How much power does a 12V Dometic fridge use?
Under normal conditions the 75DZW’s power consumption is modest (1.3 amps per hour), however, used in high ambient temps or without pre-cooling, the fridge can put a big drain on your battery.
How much battery power does a caravan fridge use?
Therefore 40 Watts (Fridge) divided by 12 Volts equals 3.33 Amps. Take this 3.33 Amps and multiply it by the number of hours it will be consuming power (estimated to be 16hrs for each 24 hour period) equals 54 Ahrs (Max of 80 Ahr, if running continuous for 24 hrs.).
How long will a 12V fridge last on a 100Ah battery?
A 100Ah lead-acid deep-cycle battery will run a fridge using 630kWh/year for 13.3 hours. 80% discharge is assumed, but at the recommended DoD of 50% the same 100Ah battery will run the fridge for 8.3 hours. A lithium iron phosphate 100Ah battery will run the fridge for 15.8 hours at 95% discharge.
What size battery do I need to run a 12V fridge?
The average fridge consumes 40 watts of electricity per hour which means 960 watt-hours of battery capacity would be needed to run a fridge for 24 hours. 960 watt-hours equates to 80Ah, so a 160Ah deep-cycle lead-acid battery discharged to 50% will be required.
How many amps does a 3 way fridge use on 12V?
Based on 150W, your fridge will draw a constant 12.5amps; there is no thermostat control on 12v. Unlike new 12v only fridges which use compressors and use as little as 2amps, the 3-way fridges use heater elements – use lots of amps.
How long will a 12 volt battery run a refrigerator?
In general, a 12V-50Ah battery can run a 2 cubic feet 12V fridge for 35 to 50 hours before it’s completely depleted. A 10 cubic feet RV refrigerator can run on the same battery for only 10 to 15 hours. However, it’s important to note that: Batteries should not be fully discharged.
How long will a leisure battery run a 12V fridge?
You’ll only get about 5-6 hours from an 85Ah battery on a 12v coolbox, so it’s not worth trying for camping. Get a 3 way (gas/12v/240v) powered fridge – they are much better.
How many amps does a Dometic fridge draw?
The fridge takes 5 amps. The panels produce up to 15 amps in total.
