Yes, modern EPEVER controllers support lithium batteries (LiFePO4). You can often select preset lithium modes (like LFP4S, LFP8S) or use the "User" mode to define custom parameters via the PC software, mobile app, or MT50 remote meter.
A flashing red fault light typically indicates a system error such as battery over-voltage, over-discharge, load short circuit, or controller overheating. Consult the "Troubleshooting" section of your specific user manual to identify the code associated with the flash pattern.
Connect the MT50 remote meter to the controller's RJ45 communication port using the supplied RS485 cable. The meter is powered directly by the controller ensuring easy real-time monitoring without external power sources.
