The Ultimate Guide to RV Power Inverters

Are you considering investing in a power inverter for your camper or RV?

RV inverters might seem confusing initially, but this guide will help you navigate the various options and select the perfect one for your needs.

Below, you'll find everything you need to know about RV inverters.

An RV inverter is a device that converts direct current (DC) electricity from your RV's batteries into alternating current (AC) electricity. This allows you to power household appliances and electronic devices while on the road or camping without shore power.

Most RVs have built-in electrical systems that operate on DC power supplied by the batteries. However, many common devices--such as laptops, TVs, and kitchen appliances--require AC power to function.

Although often used interchangeably, inverters and converters are distinct devices with different functions.

Here's a breakdown of their key differences:

• Purpose: Converts DC power from the batteries into AC power to run household appliances off-grid.
• Functionality: Transforms 12V DC from the battery bank into 120V AC, mimicking standard household outlet power.
• Use Cases: Ideal for boondocking, dry camping, or anytime you need AC power without a generator or shore connection.

• Purpose: Converts 120V AC power (from shore power or a generator) into 12V DC power.
• Functionality: Charges the RV's batteries and powers DC appliances and accessories when connected to an external AC source.
• Use Cases: Essential when plugged into a campground electrical hookup or running a generator to maintain battery charge and support DC systems.

Before purchasing an inverter, it's important to understand the different types available.

Here are the main varieties:

Square wave inverters are the most basic and affordable type but come with significant limitations.

Key characteristics include:

• Waveform Shape: Outputs a square wave with abrupt voltage transitions.
• Compatibility: Not suitable for sensitive electronics (e.g., audio equipment, digital devices).
• Efficiency: Generally less efficient and produces more heat during operation.
• Applications: Best for simple tools or basic appliances in non-sensitive environments.
