What Does an RV Inverter Do?

An inverter converts your battery bank's 12V DC power into 120V AC household power. That's what lets you run things like coffee makers, microwaves, laptops, and CPAP machines when you're not plugged into shore power. Without an inverter, your batteries can only run 12V devices like lights, water pumps, and USB chargers.

There are two types you'll run into. Modified sine wave inverters are cheaper but produce a rough approximation of AC power. They'll run basic loads fine, but they can make electronics buzz, damage sensitive equipment, and make motor-driven appliances run hotter than they should. Pure sine wave inverters produce clean power that's identical to what comes out of a wall outlet. According to Aims Power, pure sine wave is the only safe choice for sensitive electronics and medical devices.

We install standalone inverters and inverter/charger combos from Victron, Aims, and other reputable brands. Every installation includes properly sized DC cabling, Class T fusing, and a remote panel if your unit supports one. We do the work at your location anywhere in Palm City and Martin County.

TL;DR

An inverter turns your 12V battery power into 120V AC so you can run household appliances off-grid. A 1000W install runs $225-425, 2000W costs $375-650, and 3000W+ runs $500-900. Pure sine wave is strongly recommended over modified sine for clean, reliable power.

What's Involved in Inverter Setup

1

Load Calculation

We add up the wattage of everything you want to run, including startup surge for motors and compressors. This determines the minimum inverter size you need.

2

Mounting and Cabling

The inverter gets mounted in a ventilated space near the battery bank. We run heavy-gauge cables (often 2/0 or 4/0 AWG) to minimize voltage drop and heat buildup at high current draw.

3

Fusing and Protection

A Class T fuse goes between the battery and inverter for short-circuit protection. We also install a battery disconnect switch for safety when servicing the system.

4

AC Wiring and Test

The inverter output gets wired to a dedicated sub-panel or selected circuits. We load test with your actual appliances and verify clean power output with a meter.

When You Need an Inverter

If you've been running the generator every time you want a cup of coffee, an inverter changes everything. Here's when it makes sense:

Inverter Setup FAQs

How much does RV inverter installation cost in Palm City?

A 1000W inverter setup runs $225-425, a 2000W unit costs $375-650, and a 3000W or larger inverter runs $500-900. Price includes the inverter, heavy-gauge cabling, fusing, and mounting. Inverter/charger combos are at the higher end because they replace your converter too.

What's the difference between pure sine wave and modified sine wave?

Pure sine wave inverters produce clean AC power identical to what comes from a wall outlet. Modified sine wave inverters produce a stepped approximation that works for basic loads but can cause problems with sensitive electronics, CPAP machines, and appliances with motors. Pure sine wave costs more but runs everything without issues.

What size inverter do I need for my RV?

Add up the wattage of everything you want to run simultaneously. A coffee maker uses about 900W, a microwave 1,000-1,200W, a hair dryer 1,500W. If you only need to run one thing at a time, a 1,500-2,000W inverter covers most needs. If you want to run multiple appliances, you'll need 3,000W or more. We also factor in surge watts since motors draw extra power at startup.

Will an inverter drain my RV batteries quickly?

It depends on what you're running and your battery bank size. A 1,000W load pulls about 83 amps from a 12V battery bank. A single 100Ah lithium battery would last roughly an hour at that rate. The key is matching your inverter size to your battery capacity and solar input. We calculate the math during installation so you know your real-world runtime.

Can I run my RV air conditioner on an inverter?

You can, but it takes serious battery capacity. A typical 13,500 BTU RV AC draws about 1,200-1,500W running and 2,500-3,000W on startup. You'd need at least a 3,000W pure sine inverter and 400Ah or more of lithium batteries to run it for any reasonable amount of time without solar input. It's doable, but it's a significant system investment.

What's an inverter/charger combo and is it worth it?

An inverter/charger combines an inverter with a built-in battery charger and automatic transfer switch. When you plug into shore power, it charges your batteries and passes AC through to your outlets. When you unplug, it automatically switches to inverter mode. Victron MultiPlus is the gold standard for RVs. It's worth it if you want a clean, integrated setup without separate components.

Want AC Power Without the Generator?

We'll size the right inverter for your needs and install it with proper cabling and protection. On-site service across Martin County.
