The SunGold Power 4000W DC 24V Pure Sine Wave Inverter With Charger Delivers 4000 Watts of 120V Power From a 24 Volt Battery Bank
The SunGold Power 4000W DC 24V Pure Sine Wave Inverter With Charger is a single phase, low frequency inverter charger from SunGold's LFP series. It turns 24 volt battery power into 120 volt pure sine wave AC, recharges the batteries at up to 50 amps whenever grid or generator power is connected, and transfers your loads between AC input and battery power automatically.
The 24 volt design keeps DC current manageable at 4000 watts, so the cabling is lighter and easier to route than a 12 volt system of the same size. It is a good match for cabins, RVs, work vehicles, and home backup systems that need more than 3000 watts of 120 volt power.
SunGold Power 4000W DC 24V Pure Sine Wave Inverter With Charger Features
4000 Watts Continuous and 12000 Watts of Surge
A low frequency transformer design gives this inverter a 300 percent surge rating, up to 12000 watts for 20 seconds. That is the reserve you need to start refrigerators, freezers, pumps, compressors, and shop tools, while 4000 watts of continuous output keeps several household loads running together.
50 Amp Three-Step Charger
The integrated charger delivers up to 50 amps (±5A) using a 3-step intelligent profile, with 9 battery type settings for lithium, AGM, gel, and flooded batteries. The charge current is adjustable from 0 to 100 percent and the charger can be turned off.
10 Millisecond Typical Transfer
If grid or generator power is lost, loads are moved to inverter power with a typical transfer time of 10ms. The AC input range can be set to 90 to 135VAC or 100 to 135VAC with SW2 to suit your generator or utility supply.
AC Priority, Battery Priority, and Automatic Generator Start
AC priority is the default for backup use. Battery priority, set with SW5, lets a solar-charged battery bank run the load first. The inverter can also start a compatible generator when the battery runs low and shut it down after charging.
LCD Display, Remote Control, and BTS Cable
An LCD display shows system status, and SunGold includes a remote control and battery temperature sensor cable. Power saver mode lowers idle consumption from 48 watts to 19 watts, and output frequency can be set to 50 or 60Hz with SW4.
Real-World Applications
Off-grid cabins. Run a refrigerator, well pump, lights, and kitchen appliances from a 24V battery bank, with generator support when needed.
Home backup. Keep 120V essentials such as refrigeration, furnace blowers, and networking equipment powered during outages.
RVs and specialty vehicles. Supply household AC from a 24V house battery and recharge from shore power.
Mobile workshops. Power saws, compressors, and chargers on job sites without running a generator all day.
How It Compares to Common Alternatives
Versus the 3000W 24V model. The 4000W version adds 1000 watts of output, a 12000 watt surge, and a 50 amp charger.
Versus the 4000W 24V split phase model. The split phase version requires 240VAC input and adds 240V output for appliances like well pumps and dryers. Choose this single phase model if all of your loads are 120V.
Versus all-in-one solar inverters. SunGold confirms this unit has no built-in solar controller, so solar panels need an external charge controller.
Is This Inverter Charger the Right Fit
Battery voltage. Requires a 24 volt battery bank.
AC service. 120VAC input and 120VAC single phase output.
Load size. Continuous loads up to 4000 watts with surges up to 12000 watts.
Space. Plan for a 22 x 9.1 x 7.5 inch, 54 pound unit near the batteries.
This may be a good fit if
You have or plan a 24V battery bank
Your loads are all 120V
You need strong surge capacity for motors
You want charging, transfer, and generator start in one unit
Common Questions
Can I Connect Solar Panels Directly?
No. SunGold says this inverter has no built-in solar controller, so an external solar charge controller is required.
What Is the Idle Power?
Idle power is 48 watts with power saver off and 19 watts with power saver on.
Does It Work With Lithium Batteries?
Yes. Select the appropriate battery type setting for your 24V lithium bank.
Does It Provide 240V Output?
No. This is the single phase 120V model. SunGold offers a separate 4000W 24V split phase version for 120/240V systems.

Installed this on a portable system for roll around convenience.
It was easy to install and wire up and powered right up with no issues.
Hi Randall, thank you for sharing your experience! We're glad to hear the inverter worked well for your system. If you need any more assistance, feel free to reach out. Enjoy your power setup!
Thank you for the 5-star review! We’re glad you’re enjoying your Jackery setup, and we really appreciate you sharing the photo. It looks like a great setup!
Jackery performed well, durable, easy to use, recommend
The Jackery was my first power station. I had a lot to learn and much research to do. Outbound Power was easy to work with, they answered the phone and helped with the delivery. We used it constantly on our first camping trip with it, powering our 12v cooler, charging phones and LED lights. No issues at all. Product is well built, durable and easy to understand. Might even get the solar panels later this year. I'd recommend.
Hi Gordon, thank you for sharing your experience! We're thrilled to hear the Jackery served you well on your camping trip. Enjoy exploring with your power station, and we'd be happy to help with the solar panels when you're ready. Safe travels!
This is the first power station I have owned. I chose the Anker Solix c1000 gen 2 because it had great reviews and was the size I wanted. I live in central California and fortunately we do not have a lot of power outages. With winter coming, I decided to prepare just in case. Ordering the product was easy and Outbound Power had the best price.
The only issue I had was registering the product. Anker provided a QR code which is pretty standard. However, I had to call Outbound Power to get a working link. The gal I spoke to at Outbound seemed surprised I had to call.
Hi Dallas, thank you for sharing your experience! We're glad you chose the SOLIX C1000 and that you found ordering easy. We appreciate your feedback about the registration process and will work to improve it. Stay safe and enjoy your power station!
Outbound Power makes the buying experience so easy
Outbound Power makes the buying experience so easy. If they don’t already have the best price, they have always beat the best price. Great company, fantastic communication.
Hi Dustin, thank you for your kind words! We're thrilled to hear you had a great experience and appreciate your support. Looking forward to serving you again!
