Ideal Home Application Scenarios
1. Solar PV Self-Consumption
Stores excess energy generated by your rooftop solar panels during the day, for use in the evening or overnight - reduces your reliance on grid power and lowers electricity bills.
2. Emergency Backup Power
Acts as a reliable UPS for your home, powering essential appliances during grid outages - no more disrupted daily life.
3. Off-Grid Home Power
Combines with a solar inverter and PV array for a complete off-grid energy system - ideal for rural homes, cabins or properties with no grid access.
4. Peak Shaving (Time-of-Use Pricing)
Charges the battery during off-peak grid electricity hours and discharges during peak hours - maximizes savings on variable electricity tariffs.
5. Scalable Home Energy Systems
Start with 1 module (5.12kWh) for basic needs, then add up to 3 more modules for a 20.48kWh system - grow with your household's energy demand.
Simple Maintenance & Troubleshooting
The CBLV 5120-C is a low-maintenance battery system - follow these simple guidelines for long-term performance.
Routine Maintenance
- Maintenance Charging: Recharge the battery every 6 months (from shipment date); recharge immediately if SOC drops to 0%.
- Storage Preparation: If not in use, set SOC to 45%-55% and disconnect the battery output to prevent over-discharging.
- Environmental Check: Keep the battery in a cool, dry indoor space - avoid direct sunlight, heat sources and water spillage.
- Cleaning: Wipe the battery casing with a dry cloth or soft brush; do not use corrosive cleaning liquids.
- Regular Inspection: Check wiring and connections for looseness; monitor SOC and temperature for abnormal performance.

Storage & Handling Guidelines
Short-Term Home Storage (1-6 Months)
- Store in a clean, dry, ventilated indoor space (20°C-30°C)
- Maintain SOC at 45%-55%
- Keep away from heat sources, direct sunlight and corrosive materials
- Do not place heavy objects on the battery; do not store upside down
Long-Term Storage (6+ Months)
- Recharge the battery to 45%-55% every 3 months
- Disconnect all electrical connections (output, communication, grounding)
- Keep the storage area humidity below 75% RH
Safe Handling Rules
- Handle gently - avoid dropping, shaking or impact
- Wear insulating gloves when handling or wiring the battery
- Do not touch positive/negative terminals with metal objects (prevents short circuit)
- Keep out of reach of children and pets
Safety Precautions & Emergency Handling
Your safety is our top priority - follow these rules for safe operation, and know how to respond to rare emergency situations.
Basic Safety Rules
- Indoor Use Only: IP20 protection - do not use outdoors (no rain/snow/dust protection)
- No Open Flames: Keep the battery 3+ feet away from fire, candles, heaters and flammable materials
- Prevent Water Damage: Avoid water spillage/immersion - water damage causes electric shock/short circuit
- Static Protection: Discharge static electricity before touching the battery (e.g., touch a metal surface)
- Professional Service Only: Do not disassemble the battery - internal components are high-voltage; contact a qualified technician for repairs
Emergency Handling
Damaged/Deformed Battery Enclosure
Risk: Electrolyte leakage, internal short circuit, toxic gas release
Action: Evacuate the area, keep away from the battery, do not touch any part; contact your local fire department and battery supplier immediately
If Contact Occurs: Rinse skin/eyes with plenty of water (15 mins for eyes); seek medical attention right away
Battery Fire (Rare)
Action: DO NOT ATTEMPT TO EXTINGUISH - evacuate your home immediately and call the fire department
Note: If fire is from other sources (not the battery), use FM-200 or CO2 fire extinguisher before it spreads to the battery
Water Damage
Action: Turn off all power (if safe), keep away from the battery; do not reuse a submerged battery
Next Step: Contact the supplier for support/replacement
