated as regular batteries and, therefore, must be set up as battery subsystems. But to allow small UPS devices to be monitored free of charge, we introduced a < 30 kWh battery capacity limit as of 13 Jan, 2026. This means that if your UPS capacity is lower than 30 kWh, setting up a battery subsystem does not incur additional costs anymore, as you do not have to activate the Battery monitoring module to be able to do that.

The capacity limit applies to the total combined capacity of all UPSs in your system.

Why did this happen?

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

Depending on your individual system, these are the steps you must take:

A) You already set up a battery subsystem.

If you already set up a battery subsystem before the end of March 2026, there is nothing else you must do. Your battery data import, alarm, and monitoring capabilities remain the same.

B) You have not set up a battery subsystem yet.

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 subsystem.

Note

C) You only have an uninterruptible power supply (UPS).

You must set up the UPS (< 30 kWh) as battery subsystem to ensure monitoring from Q2 2026 onwards. See Add a battery subsystem. This will not incur additional costs.

D) You have a hybrid inverter.

Activate the Battery monitoring module and add a Hybrid subsystem (PV + Battery) to your system to specify the battery capacity and the PV inputs. See Add a hybrid subsystem.
