SolaX HV11550(H)V3 High Voltage Storage Battery Slave Pack 5.8 kWh LiFePO4
The Slave Pack HV11550(H)V3 is the expansion module of the SolaX T-BAT H 5.8 V3 high voltage storage system. It adds 5.8 kWh nominal to the tower but does not contain the BMS: it must always be paired with a Master Pack, which coordinates its charging, discharging and protections. It stacks onto the previous module, keeping the same footprint.
It uses the same cobalt-free LiFePO4 cells as the Master Pack, with 5.5 kWh usable at 95 % DoD and more than 6,000 declared cycles. The (H) version includes two-stage heating for operation down to -30 °C, while the IP66 rating allows floor or wall installation. A tower takes up to 5 modules; several towers in parallel make it possible to reach 34.6 kWh, and up to 69.1 kWh with dual battery port inverters.
