WZRELB Power Inverter 2500W 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 gave this a thorough test and determined it produces very clean sine wave power (using my digital oscilloscope). It will run happily putting out the max rated power but it does get warm so be sure to allow some cooling air around the unit. The cables provided with unit (which are really a plus since I didn't expect to see cables included with this) are too thin for sustained us at max power. It's nice that they were included so the unit could immediately be used but people should understand that they shouldn't be used for more than 50% power for any length of time. (my unit is rated at 2500 watts continuous power) . I am currently using2 gauge cables for my application which will draw 1,800 watts max sustained power. These cables are not cheap and I understand that it wouldn't make sense to include to these type of cables with each unit.

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

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.

The unit as received had one out of two output plugs dead.Contacted the manufacturer and they asked me to open the unit and check for bas soldering.This I did and indeed... the quality of workmanship was unacceptable.It looked like they had run out of the correct connecter then was designed for the circuit board and the replacement did not fit. The leads were bent and the board was barely and not connected to the power leads that supply all the voltage and current. This is a hazard and asking for overheating at the connecting points.As an electronics technician, I am comfortable with pulling the circuit board and cutting, reshaping and trimming the connector in order to get the board to fit the connector and rewiring the connections with a heavier gauge wire and connectors. The inverter now works well and I'm no longer concerned with a fire hazard or danger of failure concerning the particular section of the unit. I will monitor it closely in case any other part of the unit suffers from the same deficiencies in quality.
