NPFC battery working principle: NPFC battery working principle:
DC power input charge and discharge management unit after filter, DC divided two circuits, DC power input charge and discharge management unit after filter, DC divided two circuits,
one circuit directly supply the load, another circuit to charge Fe lithium one circuit directly supply the
the system supply the loads and charging inside Fe lithium batteries; When grid power failure, Fe the system supply the loads and charging inside Fe lithium batteries; When grid power failure, Fe
lithium inside system supply DC power to the load, to ensure uninterrupted power supply as lithium inside system supply DC power to the load, to ensure uninterrupted power supply as
