WZRELB Full Power Endurable 3500W 12VDC to 120VAC 60HZ US DUAL OUTLETS LED DISPLAY PURE SINE WAVE INVERTER Power Converter, (RBP350012B1)

Didnt work came fried manufacturer sending a new one to try. The new one was bad too this makes 2 bad units in a row. Do not buy these they are junk. Very bad units made cheap and not very well .the manufacturer suggested to open the second unit and check fuses i found small metal shards inside unit like stems from soldered parts. Fuses are fine . They asked me to test some components all passed. Spent 175.00 had electronics repair guy look at it he said the AC side control card was no good in posted a pic of it.the first unit was fried pit of box this one had bad no working part on board. They told me to buy a new battery bank and new cables that my system is the problem that they make highest quality units that my system must be wrong. I hooked this up where my existing American made unit was installed . 4/0 cables .1410 ah 12v bank after this unit failed to work unhooked my good one back up and was back in buisness . The new card was sent from manufacturer. I spent hours uninstalling the bad card from board and installed new card carefully soldering it. The unit now powered on and runs havent tested on larger load. Another thing was i was charged 2 times for the units the refunded it once then said they sent 2 by mistake and didnt and recharged me again. And i spent 175.00 to get it bench tested and did a repair to the actual 2nd unit china sent me and still ate the repair cost and plus amazon charged me for 2 units and i only have 1 unit that i repaired at my own expense . Rip off total junk . I am very angry about it.

I got it really cheap so I figured they may have upgraded the design or something, it was a return, etc. so let’s try another. I got the 3500w unit this time, hoping it would be able to power my air conditioner plus fridge, etc. in case I needed it to. This one had a really weird pulsing output, so my fridge light would blink. When the fridge motor turned on the problem was so bad it would cause pulsing on the 12v side so my DC lights would pulse too, I’m assuming from the load changing so much. So I returned that one and figured I’ll try one more just in case that was just defective. I believe it is, because the new one was much better. The DC side was fine all of the time but the fridge light still pulsed. Ultimately I found that I could make the pulsing stop by adding a lot of load, but under light load under 500w there’s no way this thing has a normal output. I was afraid my things were gonna fail early because of bad power. Replacing it with an old, broken xantrex unit I had laying around but finally fixed solved all of my problems. I also emailed the company via their website for troubleshooting ideas or verification but I got no response. A person on a forum I frequent said that a 60w incandescent bulb was fine on his 24v unit, but not on this one (3500w 12v). I don’t know if it’s a bad batch or a bad design but I’m done with wzrelb unfortunately.

It doesn't quite have the start up i was hoping for but over all a dependable unit. Takes strong batteries and enough of them to power it. Fans are pretty loud but they don't stay on long unless your more than 600 watts. The led readout is correct. Used a 12 amp skill saw with no problem but thats it on the start up at that current. Seams to have clean output and all my appliances are quiet and run cool.

I don't understand why a 3500 watt inverter won't run a 15 amp miter saw. The saw only requires 1800 watts to start but it won't even spin up. After a few pulls of the saw trigger shuts off the ac side of this inverter. Would like to hear how my simple math isn't adding up.

I dislike the 40 amp fuses replaced all with 10/15 combo fuses because i want the fuses to break before the mosfets havent blow a fuse yet my breaker went off from battery its a 32amp so dont understand the 40s that come stock when my 10s seem ok

It works great hope it lasts

Hooked up this unit a month ago, whenever the output exceeds 850 watts it shuts down. Useless piece of gear.
