Charger tested at 58.9 to 59.3 amps. Voltage input reads 0.3 volts low according to DVM and smart shunt. Arrived double boxed and fitted with closed cell foam. Slight blemish on decal. Will only turn on with extension switch. No cover for ac terminals. Cables about 6 feet and 1/0 manual calls for 3 feet 3/0. Comes with precharge resistor. Overall a good product. Didn't test ATS. 2/13/2025 update Worked very well last year, even ran A/C for 2 1/2 hours without stressing the battery bank. Just ordered the 2000 watt version for another camper. May 2025 update: 3000 watt almost a year in service and working great. Connected the 2000 watt and while it ran a 15k btu RV air conditioner, its a bit of a load. It will be great for dry camping and running a microwave or drip coffee maker. Expert Power has a great products for about half the price of others. Oct 1 update: Original 3000 watt has been through 2 high desert summers without problems. Just got a 2nd 3000 watt in and hooked up today, was a reduced price like new and working great for off grid shed power. Have to add 4th 100Ah battery and 2nd 325 watt solar panel. This runs 18 cu ft refrigerator and shop tools. Can't say enough how great these inverters are from ExpertPower. Review: Misinformed - I have an rv with a 300ah life po4 battery bank and they were hooked up to a 3000w renogy inverter which worked great, but not after the sun would go down my battery's would drain really fast. so I was hoping to find an inverter that would allow the lithium battery's to drain to 2v or something. And I was under the impression that this inverter did that. I was very disappointed to find once the battery's reached 10.5 the alarm would sound and eventually shut itself off. I have a home battery system that drains the battery's to 10 percent that's why I believed an inverter that is compatible with lithium battery's would do the exact same thing. ## Features - Wide-Spectrum Compatibility: The ExpertPower Pure Sine Wave Inverter/ 80A Adjustable Charger is designed to meet the needs of all battery systems including AGM, Wet, Gel, and LiFePO4 with 8 profiles and built-in 30A transfer switch with UPS functionality that automatically switches between shore power and battery power in an industry leading 5ms. - Intelligence Driven CPU: An LED display provides a methodical user interface that streamlines data on system status (i.e. Priority Mode, Frequency, Error Codes) and battery status (i.e. voltage, load) in an easy to understand way without compromising its practical capabilities of 90-99% efficiency.

It was professionally installed, tested to confirm it powered up, and then left untouched until I finally needed it last week—less than a year later. Now, it’s completely dead. The screen no longer turns on, there's absolutely no AC output, and the inverter won’t respond to resets. I’ve thoroughly checked all external fuses and wiring—no issues there. This wasn’t a case of overloading or misuse; it simply stopped working before ever being put into service. I expected better reliability for a product in this price range, especially from a brand with so many positive reviews. Right now, I feel like I paid for a 3000W paperweight. ExpertPower, I hope you monitor your reviews. If you stand behind your warranty and product quality, I’m asking you to make this right. I’m open to updating this review based on your response and support. ## Frequently Bought Together - ExpertPower 3000W Pure Sine Wave Inverter Charger | Peak 9000W | DC 12V - AC 110V | LifePO4/ Lithium Battery Compatible | Auto Transfer Switch | LCD Display - DIHOOL Solar Panel Disconnect Switch, Non Polarized DC Circuit Breaker, 30 Amp, 2 Pole, 12V-400V, AC Disconnect Box Outdoor, Battery Cutoff Isolator - TKDMR 10pcs 1/0 AWG-3/8 Battery Lugs,Heavy Duty Wire Lugs,Ring Terminals,Battery Cable Ends,0 Guage terminals,Battery Terminal Connectors with 10pcs 3:1 Heat Shrink Tubing --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/245194144-expertpower-3000w-pure-sine-wave-inverter-charger-peak-9000w-dc](https://www.desertcart.us/products/245194144-expertpower-3000w-pure-sine-wave-inverter-charger-peak-9000w-dc) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-21*
