Finally an inverter that runs my full shop including my 120v. mig welder, I've tried 2 other inverters that were modified sine wave prior to this but this is the only one that runs my welder because is pure sine. I'm very happy with this purchase and looking forward to see of it last. The only thing that I don't like is that the fans are loud and they come up every 5 minutes and last 30 seconds on, but I guess that's good for not keeping the inveter hot but is a little annoying if you are in a close environment.

I didn't like the output terminals close to the bottom. It causes cable kinking when mounting the unit. Additionally I had to purchase some terminal adapters to accommodate the setup. I didn't care for the inverter showing incorrect voltage while on. My batteries are often different. This I'm assuming to be after drain voltage.

Otherwise this inverter has been serving me well. It powers a rooftop 15k btu without issues. I am just now getting to the point of bigger batteries but for what it's worth this worked on 3 SLA 12v deep cycle batteries for a over a solid year now. July 14th 2022

Tested the 5000w inveter to run a 3/4 hp motor but it would reset the inverter for a few seconds then reboot the inverter causing the voltage to increase from zero to 50v then 120v. That is not good to start any electronics from zero then to 120v full voltage. The inverter should run full 120v before an electronic device is plugged in, but because the inverter resets and then reboots, it puts the device to draw from zero then gradually to 120v. The inverter did continue to run afterwards though, and did continue to run the motor. It was odd that the inverter would hum a little when the motor was running. My EDECOA pure sine wave 3500w inverter did not do this at all and started and ran the motor perfectly, without humming. Maybe this WZRELB brand's load circuit is too sensitive. Before, I had tried this brand's 3000w inverter and it was not even able to start the motor. Based on my experience with this brand, I would not recommend buying it, or buy their much much much much higher wattage rating than what you think you would need; however, you will then have to deal with their higher standby current draw. It seems another reviewer had the same problem when he "opened his refrigerator." However, the manufacturer was very responsive in their communications so I will add one star to the review.

Pretty simple inverter, but works as intended! Runs all kinds of stuff, water pump, microwave, a/c.

Bought this not so much for the 5000W continuous rating but to be able to start up motor loads like washer, gas dryer, large refirigerator, air compressor, portable a/c unit....and it works perfectly. I can even run washer and gas dryer at the same time. Have been using it a few months now with no complaints. Couple minor issues...the unit came with two sets of 18inch 16mm2 connecting cables but user manual recommends three sets....also the ac voltage amplitude fluctuates +- 2volts when washer is running....I contacted Reliable and they sent me a third set of cables free of charge and said voltage fluctuation is normal....so I am very happy with the unit so far! Word of caution...to start large motor loads, the extra battery cable and large battery bank are necessary to prevent excessive DC input voltage drop due to large initial surge current on the DC side. If running battery cables more than 18 inches from battery bank, a properly sized cable set would be needed for proper performance.
