WARRANTY

The warranty shall not cover the defects caused by normal wear and tear, inadequate maintenance, handling, storage faulty repair, modifications to the battery or pack by a third party other than Felicity, failure to observe the product specification provided herein or improper use or installation, including but not limited to the following.

• Damage during transport or storage.
• Incorrect Installation of battery into pack or maintenance.
• Use of battery pr pack in inappropriate environment.
• Improper, inadequate, or incorrect charge, discharge or production circuit other than stipulated herein.
• Incorrect use or inappropriate use.
• Insufficient ventilation.
• Ignoring applicable safety warnings and instructions.
• Altering or attempted repairs y unauthorized personnel.
• In case of force majeure (ex: lightning, storm, flood, fire, earthquake, etc.).
• There are no warranties-implied or express-other than those stipulated herein. Felicity shall not be liable for any consequential or indirect damages arising or in connection with the product specification, battery or pack.

TROUBLESHOOTING AND MAINTENANCE

Maintenance

1. Regularly check whether the service environment of the battery meets the requirements, and the installation position should be far away from the heat source.
2. In case of one of the following situations, it needs to be charged in time:- The battery is often under charged;
   • The battery has been out of use or stored for more than 3 months.
3. Regularly check whether the battery and its supporting terminals, connecting cables and indicator lights are normal.

Troubleshooting
When the red / green LED on the panel is flashing or normally on, it does not mean that the Battery system is abnormal, it may be just an alarm or protection. Please check the ‘LED fault message’ 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, Battery system will automatically return to normal use.

Problem determination based on the following points

• Whether the red light on the BCU600050 is on;
• Whether the battery can be output voltage or not.
• Whether the battery system can be communicated with inverter;

Preliminary determination steps
LiFePO4 Battery System for HouseholdsBattery system cannot work, when DC switch on and POWER on, the LED doesn’t light up or flash, please consider contact the local distributor.

• The LED display of BCU600050 is normal, but it cannot charge and discharge. Observe the display screen of inverter and there is no SOC. Please check whether the CAN communication between BCU600050 to inverter is well connected. If the connection is good, please replace a CAN communication cable. If the SOC is still not visible on the inverter display screen, please contact the local distributor.
• 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.
