If your libbi displays Code 164 / W13: BAT Power Down, this indicates that the libbi's batteries do not contain sufficient power to discharge.
What this means?
The libbi relies on its batteries to supply backup power or to manage energy flow from solar PV. When the battery charge falls below a minimum threshold, the system triggers Code 164 / W13: BAT Power Down to protect the batteries from deep discharge, which could damage them and reduce their lifespan.
During this condition, the inverter may temporarily stop drawing power from the batteries and will wait until the batteries have been recharged to a safe level.
