Balcony battery storage unit catches fire in family home in Neuenhaus

What happened

A balcony battery energy storage system caught fire in a residential home in Neuenhaus, Lower Saxony, on 25 March 2025. A neighbour noticed smoke and alerted emergency services, who brought the fire under control within two hours. The house was unoccupied at the time. The battery, a Zendure 2.4 kWh lithium iron phosphate unit paired with a 1.78 kW balcony solar system, had reportedly been activated only two weeks before the fire.

The blaze damaged the home's heating and hot water systems and caused extensive damage to the utility room where the battery was installed. The unit was located in an annex whose roof structure required inspection afterwards. The rest of the house remained habitable, though the occupants temporarily relocated. The exact cause of the fire had not been established at the time of reporting, and an investigation was under way.

Contributing factors

The cause of the fire was not established at the time of reporting. The battery had only been in operation for around two weeks prior to the incident.

Lessons learned

1. A new Zendure balcony battery should be monitored closely in the first weeks after activation.
2. Battery storage in an enclosed utility room without fire separation can damage heating systems.
3. Early detection by a neighbour and rapid response limited damage to one annex.
