Even though LiFePO₄ is one of the safest lithium chemistries, proper safety maintenance ensures risk-free operation and compliance with industry standards.
1. Keep the Battery Area Clean and Free of Contaminants
Dust accumulation affects heat dissipation and may cause insulation failure.
Tips
✔ Clean the area monthly
✔ Avoid storing liquids or chemicals near the battery
✔ Keep cables elevated from wet floors
✔ Ensure there is no insect or rodent activity
2. Confirm All Protection Settings Regularly
Your ESS must have properly configured protection:
- Overcharge protection
- Over-discharge protection
- Overcurrent protection
- Short-circuit protection
- High/low temperature protection
- Cell balancing threshold
Daily/Weekly Checks
✔ Verify BMS protection status on the app
✔ Review inverter safety logs
✔ Confirm breaker ratings match system capacity
✔ Ensure fuses are not discolored
3. Avoid Using Mixed Batteries
Never mix:
- Old and new batteries
- Different brands
- Different cell capacities
- Different SOH values
This causes internal imbalance and shortens lifespan.
4. Ensure Proper Grounding
Proper grounding prevents:
- Electrical noise
- BMS communication errors
- Damage from surge and lightning
- Unstable voltage
Always use thick, corrosion-resistant ground wires.
5. Use Only Certified Accessories
Cheap components often cause fires, voltage drops, or overheating.
Ensure all parts are:
✔ CE / UL / TUV certified
✔ Flame-retardant rated
✔ Correctly sized for current
✔ Compatible with LiFePO₄ chemistry
