How to Choose A Suitable Inverter for Your RV

Many people like to drive their own RV in warm weather and take their family to camp in the wild. Ample power is required throughout the outdoor activity. Many people are considering using inverters to make all AC equipment work properly so that their families can fully enjoy the outdoors. However, the challenge is how to choose a suitable inverter to keep the AC equipment properly and adequately powered. In general, the inverter brand, size and type are the main reference points for selecting an inverter.
How to Choose An Suitable Inverter for Your RV
Our recommendation for the inverter brand is to choose an inverter with a good operating record from an inverter manufacturer that has been operating for many years and has ETL, CE or UL certification to ensure that they can be in your RV vehicle runs safely. The size required for your application will depend on your particular needs and the estimated power consumption of your RV. Keep in mind that unlike the AC load in our home, the RV load may have to be monitored and adjusted so that it does not exceed the rated output power or quickly drains the battery. Depending on the size, most RVs/leisures should be operated on inverters rated at 2000 to 4000 watts (continuous). Typically, the inverter will provide a peak load of 2 to 3 times its rated continuous output power to support the high surge power requirements of starting loads such as refrigerators and compressors.

The type of inverter also needs to be considered. Many new devices require a pure sine wave inverter with a clean output that is the same as the power we get from a socket in the home, and many older inverters are modified sine wave inverters that may not be available in today's sensitive electronics. Used on equipment/load. With the popularity and usage of pure sine wave inverters continuing to increase, the price of pure sine wave inverters has also dropped slightly, but the price of modified sine wave inverters is usually cheaper. Another option is a high-frequency inverter with a power frequency inverter or a transformer-based inverter. High-frequency inverters are more predominate in the lower end and lower power inverters and utilize electronics to convert DC battery power to AC.  These high-frequency inverters are generally lighter in weight and less expensive but do not provide sufficiently high peak power for compressors and motors. Transformer-based inverters, on the other hand, can withstand higher peak loads, which are typically larger, heavier and more expensive due to the large amount of copper that makes up the majority of the transformer.

Most RVs are equipped with a converter that sends AC power to the load at home and charges the battery when it is plugged into the shore power. However, most converters are not known for their excellent battery chargers, and long periods of battery insertion often overcharge the battery. In most cases, they should not be fully used to charge AGM or Gel batteries. Therefore, when selecting an inverter for an RV, it is best to choose an inverter charger. The inverter charger can replace most converters and is equipped with an internal transfer switch in many brand inverters, which performs all the functions of the converter. Replacing the converter with an inverter charger can save some complicated wiring and simplify the installation process. It can support 3 times of rated power and can drive all types of loads to charge the battery and power the load.

After calculating and breaking down all of these options, don't forget that you will need enough battery capacity to keep these inverters running and the AC equipment running. Generally, a larger inverter size means more battery capacity is required.
