Note on indoor installation (according to Involtis): the battery storage systems meet the requirements of OIB Guideline 2 (fire protection, 2023 edition) – the passed safety test and proven thermal runaway protection are documented. This allows installation of up to 100 kWh total capacity in residential areas without a separate fire-protected room. Please coordinate the specific implementation with the locally responsible authorities – we will be happy to support you.
