The request
“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.”
Then tryChange the battery to 48 V.Add a battery voltage monitor.
What is in this drawing
Read the decisions behind it.
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.
