Q
Is this battery safe? Could there be a risk of fire or explosion?
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?
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?
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) provide?
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.
- Short circuit protection: Instantly identifies and cuts off short circuit faults.
- Temperature protection: Automatically intervenes when 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
Can this battery be compatible with my existing solar inverters (such as brands like Victron, Deye, Growatt, etc.)?
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.
Q
Can I customize my battery pack (e.g. Bluetooth and LED screen)?
Certainly. Just tell us what you need and our professional team of engineers will provide an excellent solution that exceeds your expectations.
