Discover why your Solis hybrid inverter isn't discharging the BYD battery at night and how to fix it.
The inverter may not discharge due to low battery voltage, incorrect settings, or a fault in the system.
You can check the battery status through the inverter's display or monitoring app to ensure it's functioning properly.
The inverter's primary role is to convert DC power from the solar array and battery into AC power for household use. When the inverter is not discharging the BYD battery at night, it may be due to programmed settings that prevent discharge below a certain battery state of charge (SOC). The inverter employs a battery management system to monitor various parameters, including voltage, temperature, and SOC. If these parameters fall outside predefined limits, the inverter may inhibit discharge to protect the battery's integrity. Communication protocols between the inverter and the battery must also be functional; any disruption can lead to incorrect operational commands.
Homeowners may notice that the Solis hybrid inverter's LED indicators show a steady green light, indicating operation, but there is no power being discharged from the BYD battery during nighttime. The monitoring app may display a continuous state of charge without any discharge activity, or it may indicate an abnormal status for the battery. Additionally, the energy consumption during the night does not reflect any utilization of stored energy from the battery.
Always consult a licensed electrician or certified solar installer for any electrical troubleshooting or repairs to ensure compliance with safety standards and local codes.
To avoid this issue in the future, regularly maintain the inverter and battery system by checking firmware updates, ensuring secure connections, and monitoring battery performance. Establish a routine inspection schedule to assess the SOC and load demands, and configure the inverter settings appropriately to match the battery specifications.
