Sungrow baterija sbp4k8 4.8kwh 48v

The batteries have a cycle life of 4,000 cycles, which works out to just over 1x cycle per day over the products 10-year warranty period. By the end of the 10 years, or the end of the 4,000 cycles, the battery is warrantied to retain at least 70% of its original capacity – which means it should still be able to store at least 3.15kWh of usable energy when either of these milestones is reached. The warranty does not specify – as some others do – exactly how the batterys storage capacity will degrade over time (e.g. how much you can expect at 5 years / 2,000 cycles), nor does it mention any energy throughput figures.
