Special Attention bullet on page 1 (section 1.4): 'Due to the built-in protection board of the lithium battery pack is with over-discharge protection function, it is strongly recommended to stop using the load when the battery pack is over-discharged. The battery pack cannot be repeatedly activated for discharge. Or the battery may be failed to be activated by the AC or PV activation cable (it requires a special charging activation method), so cannot be charged.' This is a documented advisory rather than a numbered C-code, but it describes a distinct unrecoverable condition reachable through C02 / C04.
Repeated activation attempts on a deeply over-discharged pack, exhausting the BMS's normal wake-up path so that even AC or PV activation no longer works.
Stop using the load as soon as low power is indicated and recharge the battery from mains or solar as soon as possible. if the pack cannot be activated by the AC or PV activation cable, contact the supplier - a special charging activation method is required.
