ECO mode - economical and quiet:
When to use ECO?
- ✅ Maintaining the temperature of already chilled products
- ✅ Night operation - minimizing noise while sleeping
- ✅ Long periods without power - maximizing operating time
- ✅ Stable conditions - moderate ambient temperature
- ✅ Priority: saving energy and battery life
ECO mode parameters:
- Consumption: approx. 0.19-0.21 kWh/24h
- Consumption: approx. 3.5-4.5A at 12V
- Noise: minimal, very quiet
- 80Ah battery life: 17-22 hours
MAX mode - maximum power:
When to use MAX?
- ✅ Rapid cooling of freshly purchased warm products
- ✅ High ambient temperatures (+35°C and above)
- ✅ Freezing fresh products down to -20°C
- ✅ High thermal load - full refrigerator
- ✅ Start your journey - quickly reach the target temperature
- ✅ Priority: efficiency and speed
MAX mode parameters:
- Consumption: approx. 0.24-0.27 kWh/24h
- Consumption: approx. 5-6.5A at 12V
- Noise: normal for a refrigerator
- Life on 80Ah battery: 12-16 hours
Optimal strategy - combination of modes:
Daily example:
- Morning (7:00) - MAX for 30-60 min to start
- On the road (8:00-18:00) - ECO, the engine charges the battery
- Lunch time (1:00 PM) - if adding warm products: MAX for 20 min
- Evening (6:00 PM - 10:00 PM) - ECO
- Night (10:00 PM - 7:00 AM) - ECO for quiet operation
Result: 15-20% energy savings with complete comfort!
Range -20°C to +10°C - maximum versatility
