1) What should I pay attention to when installing the LFW51200(51.2V 200Ah Wall-Mounted) battery?
a. Always disconnect the power before you start any wiring work. This is the most important step to prevent electric shock or fire.
b. Make sure to use insulated tools and wear protective gloves. Also, take off any rings, watches, or other metal jewelry you might be wearing.
c. Another thing to remember is to keep a safe distance—at least 0.5 meters—from any heat sources while you’re working.
d. When connecting the terminals, always attach the negative terminal (P-) first, and only then connect the positive terminal (P+).
e. Finally, once the installation is complete, don’t forget to cover all terminals with their insulation caps for long-term safety.
2) Can the 51.2V 200Ah wall-mounted battery be used in parallel?
Yes, up to 16 units can be connected in parallel. Follow these steps:
a. Ensure the voltage difference between batteries is <2V before connecting them.
b. Connect all positive terminals together and all negative terminals together. Series connection is prohibited.
c. Cascade communication cables: Connect the RS485A port of one battery to the RS485B port of the next.
d. Set the master and slave addresses via the DIP switches.
3) How do I switch the batterylanguage?
Press and hold the Enter button for three seconds to switch between Chinese and English.
4) What safety precautions must be followed?
a. Use only with compatible inverters.
b. Do not disassemble, puncture, short-circuit, or expose to fire/water.
c. Keep away from flammable materials and corrosive substances.
d. If swelling, leakage, or damage is observed, stop use immediately.
e. Only qualified personnel should perform maintenance or change parameters.
5) How should the 51.2V 200Ah Wall-Mounted battery be stored if not in use?
a. Store with a State of Charge (SOC) ≥ 50%.
b. Keep in a dry, cool place (temperature < 45°C).
c. For long-term storage, recharge at least once every six months.
6）How to set the communication protocol for my inverter?
On the screen:
a. From the main page, press NUM+ to enter the protocol switch interface.
b. Select the correct protocol (e.g., Pylontech, Growatt, Victron, SMA).
c. Long-press ENTER for 3 seconds until “SUCCESS” appears.
