Some RV owner may ask: “Is an inverter necessary for the RV or how to choose the right one."
Some reply: "No, it is OK to use small power appliance in the RV."
But, a senior RV owner also say: "The RV will have the same comfort as home. A delicious meal is very necessary. I used a 12V car rice cooker before, and it works really slowly, and the cigarette lighter is relatively hot. I feel very upset about it. Now I buy a pure sine wave inverter. When necessary, I can stop and connect the inverter to the car battery directly and use it at idle speed. Thus, I can buy a small electric pressure cooker and prepare the dishes in ten to twenty minutes. In addition, I can use a 120Ah lithium battery, which has the sufficient power to cook rice for 6-7 times. The portable gas stove can be used to prepare some simple dishes, and I will have the feeling of staying at home at any time.”
Some say that the inverter is not necessary, while some others say that it is required. Why is there such a difference? As a matter of fact, it depends on our electricity demand. The 12V battery of the RV can only enable electrical appliances with low power to work normally, such as 12V refrigerator and LED light, ventilation fan or small TV. If you want to use a high-powered electric appliance such as a rice cooker, a microwave oven, an electric kettle, or an induction cooker, you need a power inverter.
The inverter is to convert the 12V DC power of the RV to 110V or 220V AC power, which provides stable AC power for all the electric appliances in the RV. Most of the power inverters are 1000W, 2000W, 3000W, so what size of an inverter is suitable for the RV?
It depends on the actual load power of the RV. As to the high-power electrical appliances such as air conditioners and refrigerators, the starting current is equivalent to 3-9 times of the normal working current, and then it is required to select an inverter with higher power. Taking 3000W as an example, if the sum of the rated powers of the loads to be used in the RV at the same time is no more than 2800W, the 3000W can guarantee stable current. It should also be noted that in order to prolong the service life of the inverter, do not operate it at full load for a long time, and do not use the inverter in a condition exceeding 80% of the rated power.
What problems should I pay attention to when using the inverter in the RV?
First of all, the output voltage of the inverter is 110V or 220V AC, and the RV has a small space and is moving status, so measures should be taken to prevent electric shock.
Secondly, the operating environment temperature requirement of the inverter is not higher than 40℃, and the power should be cut off when it is not working.
Thirdly, please ensure that the working environment of the inverter is ventilated and dry, and do not place anything around the inverter.
