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 Hardcastle's RV Editors
10 min read4 products evaluated
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.

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.
What Matters Before You Choose a 50 Amp RV Inverter Charger
Key buying criteria so you get the right fit the first time.
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.
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.
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.
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.
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.
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 bullets. 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.
Match a 50 Amp RV Inverter Charger to Your RV
By Shore Power Setup
| Your situation | Recommended pick | Why |
|---|---|---|
| 50-amp coach with two heavy legs | Go Power Advanced | Dual-leg 50A transfer switch is named in the listing |
| Full 100A shore service, roof AC | Go Power IC Series | 100A transfer switch with published surge |
| Mixed 30A and 50A campground hookups | Go Power IC Series | Works with both 30A and 50A services |
| RV-C coach with a display panel | Xantrex XC Pro | Communications card supports RV-C and J1939 |
| Want a remote panel in the box | GP-IC3000 Remote | Package includes a remote |

By Budget
| Budget | Recommended pick |
|---|---|
| Under $1,550 | Xantrex XC Pro at $1,499.98 |
| $1,550 to $1,700 | Go Power Advanced at $1,596.77 |
| $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 in the bullets.
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.
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 in the bullets, 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.
