Das Szenario
An 800 W rooftop solar array charges a 48 V 20 Ah Li-ion bank through an MPPT controller in an off-grid shed; the bank powers a 48 V to 54.6 V charger for a 750 W commuter e-bike battery.
Was diese Zeichnung zeigt
Die dahinterstehenden Entscheidungen verstehen.
01
Using an MPPT charge controller instead of direct PV-to-battery connection maximizes energy harvest
02
Placing a system switch and fuse between the battery bank and the e-bike charger isolates the load and protects wiring
03
Selecting a 48 V nominal e-bike battery and 54.6 V charger matches common 13S lithium-ion e-bike packs
Use this architecture for any small off-grid charging station where a stationary battery buffers solar energy for later charging of e-bike or similar 48 V lithium batteries.
