Pricing in the residential battery segment was mixed in July.
- High-voltage premium brands: €316.0/kWh (-3 percent vs the previous month)
- High-voltage performance brands: €165.3/kWh (-2 percent vs the previous month)
- Low-voltage brands: €108.6/kWh (+10 percent vs the previous month)
High-voltage premium systems continue to trade at roughly two and a half times the level of low-voltage products, a ratio that has been remarkably stable through the year. Performance-tier high-voltage brands sit between the two and remain the fastest-moving part of the residential market.

Commercial and industrial segment, 20–120 kWh
20–60 kWh: €219.6/kWh (-2 percent vs the previous month)
60–120 kWh: €193.2/kWh (-1 percent vs the previous month)
Commercial storage pricing eased in both size bands. The larger 60–120 kWh class continues to price roughly a quarter below the smaller systems per kWh. That gap has held steady all year, and the economics of stepping up a size class remain intact.
