Do You Need a Permit for Battery Storage Installation? in Polen
Usually yes. Home battery storage systems connect directly to the main electrical panel and often integrate with solar inverters, making an electrical permit mandatory in most jurisdictions. The permit ensures correct wiring, overcurrent protection, and fire-safety clearances. Unpermitted battery installations may void homeowner insurance and prevent utility interconnection approval.

Country-specific detail
In Poland, home battery storage systems (magazyny energii) connected to the grid require a notification (zgłoszenie) to the local starostwo when the installation alters the electrical przyłącze (connection). The operator sieci dystrybucyjnej (OSD — e.g. Tauron, Energa, PGE) must approve any change to the przyłącze capacity. Off-grid batteries without structural modifications typically require no building permit. Work must be performed by an electrician with uprawnienia SEP G1. Poland's prosument program encourages solar-plus-storage, and the application to OSD includes battery specifications.
