Works quite well in my RV. Hardest part was lifting it as it has some heavy transformers apparently. Replaced the inverter that the RV came with and reused all the wiring so pretty simple.

I purchased the ExpertPower 3000W inverter on June 21, 2024. 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.

I bought 2 other inverter charges from someone else and they both stopped working in 5 min. this one works great, i have 0 problems with it working, the controller is complete junk, does not stay on, always cycles from welcome screen to info screen that gives you almost no info. Shows % not watts, also does not show % of battery life or even maybe a % left. just current volts. and that screen shuts off quickly.

I've been using this unit for over a week now, and it's working as expected with one 200AH LIFEPO4 battery. I haven't had any issues with it, it looks solid.

All around good inverter. Has a decently clean sine wave and does rated power easily. Meets and sometimes exceeds the 60amp charging current. Only real issues I have is the accuracy of the readings on the screen are off by a few volts. As well as it only outputs 108-110vac. Not a huge issue with most things but I'd prefer to see 115-120v output.

We purchased the ExpertPower 3000 inverter charger to replace a different, well-known brand that came stock in our Class A RV. The previous unit only produced a square wave, which was damaging our appliances and electronics. In contrast, the pure sine wave output from this model has been outstanding, even with our most sensitive devices.We boondock occasionally and have a 5KW battery bank powering this inverter. While boondocking, we use power save mode, which consumes just 10 watts at idle and performs flawlessly with no issues observed. In parks, we switch to normal mode, where the idle standby consumption is 90 watts. The power transfer remains seamless when connecting to shore power or switching to a generator. During storm-related power outages, the transition was so smooth that we didn’t even notice the power had gone out.We opted for the model with the remote display, which fit perfectly into the same location as the old unit’s display, making installation a breeze. The remote display makes it easy and convenient to keep tabs on the system’s status, including battery levels and operational modes, at a glance.Once, we accidentally ran the batteries down to the 10.5V cutoff, at which point the alarm kicked in as expected. The inverter handled the situation well and protected our system without any issues. The surge functionality has also proven reliable—once, we accidentally ran more appliances than the system should have handled, and it managed the load without a problem.Installation was straightforward; the inverter fit perfectly into the existing basement cabinet and wired in without complications. The charging function works as advertised, efficiently maintaining our battery bank. Configuration was simple, and the build quality has been excellent. It has already endured cross-country trips in extreme summer heat and winter cold without a hitch.Compared to other options with similar specifications, particularly the more expensive “blue” brand, this unit has delivered exceptional value for the price. We initially purchased one of the popular blue models but ended up returning it and opting for the ExpertPower 3000 instead. This choice has more than paid off in performance and reliability.

We have wanted to boondock and camp in locations and parks that don’t have electric hookups and up to now have only had the standard 12 volt lead acid battery on our travel trailer. This year we decided to upgrade to lithium batteries with the goal to also add solar down the line. In researching the switch to lithium I knew I needed a lithium-compatible charger and also an inverter and so I began looking for an all-in-one inverter charger. I came across ExperPower’s website and liked what I saw about their customer service and support and the specs for their inverter chargers. I installed this inverter charger along with 400 Ah of lithium batteries and everything is working great. The charger replenishes the batteries from 10 to 15% charge to 100% very quickly and the cooling fan is thankfully fairly quiet (appreciated since it’s mounted in the under-bed storage area.) The unit is robust, built very well and the battery posts and AC inputs and outputs are high quality and heavy duty so no worries about stripping a bolt or terminal when tightening down the connections. What I REALLY appreciate is the long cable for the remote switch; I was able to mount it just below the control panel adjacent to the trailer’s door with cable left over. Very happy with our purchase!
