Schematics (placeholder)

Placeholder file: schematics/solar_v1.pdf

Suggested schematic sections (create and export as PDF/SVG):

  1. PV array configuration (series/parallel) → PV fuse → SPD → Waveshare PV+
  2. Battery: 18650 protected pack → Waveshare BAT+/BAT- (show polarity)
  3. Waveshare outputs → buck / 5 V / 3.3 V rails → Pico / ESP32
  4. Load switching: MOSFET driver (D4184‑M) → solenoid with diode across coil
  5. Safety: fuses, blocking diode, grounding points

TODO: Upload schematics/solar_v1.pdf to docs/solar/schematics/ and replace this placeholder with embedded image or link.
