Your goal is to turn this into a complete solar-powered EPS schematic.
  • I’ve prepared a plan covering:
    1. Solar inputs, inhibit, and protection
    2. Battery, BMS, charger, and main power bus
    3. Rail generation, switching, and monitoring
    4. Control/telemetry and external connector integration
The plan is ready to execute. Click Start on the plan bar to build it, or tell me what you want changed first.
Use STM32L431 instead
Keep exact net names
Add review after build
