SMT-S16S1AM-SMTV1.1 is a BMS applied to energy storage system, which can support 16 series lithium iron phosphate batteries. This scheme adopts the special lithium battery management IC + MCU scheme, which can realize the basic protection function and accurately estimate and display the remaining capacity of the battery; BMS is equipped with RS485 / RS232 to communicate with the inverter, which can report the real-time data and status of the battery to the control module and interact with the inverter.
