If libbi displays Code 159 / W08: Bat Volt High, this indicates that the incoming voltage to the batteries is higher than the safe operating threshold.
What does this mean?
The libbi continuously monitors battery voltage to ensure safe and efficient operation. When the voltage supplied to the batteries exceeds the allowed limit, the system triggers Code 159 / W08: Bat Volt High to protect the batteries and the inverter.
This warning helps prevent overcharging, which can reduce battery lifespan, cause overheating, or in extreme cases, damage the batteries. The inverter may temporarily stop charging or adjust its output until voltage levels return to a safe range.
Troubleshooting Steps
- Reboot the batteries and the libbi controller.
