Battery wear in VPPs

Home batteries wear with cycles and calendar age. VPP participation adds cycles. Three things contain that wear:

• Throughput warranties that cap kWh-over-lifetime, not just cycles.
• Minimum state-of-charge floors to protect longevity and backup reserve.
• Thermal management: placement and ventilation affect calendar wear.

Ask for the warranty's exact throughput limit and how VPP cycles are counted under it. The installer can configure SOC floors and charge windows so backup reserve and cycle life are both respected.
