Note: High-voltage stacked battery for a high-voltage hybrid inverter, built from 5 HV9637S modules. Usable energy printed directly at 16.872 kWh (95% depth of discharge). Cycle life ≥6000 at 0.2C, 25°C, 95% DoD to 70% end-of-life. Maximum continuous charge and discharge power is 10.65 kW, which is 0.6C - so a full charge or discharge takes well over an hour. IP54. Up to 12 towers in parallel. Note the temperature window is tighter than the rest of the Dyness range: charging 0°C to 50°C and discharging -10°C to 50°C, against -20°C on the Tower Pro and the 48 V models - worth checking against winter lows if the battery is not in a heated space. The Tower Pro is the step up: 8000 cycles instead of 6000, 1C power instead of 0.6C, IP55 instead of IP54, and a built-in fire extinguisher the S3 datasheet does not list.
