Dyness 11.52kWh Lithium-ion Battery 288V (Tower-Pro-TP11)

Note: High-voltage stacked battery rather than a 48 V unit, so it pairs with a high-voltage hybrid inverter, not the usual low-voltage ones. Built from 3 HV9640 modules (3.84 kWh, 40 Ah, 96 V, 40.5 kg each) on a base, cable-free - the modules stack and connect without wiring. Usable energy is printed directly at 10.944 kWh (95% depth of discharge). Cycle life ≥8000 at 0.2C, 25°C, 95% DoD to 70% end-of-life, with a 10-year warranty. Maximum continuous charge and discharge power is 11.52 kW - a full 1C, so the whole pack can be emptied in an hour, which is unusually strong. IP55 and naturally cooled, with a built-in aerosol fire extinguisher and WiFi with app. Up to 12 Tower Pro clusters in parallel. Discharge is rated to -20°C but charge stops at 0°C unless the optional low-temperature pack is fitted. Against the cheaper Tower S3: the Pro has 8000 cycles to the S3's 6000, 1C power to the S3's 0.6C, and IP55 to IP54 - it is the premium line of the two.
