Bess Battery LiFePO4 10.24 kWh 51.2V

10.24kWh in a single 48V-system battery. The Bess 10.24kWh lithium battery is a 51.2V LiFePO4 storage module built to the mainstream 16-cell, 200Ah configuration that has become the de facto standard for residential and light commercial energy storage. At 10.24kWh of total capacity, a single Bess unit delivers roughly twice the storage of a typical 5kWh residential battery — useful for households wanting longer evening runtime, small businesses with bigger daily energy footprints, or installations where a single larger battery is preferable to paralleling smaller units. The 51.2V nominal voltage comes from the standard 16-cell LiFePO4 series configuration (16 × 3.2V cells), which is the same architecture used across the dominant 48V-system battery brands on the South African market. This standardisation means the Bess fits naturally into the 48V hybrid inverter ecosystem that most local installers already work with — though specific inverter compatibility, firmware versions, and communication protocols should always be confirmed with your installer before purchase. LiFePO4 (Lithium Iron Phosphate) chemistry is the safety-and-longevity choice for residential energy storage. Compared to other lithium chemistries, LiFePO4 is thermally more stable, less prone to thermal runaway, and typically delivers a longer cycle life — characteristics that matter for a battery expected to operate for years through daily charge/discharge cycles in South African ambient conditions. Beyond the verified headline specs, detailed Bess-specific specifications — including exact continuous charge/discharge current, parallel capacity, communication protocol (CAN bus, RS485 or RS232), IP rating, mounting format, physical dimensions, weight, and the official inverter compatibility list — should be confirmed directly with the supplier before purchase, especially if you need to match against an existing system or compare with other 10.24kWh options. Specifications at a glance: Total capacity: 10.24 kWh Nominal voltage: 51.2V (16-cell LiFePO4 configuration) Implied capacity: 200Ah (51.2V × 200Ah = 10.24 kWh) Cell chemistry: LiFePO4 (Lithium Iron Phosphate) System type: 48V-system battery (paired with 48V hybrid inverters) Key Features 10.24kWh of usable LiFePO4 storage — meaningful single-unit capacity for residential and small commercial setups 51.2V nominal voltage — built to the mainstream 16-cell LFP standard used across the SA energy storage market LiFePO4 chemistry — chosen for thermal stability and long cycle life relative to other lithium chemistries 48V-system compatible — pairs with mainstream hybrid inverters (specific compatibility list to be confirmed with the supplier) Battery Management System — integrated cell-level protection (over-charge, over-discharge, over-current, over-temperature) is standard at this configuration; confirm specific BMS feature set with the supplier Twice the capacity of a typical 5kWh residential battery — reduces the number of units required for higher-storage installations
