ᐅ Install the inverter in the garage next to the utility room.

Good morning everyone!
I am currently planning to install a somewhat larger photovoltaic system on my house (location NRW).
Since the utility room is already quite full and, above all, well “heated” due to the washing machine and dryer, the water heater, network equipment, etc., and because additional wall space is limited, the plan was to mount the inverters (one for full feed-in and one for surplus feed-in) in the garage directly adjacent to the utility room.
The heat generated by the inverters would not be noticeable in the garage during summer and would not cause any issues in winter.
There is already a sub-distribution panel in the garage, where the 5 x 16 mm² (about 5 x 0.63 inch²) supply cable for the garage’s electrical system is connected.
The cable run from the meter cabinet to the inverters is about 3–4 m (10–13 feet), so pulling an additional cable for the full feed-in inverter would not be a problem.
Now my electrician told me that he sees a problem with installing the inverters in the garage.
Garages are fundamentally intended for parking cars, and in his opinion, only a wallbox charger is allowed to be installed there—nothing more.
I could not find anything about this in the VDE regulations. The only thing I knew about garage usage came from building law, but that should not be the electrician’s concern...
Furthermore, I have often read that energy storage systems are sometimes installed in garages due to their potential fire load. Even though this is not currently planned here, that would also contradict the intended use of the garage.
Do you have any further information on how to assess the electrician’s position?

The Wi-Fi is actually only used for your app on the phone and to configure the inverter. So, in addition to the power cable to the distribution board, always run a CAT7 network cable.
Basically, it is advisable to always place the battery storage and inverter outside the main house. In my case, everything is installed in a separate building in the technical room. That gives me peace of mind.
