WZRELB RBP-500012S Pure Sine Wave 5000W (10000W Surge) 12V Power Inverter DC to AC Power - Solar, RV, Black

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.

I purchased the WZRELB RBP-500012S Pure Sine Wave 5000W inverter almost two years ago when I ordered a new van for a RV conversion. Unfortunately it took two years for the van to arrive.When I installed the inverter it would trip out when I tried to use a 900 watt microwave.The warranty ran out so I was out of luck. I built a spot and wired it for this unit so I figured I would just bite the bullet and ordered the same unit.It arrived and it is no better than the first one. I have worked as an electrician and built many RV's using inverters. I have more than enough battery bank with AGM batteries. The inverter would trip out with the battery voltage above 13 volts. It would stay on with lamps or other electrical loads as long as they stayed under 900 watts. So the unit is working and installed correctly, it just can't handle more than 900 watts. It comes with a package of fuses, if you have one of these I hope it never blows a fuse, it is almost impossible to replace them where they are located. Customer service is a China phone number. You might be lucky if you buy one but I think it's better to look at a different company.

Plenty of power to run our well pump. Nice remote screen to view input and output power. Instruction manual lacked information on the power button on remote screen and on/off toggle switch. If you use one or the other to power on the inverter, you need to use the same switch to power it off.I learned from experience on pure sine inverter, average multimeter does not work correctly. I purchased a multimeter with True RMS technology to test the 120v and 240v output.Very happy with this inverter!

The media could not be loaded.  This installation is in a remote outbuilding, the location makes running shore power impractical. I had previously been using an "inexpensive" 400/800w modified sine inverter to power my lights, but any load beyond small drill would make it go into fault mode and I'd be sitting in the dark, plus the led fixtures would flutter. The building is wired for a generator which works fine (and gives me an excuse to run it on a regular basis), but it's another step when all I need to do is make a quick cut. I found myself grabbing a hand saw at times as it was easier.This unit is installed using 1/0 cabling, a 400 amp fuse and cutoff switch (no draw unless I turn it on). The hard wire ports on the inverter are used to wire it directly into the breaker box as using the outlets on the inverter only supplies half the available power per outlet. As this building fully wired, powering it at the breaker box means all the outlets, inside and outside lights, etc. work. I'm able to use the 1/0 cable as I have very short runs (and equal length cables), if you have more distance between your battery bank and the inverter you'll want a larger gauge. The group 27 and 29 batteries are wired parallel with a solar panel to keep them topped off. If you're planning on extended use you'll want more batteries. There is no transfer switch so the "inverter" and "generator" breakers are mutually exclusive, having them both on at once would would end badly. Fortunately it's hard to accidentally roll the generator outside, start it and plug it in, practically idiot proof.The second picture show the idle draw for this unit, 2.37 amps/29.3 watts. For comparison the 400/800W modified sine unit has an idle load of .73 amps/9.2 watts. Basically 10X the power with only 3X the idle draw. I checked this using a battery meter sold here on Amazon which works great but only has a 100 amp shunt. For permanent installation a 500 amp shunt is needed, so in subsequent pictures (and under load) the meter is just measuring static voltage.I wasn't sure what would happen when I ran the big saws, I didn't try them before shooting the video so you're seeing the first attempt. What you can't see is my smile, at that point I was quite a few hours into the installation. The startup load on these big motors is several times the rated amp draw when they're running but the inverter didn't bat an eye. Pure sine also means cleaner power so even motors will generally run cooler, the benefits for more delicate electronics is already well known. I didn't try running both saws, but as a practical matter I don't work that way but did enjoy having the TV, lights, heater blower, stereo, etc. on while I was making the video which is pretty decadent!

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.

I didn't have the chance to connect it to the real thing, however, I tried it with different household artifacts at the same time and it seems to hold the voltage very stable. I connected a heat gun and a soup maker and it only dropped voltage by 0.2. I believe it's going to do very well for my off grid project. It feels robust.

The inverter could not handle big surges of power. I would run a saw and it would trip. My 1500 from Canadian tire is better

Got my father this upon request. Was told he slept head at the foot of bed, turned the TV upside down, paid customers what they owed him and went camping driving the entire time in reverse. Apparently legit product.

Goid Item, but would not work on boat as it does it does not have marine approvals or features

Manifestement pas assez fort.J'ai suffisamment de batteries pour faire fonctionner beaucoup d'appareils et cet onduleur ne fournit pas assez pour un petit micro onde!Il a même fait griller 2 fusibles 100 A!!!
