4 Best 50 Amp RV Inverter Chargers in 2026: A Practical RV Guide

Four 3000W inverter chargers with 50A transfer switching compared on charger amps, surge, pass-through legs and remote control, from $1,500 to $2,021.

By Bowen HigginsRV Editor at RV Gear Lab4 products comparedSpec-sheet researched

The 50 amp in this category describes the transfer switch, not the inverter. An RV with 50-amp service brings in two 120V legs of up to 50 amps each, and the inverter charger has to pass both through to the coach without melting a relay, then swap to battery power when shore power drops. A 3000 watt inverter on its own supplies only about 25 amps at 120V, so the pass-through rating and the charger size matter as much as the headline watts.

We compared four 3000W inverter chargers priced from $1,499.98 to $2,020.88 that advertise a 50A transfer relay or dual 50A legs. We read each listing for charger amps, surge capacity, pass-through legs, remote or app control and warranty, and we flag where a listing is silent on idle draw, efficiency or neutral-to-ground behavior, which are the numbers competitors rarely show.

RV Gear Lab field notes

The Rig Fit Check

Start with the job: Xantrex 818-3010 Freedom XC Pro 3000 Inverter/Charger leads this shortlist for RV-C coaches wanting the biggest charger per dollar. Use that fit as a reference point, then compare the alternatives against your own space and workload.
Specs that separate the picks: The first details to compare are 3000W, 150A charger, 3000W pure sine wave, 3000W, 6000W 1-sec surge. Confirm the exact model and included components before ordering.
Trade-off to plan for: Idle draw and efficiency are not published

Before you buy

What Matters Before You Choose a 50 Amp RV Inverter Charger

Key buying criteria so you get the right fit the first time.

01
Pass-through rating and legs
A 50-amp RV service carries two 120V legs, each up to 50 amps, and the transfer switch must carry both without overheating. A single 50A relay rating, as on the Xantrex, is not the same as a dual-leg 50A switch named in the Go Power listings. Find the exact wording in the listing and check the manual for how each leg is wired before you rely on it for a full coach.
02
Inverter watts versus amps at 120V
A 3000W inverter supplies about 25 amps at 120V, since 3000 divided by 120 is 25, which is half of a 50A leg. That means the inverter alone cannot run everything a 50-amp coach can on shore power. Decide which circuits will be inverter-fed, and use the listing's output wattage, not the transfer rating, to size them.
03
Charger amps at 12V
A 150A charger at about 12V delivers around 1,800 watts of charging power, while a 125A charger gives roughly 1,500 watts. The difference determines how fast a large lithium bank refills on a generator. Look for the charger current in the bullet points, and check your battery's maximum charge current so you do not exceed it.
04
DC current and cable load
At full 3000W load on a 12V system, the battery side draws roughly 250 amps at 100 percent efficiency and more in practice, an estimate from watts divided by volts. That means thick cables, a proper fuse and a bank whose battery management system can deliver the current. Check the manual for required wire gauge and fuse size, since the listings here do not state them.
05
Surge and motor starting
A roof air conditioner draws far more at startup than while running, and an inverter must cover that burst. The Go Power IC Series lists 4800W for 5 seconds and 6000W for 1 second, and the Xantrex lists 2x output for 5 seconds. Compare those figures to your AC's rated starting load before relying on inverter power for it.
06
Idle draw, neutral-ground and thermal derating
An inverter charger sitting on shore power still draws some battery power, and the number is rarely in the listing. Neutral and ground switching also matters when you switch between shore, generator and inverter, and heat can lower the real output. Look for no-load draw and bonding behavior in the manual, and ask the seller if the listing is silent.

Methodology

How We Built This Shortlist

Each pick was assessed across 5 criteria weighted for real-world use.

Transfer switch and pass-through

We checked whether each listing names a single 50A relay, a dual-leg 50A switch or a 100A transfer, since the coach's two 120V legs need to pass through together.

Charger amps and recharge time

We compared charger current, 125A versus 150A, and estimated what that means at 12V using plain arithmetic, about 1,500 to 1,800 watts of charging.

Surge and motor-load behavior

We looked for published surge ratings and durations, since a roof air conditioner needs a short burst far above its running draw.

Monitoring and remote control

We noted Bluetooth, RV-C, a remote panel or firmware updates, and how each listing says the unit is controlled.

Disclosed gaps

We recorded which numbers each listing leaves out, such as idle draw, efficiency, neutral-to-ground switching and warranty length.

$1,950 to $2,050	GP-IC3000 Remote at $2,000.67 or Go Power IC Series at $2,020.88

Larger Charger vs Included Remote

Larger charger

A 150A charger puts roughly 1,800 watts into a 12V battery bank, so a depleted lithium bank refills sooner. The Xantrex XC Pro and Go Power IC Series use 150A chargers.

Included remote

A remote panel lets you switch modes and read battery status from inside the coach without opening the compartment. The GP-IC3000 Remote ships with one at a 125A charger rating.

Most buyers with big lithium banks should default to a 150A charger and add a remote separately unless an included one saves a real cabinet trip.

By Monitoring Preference

How you want to monitor	Recommended pick	Why
Phone app plus RV-C display	Xantrex XC Pro	Bluetooth app and RV-C support in the listing
Firmware updates over the air	Go Power Advanced	Over-the-air firmware updates are stated
Physical remote with efficiency data	GP-IC3000 Remote	Remote included, over 90 percent efficiency
Rely on the manual, minimal electronics	Go Power IC Series	Straightforward 3-in-1 unit with documented ratings

For Lithium Batteries Specifically

Look for

A charger profile for lithium, wide DC input range and an adjustable low-voltage shutdown, plus a charger amp rating your bank can accept. 150A at 12V is roughly 1,800 watts, so confirm your battery's maximum charge current first.

In this comparison

The Xantrex XC Pro describes a wide DC input range and adjustable low-voltage shutdown, and its listing says it charges drained batteries from 0 VDC. The Go Power listings do not state lithium profiles.

When to Spend More

Spend more if

You want documented surge for a roof AC or the full 100A of shore power; the Go Power IC Series at $2,020.88 publishes both.

Save if

You mostly need charging and pass-through and are comfortable reading the manual; the Xantrex XC Pro at $1,499.98 offers a 150A charger and 50A relay for less.

FAQ

Before You Bring One Home

Does a 50 amp inverter charger mean a 12,000 watt inverter?

No. The 50 amp figure describes the transfer switch or pass-through, while the inverter itself is 3000W in these units, about 25 amps at 120V. The coach can draw up to 50 amps per leg from shore power, but only the inverter's wattage on battery.

Can I use a 3000W inverter charger with a 30 amp RV?

Yes, 30A-service coaches can use them, and the Go Power IC Series says it works with 30A and 50A services. You may not use the full 50A switching, so a cheaper single-leg 30A model might be enough.

Is the Go Power IC Series worth $520.90 more than the Xantrex XC Pro?

Only if you need the published surge ladder and the 100A transfer rating. Both have a 150A charger, and the Xantrex adds RV-C and Bluetooth for less.

How do I size the wiring for a 3000W inverter charger?

Divide 3000 watts by battery voltage to estimate DC amps, about 250 at 12V before losses, then follow the manual's cable gauge and fuse table. Keep cable runs short, and fuse near the battery.

Do these work with lithium batteries?

They can, but check the charge profile. The Xantrex listing mentions a wide DC input range and an adjustable low-voltage shutdown, while the Go Power listings do not state lithium profiles, so confirm with the manual.

What maintenance does an inverter charger need?

Keep vents clear, check cable tightness and torque annually, and update firmware where supported, such as the Go Power Advanced over the air. Test the transfer switch by unplugging shore power occasionally.
