Learn how to troubleshoot and fix the BYD Premium HVS SOC stuck at 0 percent issue effectively.
The SOC may be stuck due to a software glitch, sensor failure, or battery management system issues.
Resetting the BMS typically involves disconnecting the battery from power for a few minutes and reconnecting it.
The SOC being stuck at 0 percent often indicates a fault in the battery management system (BMS) or communication issues between the battery and the inverter. The BMS is responsible for monitoring the voltage and current of each cell, ensuring they operate within safe limits. If the BMS cannot accurately assess the SOC due to internal faults or external communication failures, it will report 0 percent. This may also be triggered by insufficient voltage from the solar array, which prevents the battery from receiving adequate charge.
The BYD Premium HVS displays a state of charge (SOC) stuck at 0 percent on the monitoring app. The LED indicators on the battery unit may blink erratically or remain steady, indicating a fault. Additionally, the inverter may show a warning message or fault code, and energy production from the solar array may drop significantly, leading to an inability to charge the battery.
Always consult with a licensed electrician or certified solar installer when performing diagnostics or repairs to ensure safety and compliance with local electrical codes.
