WZRELB Power Inverter 3000W Pure Sine Wave Inverter 12V 120V Dc AC Converter

Got this a couple months ago with the pictured charge controller. I started it out at a 12v system when this pic was taken and moved it up to a 24v system where we used it the most. I powers out Keurig coffee maker #1 which I was happy about since every other inverter I've had would not work with. Got the small fridge hooked up, lights, Plasma TV (Power Hog), computers, phones, water pump, and works great with our washing machine but we do have a 120v washer dryer combo purchased at Wal-Mart but it will run that just fine. When using the Keurig I do notice the fan goes on full but we have it in our shed so we never hear it. I suppose if it was in the same room it might be a little annoying but that is a pretty big load at 3800 watts peak i believe and this is rated at 3000 watt. I even ran a microwave off of it but it seemed like the microwave was struggling a bit but it maintained. Not sure if that could be that our battery bank isnt all that huge with just 4 deep cycle marine flooded batteries. I decided it's probably not such a great idea to run the microwave until i test it again with more power but I would imagine that does put a big strain on it and the last thing you want is for it to go out. I would feel more comfortable with a 4-5000 watt for a microwave unless its an efficient mini. Overall it's attractive, tells you the voltage, and It's gotten down to about 21 volts before it starts to scream which is really good, and I know I shouldn't do that but... I always want to see the full range of something I own, just like my Car ;)

I have been using this inverter for over a year now in my Solar powered home office/studio. It has been completely steadfast and reliable. It is connected to three 120AH batteries, which are charged by 3 100W solarpanels. I use 3 foot heavy duty battery cables to connect the inverter to the batteries, through a Victron Energy Battery Protect that is set to disconnect the inverter if the batteries get down to 12v (which rarely happens). This powers my complete office/studio, which includes a Mac Mini, Macbook Pro, two large Dell monitors, Canon printer, lights, Yamaha 88key keyboard, Adam Audio powered monitors and various small electronic devices. It has worked beautifully and means my home office is virtually free of electricity charges.I had to contact the company for technical advice at one point, and was amazed that they replied the very next day. They were very helpful and provided all the information I needed. This has been one of my best experiences with electronic devices.

Update: Because of the high power draw I messaged the company to see where I can purchase a switch. They had great customer service and were able to send me a switch. It installed very easily and fit inside with no airflow concerns. Simply connect the battery ends to the appropriate lugs (from the inside of inverter) and solder the switch ends to the switch tabs. Remote works great from 25 feet away through two walls!I've been using this inverter for over 3 years now and still have had no problems. It has run circular saw, refrigerators, top loading washers, etc. Not all at once, but it has handled start up on all of them.It beeps loudly when overloaded, but resets quickly.The soft startup hasn't negatively affected any appliances when I accidentally have the appliance on when I turn on the inverter (as far as I can tell).I like the black sleek design. No crazy colors, shapes, or unnecessary lights.Very close to 5 stars but my only complaint is the power consumption (when on, but not in use). Just seems a bit excessive. It can take down the voltage of the 24v battery system by 0.6v or more just by being on.System:Two12v 200AH 4D Deep Cycle batteries (in series for 24v system)WZRELB 3000W Pure Sine Wave Solar Power Inverter Generator 24VSolarEpic 40A MPPT Solar Charge Controller 100V Input Tracer

The inverter in question delivers reliable performance, consistently powering connected devices without any operational issues. Its core functionality—converting DC to AC power—works as expected, making it a dependable choice for both residential and light commercial applications.Fan Operation and NoiseA notable aspect of this inverter is its cooling fan behavior. Approximately every 15 minutes, the fan activates and runs for an extended period. While this is a standard feature in many inverters to manage internal temperatures and protect sensitive electronics, the fan on this model is particularly loud. The noise level is significant enough to be noticeable in adjacent rooms or quiet environments, and may be disruptive for users seeking a silent or low-noise installation.This pattern of frequent, loud fan operation is not uncommon among inverters, especially those with high power output or those installed in warmer environments. The fan is typically triggered by internal temperature sensors and is essential for maintaining safe operating conditions, especially during periods of higher load or elevated ambient temperatures. However, the volume and frequency of the fan's operation can detract from the overall user experience, particularly in noise-sensitive settings.Potential Causes and ConsiderationsThermal Management: The fan's frequent activation suggests the inverter is either working near its thermal threshold or is designed with a conservative cooling strategy. This is generally positive for longevity but can be inconvenient due to the noise.Fan Design: The loudness may be attributed to the fan's design, speed, or wear over time. Some users have reported success in reducing noise by upgrading to quieter fans or installing fan speed controllers, though such modifications may void warranties or affect cooling efficiency.Installation Location: Placing the inverter in a well-ventilated, less frequented area can help mitigate the impact of fan noise on daily life.This inverter is a solid performer in terms of power delivery and reliability. However, the frequent and loud operation of its cooling fan is a significant drawback for users sensitive to noise. For those prioritizing quiet operation, it may be worth considering alternative models with advanced thermal management or quieter fan designs, or installing the unit in a location where noise is less of a concern
