Pricing in the residential battery segment was mixed in June, with the performance category pulling back sharply while premium systems moved higher.
- High-voltage premium brands: €280.8/kWh (+3% vs May)
- High-voltage performance brands: €150.5/kWh (–6% vs May)
- Low-voltage brands: €108.6/kWh (–1% vs May)
The high-voltage performance segment recorded its largest monthly decline of the year, extending the correction that began in May after April's sharp increase driven by Deye and Growatt pricing activity. Premium high-voltage systems, by contrast, edged back up in June, moving further away from April's cycle low. Low-voltage batteries saw only a marginal decline, continuing the gradual softening trend visible since March.

Commercial segment (20–120 kWh): offer volumes rebound in the smaller segment
Marketplace activity in the commercial and industrial storage segment picked up in June, particularly in the 20–30 kWh range, while average pricing in the 60–120 kWh category dropped sharply.
- 20–30 kWh systems: €232.4/kWh (–1% m/m)
- 60–120 kWh systems: €195.7/kWh (–14% m/m)
The number of active offers in the 20–30 kWh range rose to 84, up 8% month-on-month, reversing the gradual decline seen since February. Pricing in this segment remained broadly stable, easing only slightly compared with May.

The 60–120 kWh segment told a different story: while the number of active offers also increased slightly, to 26, average pricing fell sharply. The decline was driven mainly by the disappearance from the marketplace of the product with the second-highest unit price in this category, rather than by a broader repricing of the segment.
