PV & BESS Assessor München — Technical Connection Requirements SWM Infrastruktur

München is our home base and the heart of our assessment practice. Whether villa PV in Bogenhausen, commercial storage in Messestadt Riem, or tenant electricity in Neuperlach — we know the TAB of SWM Infrastruktur inside and out from hundreds of projects. This deep local expertise is a key quality factor in our München assessments: we know what SWM looks for during grid connection inspections.

What are the special features of the München grid area?

SWM Infrastruktur operates the grid of the Bavarian state capital München with approximately 13,000 km of cable network. München offers PV subsidies through the FKG program — up to EUR 0.40/Wp. The technical minimum requirements are documented in detail online.

Which standards apply to PV systems in the München grid area?

Standard	Scope	Relevance for PV
VDE-AR-N 4100	Technical connection rules low voltage	Mandatory — meter location, service entrance, protection concept
VDE-AR-N 4105	Generation systems on LV grid	Mandatory for PV ≤ 135 kW
VDE-AR-N 4110	Technical connection rules medium voltage	Mandatory for PV > 135 kW
Supplementary TAB SWM Infrastruktur	Regional supplements	Grid operator-specific requirements
DIN VDE 0100-600	Initial verification of electrical installations	Mandatory inspection before commissioning

How does the PV system registration process work at SWM Infrastruktur?

1. Engage a certified electrical contractor: Only registered installers may submit the registration (exception: balcony power plants).
2. Grid compatibility assessment: For systems from approx. 30 kWp, SWM Infrastruktur checks the grid's absorption capacity.
3. Commissioning application: The installer submits data sheets, site plan, circuit diagram, and conformity certificates.
4. Prepare meter location: Must comply with VDE-AR-N 4100 and the supplementary TAB.
5. Installation and initial verification: Testing per DIN VDE 0100-600 by the electrical contractor.
6. Meter installation and commissioning: SWM Infrastruktur installs the bidirectional meter. MaStR registration is mandatory.

What are the requirements for the meter location?

Requirement	Specification
Meter type	eHZ in three-point mounting system
Surge protection	Type 1+2 combined arrester (mandatory for new systems)
SLS switch	Selective line protection switch upstream of the meter
Space reserve	Min. 1 slot for smart meter gateway
Equipotential bonding	Connection to main earthing busbar

How are balcony power plants registered with SWM Infrastruktur?

Balcony power plants up to 800 W can be registered through a simplified process. München subsidizes plug-in solar devices through the FKG program at EUR 0.40/Wp (max. EUR 320).

Which transmission system operator is responsible in München?

München is located in the TenneT control area. The responsible transmission system operator (TSO) is TenneT TSO GmbH. TenneT is responsible for system stability in the extra-high voltage grid (220/380 kV) and coordinates the feed-in of renewable energy at the transmission grid level. At the regional distribution grid level, Bayernwerk Netz is also an important player.

Level	Operator	Voltage Level	Relevance for PV/BESS
Transmission grid	TenneT	220-380 kV	System stability, EEG feed-in
Distribution grid	SWM Infrastruktur	0.4-20 kV	TAB, grid connection, meter location
Customer system	System operator	0.4 kV (LV)	PV array, BESS, inverter

What are typical challenges for PV and BESS in München?

München has specific regional characteristics as a location for PV and BESS projects that must be considered during planning and assessment:

High Commercial Roof Density in the Urban Area

München has one of the highest commercial roof densities in Germany. Over 60% of commercial flat roofs are fundamentally suitable for PV systems, yet structural limitations in existing buildings frequently require assessments on load-bearing capacity and module selection.

Grid Bottlenecks in the Inner-City Network

The low-voltage grid in München's inner city reaches capacity limits with high PV feed-in density. Grid compatibility assessments by SWM Infrastruktur regularly lead to feed-in limitations or the requirement for reactive power control per VDE-AR-N 4105.

Fire Protection for Listed Buildings

Strict heritage protection regulations apply in München's inner-city districts Altstadt-Lehel and Maxvorstadt. PV installations require coordination with the Bavarian State Office for Heritage Protection and extended fire protection concepts.

Storage Integration in Underground Garages and Basements

BESS installations in München residential complexes are increasingly planned for underground garages. This requires specialized fire protection assessments, ventilation concepts per DIN EN 62619, and coordination with the München Fire Department.

When is an expert assessment advisable?

Occasion	Our Service
Acceptance assessment	TAB conformity check, defect report
Dispute with grid operator	Independent technical evaluation
Systems from 30 kWp / medium voltage	Supervision, grid compatibility assessment
Defect assessment	DIN VDE 0100-600, thermography, EL
Capacity bottleneck	Grid analysis, alternative concepts
