WZRELB RBP300012 3000W 12V 110~120V Pure Sine Wave Solar Power Inverter DC to AC System

3000w inverter works well, although I've only tested it to 700w. First photo is just initial connections and testing, I plan to build a more portable box setup with the battery.I was concerned using 280Ah LiFePO4 battery with 13.2V (resting voltage) that the output AC voltage would be high as reported by other reviewers. However, it's stable at around 124VAC. I powered a color laser printer and PC with it to initially test, and seemed to hold fine peaking to 700w. I have it hooked up to a bluetooth "SmartShunt" that lets me monitor voltage and draw status (second photo is of usage stats with all network, subwoofer, and PC hooked up), and it idles with no-load at 0.54A (7 watts). When I turn it off, it does *not* draw any power, contrary to what I have read in other reviews. The built-in voltmeter is about 0.2V less than what the SmartShunt app says: So at the shunt it's currently 12.89V, whereas the voltmeter reads 12.7V.I like the form factor, it's smaller than competing 3000w inverters, although it is still fairly large. Just think of a tall dictionary, or a half-height shoe box.I got this for an offgrid/emergency backup power setup. I sized it to 3000w for any potential surges from air compressor or fridge use. But in reality I'll probably use it for less than 300w continuous in outage or field situations. As I was typing this, the fans turned on for a minute. They are noisy, similar in volume to a hair dryer on "low" setting.Overall, this seems to be a great value for the money where other name brand inverters can be 2-3x as expensive. It is well reviewed elsewhere on the internet, so that's why I decided to give it a try.

I used this inverter for my RV .it works very well with my system.

As other Reviewers have mentioned, if you get a good unit, it seems to work, but for how long? If you get a bad unit, just return it. Dealing with WZRELB is maddening. Even if you write in detail about what happened, what you did, what your battery state of charge was, etc., they reply back (3-4 days later) and ask you questions that were already provided in your initial message. Or ask questions that make no sense. With the unit I received, once the inverter was turned on, I plugged in the refrigerator & turned it on. The inverter, immediately, tripped. Like, immediately. I told them that. Their reply was:"Thanks for your update , I noticed that the order amount is 215.42usd, generally the price of this inverter is around 300usd, is the condition of this inverter used-like new ? Also ，could you please check if there is a DC voltage drop on inverter display when running the refrigerator?"Did they just imply that because the price I had paid for the unit was substantially lower that what they normally sell for...that it may be my fault for purchasing a "Used-Very Good" inverter instead of a "Used-Like New" or brand new unit? Hmmm, did they, or is it just me. And, how am I supposed to check for a DC voltage drop on the inverter display when the refrigerator never even started/ran? Guess I gotta have eyes in the back of my head to pull that off!That was "it" for me. I have no idea what the price of beans has to do with providing Support. If they can't read and/or understand an email written in English, one that explains-in detail-what happened, and ask ridiculous questions or questions that have already been provided, then as far as I'm concerned, they're just trying to prolong/draw out the process until you just give up & the Return window closes.Even though the 30-Day Return Window had closed, I was able to return the item for a full refund. I explained to Amazon's CSR the reason for the delay in using the product (I didn't try to use the inverter until I could afford to buy a larger Lithium battery the following month), and told them about WZRELB's failure to provide adequate support. So, just because the 30-Day return window has closed, call Amazon & explain. More often than not, they'll let you return the item with either a full refund or deduct a 15% "restocking fee", but at least you're not out a bunch of money. And, this goes for ANY item purchased on Amazon. Just so ya know.

This WZRELB 6000W 24V Pure Sine Wave Inverter,24 Volt DC to AC 120V 240V Split Phase Power Inverter is built with a very good quality construction and tight wire inlets/ outlet connections that hold the wires securely and safely. The LED screen on the unit shows a diagram of the outlet- power flow when turned on- either with the remote or the switch on the end of the inverter- and it is easy to see. This unit is being used in a dedicated function to supply power to a deep 220 volt- 3/4 HP water pump controlled by a pool pump timer and the inverter draws 24-volt DC power from 4- CR 430 AH- 6-volt batteries that are charged with 4- 100-watt solar panels and a charge controller to keep the batteries from overcharging. This inverter never overheats or with the surge rating- never trips and runs the pump smoothly and easily. Totally excellent inverter for this purpose and a very good find worth the price! Excellent find!

Works as intended. Cooling fans only run when needed vs all the time, good feature. Only grip would be you have to manually reset a low battery fault. It doesn't self reset when solar kicks in in the morning.

this product exceeding my expectations.

The media could not be loaded. I havent try many inverters but this is the 4th from this brand I have bought! 2 for my father and this is the second I get for me as an upgrade from 2000 to 3000 watts. Now the 2000 is for spare purposes, I use this inverters every single day, they are on all the time, I use the 2000 for 2 years and now this 3000 has begun. I bought it eyes closed, it make some noise with the fans since they are very powerful fans but I dont mind. Stays cool to slightly warm in heavy use. I used for power back up the house in a blackout situation and every day use in my kitchen with the dishwasher, toaster and airfryer.

At first look, solid. The test will be it's life usage. I'm still in the process of this project of building a power trailer. I will update with time. After all, it is in the electronic department.
