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 one circuit directly supply the
load, another circuit to charge Fe lithium load, another circuit to charge Fe lithium
pack. When grid power on,pack. When grid power on,
the system supply the loads and charging inside Fe lithium batteries; When grid power failure, Fethe 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 aslithium inside system supply DC power to the load, to ensure uninterrupted power supply as
power system.power system.
