FAQ

Q: Is this battery safe? Could there be a risk of fire or explosion?

A: Safety is our top design principle. This product uses the most stable lithium iron phosphate cells, whose thermal stability far exceeds that of other lithium batteries. This significantly reduces the risk of thermal runaway from the very beginning. At the same time, the battery's built-in intelligent BMS management system provides multiple hardware-level protections against overcharging, overdischarging, overcurrent, short circuit, and high temperature. The battery pack has also passed strict certifications such as CE/ROHS/MSDS/UN38.3 to ensure its safety and reliability during transportation and usage.

Q: How long can a 300Ah capacity support the operation of various household appliances in my home? A: The total energy is approximately 15.36 kWh (48V * 300Ah = 15.36kWh).

Here are some intuitive examples: Refrigerator: (about 150W) Can operate continuously for ~100 hours. LED lighting: (about 50W) Can stay on continuously for ~300 hours. Laptop: (about 60W) Can be used continuously for ~250 hours. 1-ton air conditioner: (about 1000W) Can operate continuously for ~15 hours. You can estimate the usage time of household appliances based on the formula "

Appliance power (W) × Usage time (h) = Energy consumption (Wh)".

Q: Is the installation complicated? What do I need to prepare? Is installation guidance provided? A: One of the major advantages of the wall-mounted design is its ease of installation. Preparations: You need to prepare a suitable installation wall (a load-bearing wall), necessary tools (screwdrivers, electric drills, etc.) and cables that meet the specifications. Installation steps: Fix the installation bracket -> Hang the battery -> Connect the DC output cable -> Connect the communication cable (if necessary) -> Power on. Installation guidance: We provide detailed installation instructions. If you encounter any problems during the installation process, our technical support team can offer online remote guidance.

Q: What specific protections does the BMS (Battery Management System) of the battery provide? A: Our intelligent BMS is the "brain and guardian" of the battery, offering comprehensive protection, including:Overcharge protection: Automatically cuts off when the voltage is fully charged to prevent damage to the cells. Overdischarge protection: Automatically shuts down when the voltage is too low to avoid deep discharge and battery failure. Overcurrent protection: Activates protection when the current exceeds the safety threshold to prevent overheating of the circuit. Short circuit protection: Instantly identifies and cuts off short circuit faults. Temperature protection: Automatically intervenes when the charging or discharging temperature exceeds the safe range (such as 0°C - 45°C for charging). Cell balancing: Ensures that the voltages of all cells are consistent, extending the overall battery life.

Q: What is the after-sales process if there is a problem with the battery? A: We have a clear after-sales process: Step 1: Contact our customer service by email or phone and describe the problem phenomenon. Step 2: Our technical support team will conduct a remote diagnosis and guide you on simple troubleshooting. Step 3: If it is confirmed to be a quality issue, we will arrange for a local repair point or factory return for repair based on your location. For non-human-caused problems within the warranty period (accidents and the like are usually not covered by the warranty), we will bear the repair costs.

Q: I Can See The Post That Your Company Shows The Warranty Is 5 Years, So No Matter What The Battery Pack Be Used For, All 5Years?

A: No Sir, Maybe You Know The Cycle Life Of Cell Is Not Only Depends On The Quality Itself , But Also Be Affected By The Discharge/Charge Rate The Actual Temperature. So It Is Unresponsibility At All If A Supplier Tell You The Cycle Life But No Talking About The Actual Usage. For Room Temperature 25℃ And 1c Discharge And 0.5c Charge, The Cycle Life Of The Battery Pack Can Exceed 8000 Cycles And Warranty 5 Years, Only Energy Storage Usage.

Q：How does your BMS look at battery data?
A：We can view the simple data of the battery string through the LCD screen connected with BMS, or view the detailed data of the battery string from the inverter after communicating with the inverter, or connect the computer through RS485 to USB adapter, and
view the upper computer software we provide installed on the computer. Q：Does your BMS have current balance?

A：yes,We have the current passive balance function, the passive balance function module is
integrated on the BMS board, do not need external balance device..

Q: Can this battery be compatible with my existing solar inverters (such as brands like Victron, Deye, Growatt, etc.)? A: Yes, the compatibility is very good. This battery supports CAN/RS485 communication protocols, and has preset communication protocols with mainstream inverters in the market (including but not limited to Victron, SMA, Deye, Growatt, Goodwe). Before purchasing, please inform us of the brand and model of your inverter, and we can assist you in confirming the compatibility and completing the matching settings before shipment.

4. Q: I need more features such as BT and LED screen,

Can I customize my battery pack?

A: Certainly. Just tell me what you need and our professional team of engineers will provide it for you An excellent solution that exceeds your expectations.

Q: How do I know whether you've shipped my order or not? A: Tracking No. will be offered as soon as your order be shipped out. Before that, our sales will be there to check the packing status, photo you the done order and let you know the forwarder picked it up.
