Engel fridge set up with solar enquiry
An Engel 40 litre fridge has a current draw of 0.5 to 2.5 AMPS Maximum according to the Engel web site. If you assume an average of 1.5 amps using the unit as a fridge, then the daily draw over 24 hours is 36 amp hours. A 100 watt solar panel will output approx 5.5 amps per hour (100 watts divided by the normal voltage of around 18 volts).
