Review: Excellent Inverter Upgrade with Smooth Power and Great Value - 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.
Review: Expert Power 3000 watt and 2000 watt inverters - Tested inverter with 400 Ah battery bank ran up to 3kW with no problems. 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.

## 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. Power-Save mode consumes max. 10W with no load.
- Convenient Prioritization: The inverter-charger includes priority settings that automatically switch between shore power and battery power to easily charge your battery system with ease and even able to be utilized without battery hookup for shore-power-only maintenance days, ensuring your power is ready when you need it. The package also includes a 26ft Smart Controller that allows you to adjust the inverter's settings from any comfortable range within your RV/Camper.
- Premium Quality: The unit is composed of a clean-cut, steel-hardened iron case equipped with copper terminals and a double ball-bearing fan for maximized low-audibility cooling of the unit under high-power loads.
- System-Wide Protection: The CPU utilizes a complex series of algorithms that detect dangerous conditions protecting both the unit and your battery system from overloading, overcharging, overheating, deep discharge, and short circuits for full peace of mind.
