Before you buy
Power Requirements Calculate your total wattage needs. Add up the watts of devices you will run simultaneously. Choose an inverter with a continuous rating above that. Consider surge needs for motors and compressors.
Pure Sine vs Modified Sine Pure sine wave is essential for sensitive electronics. It also runs motors quieter. Modified sine wave is cheaper but may cause issues. For RVs, pure sine is recommended.
Size and Installation Measure your available space. Compact models make installation easier. Look for units with mounting flanges. Ensure proper ventilation to prevent overheating.
Safety Features Look for overload protection, low voltage shutdown, and thermal protection. These features protect your inverter and your RV’s electrical system. Remote controls add convenience.
Common questions
What size inverter do I need for my RV?
It depends on the devices you plan to run. A 1000W inverter can handle basic electronics. A 2000W inverter runs a microwave. A 3000W inverter can start a small air conditioner.
What is the difference between pure sine wave and modified sine wave?
Pure sine wave produces clean power like your home outlet. Modified sine wave is a stepped approximation. Sensitive electronics may malfunction with modified sine wave.
Can I install an inverter myself?
Yes, if you have basic electrical knowledge. Follow the manufacturer’s instructions. Use proper wire gauges and fuses. If unsure, hire a professional.
How many batteries do I need to run a 2000W inverter?
A 2000W inverter draws about 166 amps at 12V. To run for an hour, you need at least 200Ah of battery capacity. Consider your usage time.
Do inverters drain the battery when not in use?
Most inverters have a standby mode that draws minimal power. However, it is best to turn off the inverter when not in use to prevent drain.
Can I run a hair dryer with a 1000W inverter?
Hair dryers typically require 1500W to 1800W. A 1000W inverter is not sufficient. You would need a 2000W or larger inverter.
What is surge power?
Surge power is the temporary burst an inverter can provide to start motors. It lasts a few seconds. This is important for refrigerators and air conditioners.
Are these inverters safe to use inside an RV?
Yes, they are designed for indoor use. Ensure proper ventilation and avoid covering them. Install them away from flammable materials.
The verdict
For most RVers, the Renogy 2000W Pure Sine Wave Inverter is the best balance of size, power, and reliability. If you need more surge capacity or prefer a premium brand, the Xantrex FREEDOM X 2000 is worth the investment. For a budget pick, the AIMS Power 2000W offers pure sine wave without breaking the bank.
