需求
“Draw an off-grid solar e-bike charging circuit with an 18 V PV panel, 10 A fuse, PV disconnect, diode, MPPT charge controller, 15 A battery fuse, 36 V battery, output disconnect and e-bike charger port.”
接著試試Change the battery to 48 V.Add a battery voltage monitor.
這張圖裡有什麼
看懂背後的決策。
01
Add series diode to prevent battery discharge into the panel at night.
02
Use MPPT charge controller between panel and battery for efficient 36V charging.
03
Include fused output switch to isolate the e-bike charger/load.
Reusable for portable solar charging stations, small off-grid EV battery maintenance, or any 12-48V solar-to-battery system with user disconnect.
