Tips
- →LiFePO4 is mandatory for daily RV cycling — Li-ion degrades too fast
- →Oversize solar by 30-50% for cloudy days and non-ideal panel angles
- →Use 12V DC appliances where possible to skip inverter losses (10-15% savings)
- →Check your power station's max solar input — this is often the bottleneck
- →Consider expandable systems — start with 2kWh, add batteries later
- →Fridge duty cycle is ~50%, so real draw is about half the rated watts
