9.2  FOX-ESS LV5200 Solar Battery Troubleshooting

When the red/ green LED on the panel is flashing or normally on, it does not mean that the LV5200 is abnormal, it may be just an alarm or protection. Please check the ‘LED status indicators’ in chapter 7 for the detailed faulty definition before any trouble-shooting steps. In general, the alarm indication is normal without manual intervention. When the alarm triggering state is removed, LV5200 will automatically return to normal use.

– Problem determination based on the following points

  1. Whether the green light on the power switch is on;
  2.  Whether the buzzer in BMS is on;
  3. Whether the battery system can be communicated with inverter;
  4. Whether the battery can be output voltage or not FOX-ESS LV5200 Solar Battery.

– Preliminary determination steps

  1. Battery system cannot work, when DC switch on and POWER on, the LED doesn’t light up or flash, please consider contact the local distributor.
  2. The LED display of BMS is normal, but it cannot charge and discharge. Observe the display screen of inverter and there is no SOC. Please check whether the RS485 communication between BMS to inverter is well connected. If the connection is good, please replace a RS485 communication cable. If the SOC is still not visible on the inverter display screen, please contact the local distributor FOX-ESS LV5200 Solar Battery.
  3. After the battery system is powered on, if you can see the alarm information on the LED and inverter display screen at the same time, please contact the local distributor.
