Battery wear in VPPs

Home batteries wear with cycles and calendar age. VPP participation can add cycles. The protection comes from:

• Throughput warranties (kWh over time).
• Minimum state-of-charge (to preserve longevity and backup).
• Thermal management (placement & ventilation matter).

Ask for the warranty's exact throughput limit, and where the VPP cycles will count. A good installer helps tune SOC floors and charge windows so comfort and longevity remain in balance.
