Warranty & service
| conditions | Limited Warranty Europe-EN V1.2: the product will 'retain sixty per cent (60%) of its Usable Energy for ten (10) years' or reach the minimum throughput, 'whichever comes first'. Minimum throughput for this model: 42.69 MWh (usable energy 13.8 kWh). Warranty is void outside 'temperatures of greater than 50°C or less than -10°C', if the product is 'not being installed within one (1) month from Warranty Start Date', if the product is 'not being operated for any period of 6 months or more', or if it is not operated with a 'BYD certified inverter' from the Compatible Inverter List. |
