Frequently asked questions

Answer:
Look for:
• Manufacturer traceability (QR code, serial number)
• Consistent cell voltage and internal resistance
• Date code less than 12 months old
• Testing via complete charge/discharge cycles
All our battery packs use Grade A, UN38.3 certified cells.

Answer:
Possible reasons:
• Improper charging (over-voltage/under-charging)
• Ambient temperatures exceeding 40°C, accelerating degradation
• Poor cell quality (non-Grade A)
Our batteries use certified Grade A cells and a smart BMS, ensuring ≥85% capacity retention after 3 years.

Answer:
• LiFePO4 (LFP): 4,000-7,000 cycles, more stable, safer, lower energy density
• NMC/NCA: 2,000-3,000 cycles, higher energy density, but poorer thermal stability
For stationary energy storage systems (ESS, off-grid), LiFePO4 is the recommended choice due to its safety and cycle life.

Answer:
Typical lifespan for LiFePO4 (LFP) batteries:
• Over 6,000 cycles at 80% Depth of Discharge (DoD)
• 10-15 years service life under normal off-grid or hybrid use conditions
Proper battery management and ambient temperature control (15-35°C) can significantly extend battery life.

Answer:
• A typical 1.5 HP air conditioner consumes about 1.2 kW
• 24-hour consumption = approx. 28.8 kWh/day
• You need approx. 30 kWh of usable capacity, or approx. 38 kWh total capacity (assuming 80% DoD for LiFePO4 batteries)
Tip: Pair with solar + an MPPT charge controller for sustainable operation.

Answer:
Please check the following:
• Communication cable (use shielded twisted pair where possible)
• Correct port (some inverters have dual CAN/RS485 interfaces)
• Battery address set to 1
• Ensure the protocol matches the inverter firmware
If the problem persists, please contact our support team for remote troubleshooting.

Answer:
Our batteries are compatible with most major brands, including:
• Growatt (SPF, MOD, MIN series)
• GoodWe, Luxpower, SMA, etc.
We provide wiring diagrams and pre-set communication settings for easy plug-and-play installation.

Answer:
Common reasons include:
• Communication protocol mismatch (RS485 vs. CAN)
• Inverter not on the battery's whitelist
• Wiring errors or reversed polarity
• Outdated firmware version on either side
Tip: Always confirm communication settings before connecting. We can provide a free inverter compatibility guide upon request.
