Under normal conditions the power consumption of the 75DZW is modest (1.3 amps per hour), but operation in high ambient temperatures or without cold can lead to a deep discharge of the refrigerator battery.
If you don’t know the actual load of your RV, there are some general rules you can apply. A typical RV refrigerator requires 600 watts to start and 180 watts to run. Slow cookers require 170 to 270 watts to start and run, while a 650-watt microwave oven needs 1000 watts from start to finish.
So, if your refrigerator (or other device) uses 30 amps a day, consider having a 90 amp battery and a solar panel of around 80 watts or more to make sure you don’t run into any problems.
Watts / volts = amps per hour A slightly different example is a 60 watt refrigerator that runs on a 12 volt power source and consumes 60/12 = 5 amps, but only with the engine running.
When someone zojuist had signed the Koelkasten Eigenlijk een 12 volt system zijn, zoals tub for 220/240 stroom ontvangt, de transformer in Engel het ontvangen capable of 12 volts, en dus geeft 12V x 2.5 amps for 30 watts at a time.
It is your lasting effect. A refrigerator engine also needs about three times more shaking power to start, but that boost is required in just a fraction of a second. To make this refrigerator work, you need an inverter that can handle 600 watts over a long period of time and a wave of 1800 watts in a split second.
A RV refrigerator can be used while driving. Although there are concerns about using propane while driving, it is still possible. You can also set the RV refrigerator to use battery power, which is usually enough to keep it running until you hit the target.
Typically, a battery is rated for a 20 hour cycle. For example, a 160 amp battery could theoretically deliver 8 amps per hour for 20 hours. Most solar batteries provide enough power for a refrigerator and other appliances.
I also need to use the inverter to run the refrigerator when plugged into a 110 outlet. All you want to do if you leave the refrigerator on is to increase the amount of energy it uses. As a general rule, turn on the RV refrigerator 24 hours before camping.
A decent refrigerator of this size below 30 degrees Celsius shouldn’t use more than 30-40 amps per day. Normal deep cycle batteries last around 1500 times if only 30% of their capacity is used.
If you max out the 2000 watt inverter, you are using 2000 watts / 12 volts = 166.6 DC amps per hour. If using a 12 volt, 200 A battery, divide the battery by 200 A / 166.6 A = 1.2 hours of driving.
Multiply 12 volts by 100 Ah and the result is 1200 amps now.
You have four solar panels with a total power of 1000 kilowatts. So it can produce 1 kilowatt of electricity per hour.
For example, find the refrigerator voltage and current, you will see 115V and 6.5 amps. By multiplying these two numbers you will know how many watts the refrigerator is using in this case, 747.5 watts. Smaller fridges typically use around 350 watts, while larger models use up to 780 watts.
For example, if a 300-watt (0.3 kW) solar panel actively generates electricity for an hour in direct sunlight, it generated 300 watts (0.3 kWh) of electricity. The same 300-watt panel produces 240 volts, which equates to 1.25 amps. Unfortunately, solar panels do not produce a constant flow of electricity throughout the day.
To get 3000 watts of 120-volt alternating current from an inverter, you need to replace the 100-amp generator with an expensive 250-amp generator and install LOTS of high-capacity batteries. In addition, 50 amps are required to power vehicle accessories, lights, gauges, etc.
AmpHour app to measure battery capacity
- 12V battery solar panel typically charges 13.6V to 17.0 volt to charge 12V battery or use 12V devices.
- A standard solar panel size is 65 "x 39", which is typically used to charge a 12 V 100 watt battery.
