Charging strategy
Model solar and DC-DC charging as separate sources
Calculate solar harvest and alternator/DC-DC contribution separately. That makes it clear whether the system remains viable during short winter days, extended stays, or no-driving periods.
Decision 01
State the driving assumption
Use expected driving hours and a conservative charging contribution. A plan should still show what happens if the vehicle does not move.
Decision 02
Check source compatibility
Verify voltage, current, temperature behavior, alternator limitations, and the charger documentation before buying.
Decision 03
Keep critical loads independent
Critical overnight loads need a battery reserve. Do not rely on tomorrow’s drive as the only resilience measure.
