## Description

About WZRELB: Professional manufacturer for pure sine wave power inverter for 10 years, provide prompt reply, friendly customer service and 12-month . Product details: DC input: 12V DC input range: 10V-15V Efficiency: 85%-90%AC output: 120vFrequency: 60HzSocket: Dual US typeLow Voltage Alarm: 9. 5V-10. 5VLow Voltage Shut Down: 9V-10VOver Load: shut off, recover manuallyOver Voltage Shut Down: 15. 5V Cooling Ways: Cooling Fan will run when the temp is over 50 degree Celsius Precautions: 1. Please do not connect the inverter with the grid power, and a reverse connection of positive and negative is also forbidden. 2. Please do not overload. If your applications are inductive loads, please choose the inverters whose continuous power is 3-7 times higher than the watts of your appliances. If you want to power up a refrigerator, we suggest you use 10 times higher power inverter. 3. Please turn off the load first then turn off the inverter. And as there is a soft start function, please turn on the inverter first then turn on your loads, or the output may not stable at the first seconds. 4. For a red light flashing, it remind that the input voltage is a bit high. 5. Please use the set of standard battery cables we sent, or a full output may not be . There are build-in fuse for safety concern, the fuse come with package are just spare parts. 6. Considering transportation safety, we took off the battery of remote controller, you can buy it in your local place. Its specification is 23a 12v.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent  product
*by M***R on May 28, 2025*

Excellent product, works great…..,

### ⭐⭐⭐⭐⭐ Well made and has all the right protection on it.
*by J***E on January 7, 2025*

I purchased the 800W version of this (They make many sizes). I intend to use it to backup my furnace during the winter if a power shortage should occur. I have a Backup sump pump with a marine battery with an estimated 135 amp hours. The sump pump backup system keeps this battery fully charged all the time. My furnace draw about 280 watts once it starts. The inverter can deliver 800 watts constant and handle a surge of 1600 watts. It should be able to run my furnace for about 4- 5 hours continuous, but my furnace typically only runs about 40% of the time so most likely it should keep me going for about one day on my battery This unit is great because if my battery supply drops below a certain voltage the unit shuts down so It would produce a low voltage output. I have not yet had the need to run it So I won't know if it works as planned until the power goes out. I will update if that happens.The unit delivers a solid 120.0 volt output which i verified with a "Killawatt" power monitor and a voltmeter. The unit appears to be well made, and has a rugged metal case that can be safely mounted if need be.

### ⭐ Display broken, poor quality control, stopped working within 24 hours!
*by A***8 on March 26, 2021*

Update (3/27/21): After less than 24 hours, this is now broken. With a 115W load, measured with an energy meter at the output, the unit will shutdown, and the AC voltage goes out (the DC voltage is still illuminated), the RED fault light is not illuminated. Sending this back as defective. Opened to inspect for damage, and found some black specks near a resistor, and some odd marks on the top edge of the largest black capacitor. Not certain either is the cause of failure, but very much indicative of poor manufacturing processes and lack of quality control inspections. Also added a short video of the fan running, pretty loud.Summary: This is a 24 volt inverter, 300 watt. Previously reviewed the 6000W model from the same company. I also have a 2000W inverter, but the overnight power draw to supply a small 15W (120VAC) was quickly draining my solar/PV battery bank. I ordered this 300W to use instead.Observations: First issue right out of the box is that the DC voltage does not display correctly. The display should be "26.0"; however, the upper-right LED bar is broken. Second issue is that in the bag of washers, one of the six was rusted. Third and final issue is the DC power cables. For DC power cables, having a good connection is important for efficiency and safety. Doing a pull test on the RED/BLACK cables revealed that the power cables are crimped poorly, and not soldered, which results in the terminal lug pulling right off (same issue with the cables from the 6000W unit).Recommendations: Check the DC power cables for loose crimping on the lugs. Solder them for extra assurance.Pros: None.Cons: As listed above.Conclusion: At $62, rating this 1-star, and not recommended based on numerous quality issues, especially the broken display.Related Products:WZRELB 6000W 24V 120V Pure Sine Wave Power Inverter with 4 AC Outlets Wired Remote Control (RBH-S600024WR) ~ $1000https://www.amazon.com/gp/product/B08216ZMHW
