Van-life daily Wh budget
Portable or semi-portable station as a bridge — not a full house lithium bank design. Focus: fridge + lights + devices.
WattNeeds defaults: inverter efficiency η=0.90, DoD=0.90, buffer=0.15.
One-liner: nameplateWh = (whPerDay × days × 1.15) / (0.90 × 0.90).
Always re-check continuous watts and surge against the station inverter.
Baseline day (example)
| Item | Wh/day |
|---|---|
| Compressor fridge (avg) | 300 |
| LED lights | 40 |
| Phones + laptop | 150 |
| Fan (evening) | 60 |
| Total | 550 |
1 day autonomy @ defaults → ~781 Wh nameplate. 2 days no recharge → ~1.6 kWh. Solar often replaces upsizing if you get consistent sun.
