  • Excellent inverter!
Size: 800W12V
Finally an inverter that fits my needs! The fan is temperature controlled and shuts off completely when not needed. I have no use for usb ports, which it has none. True pure sine wave AC. This is a great addition for my DIY 100a battery box. Well constructed, aluminum case, good heat dissipation, power output as specified. Decent 7awg M8 cables are included. ... show more

  • Very good tech support.
Size: 3500W 24V
My 3500W 24V inverter failed, no AC power, contacted [email protected] by Email. This started a series of Emails everyday, checking, testing, comments back and forth. To make a long story short the Service Dept. and Tech team decided to send me a new inverter. Problem solved, the new inverter works great. The Service Dept. and Tech team were very through and reasonable timely. I will stay with Reliable Inverters because of there reliable Service Dept. I will buy again in future. They rate 5 stars.

  • Hard wire terminals are not labeled!!
Size: 3000W24V
So far I enjoy the experience with this Inverter. After a quick test with a heat gun and the receptical, I hard wired it into my RV, and some Lifepo4 batteries. Has a switch that is easily used from many feet over from a wall. I can now run everything in my RV simultaneously, Even the Microwave is powered more evenly than it did when on generator power. Although I will note I had to take the Inverter apart to see which terminal was Live, Neutral, and Ground. As unfortunately they are not displayed on the exterior of the unit, or inbthe manual.... So if you are not familiar with electrical, and want to hard wire this device. Definitely make sure you understand what you're getting yourself into with this Inverter. I can here the fan from the other side of the RV every once in awhile while watching TV. It's definitely more quiet than a Generator could ever be, but definitely noticeable, much like a desktop pc fan when under heavy use/ gaming ect. The unit is lightweight much like other cheap Inverter, as for durability, that is to be determined, this review will change according. I would have given this unit 5 stars, except the failed labeling of very important terminals. I would hope future versions will not have that issue. ... show more

  • Very reliable Power Inverter, almost 4 years and not a single issue.
Size: 5000W 24V
I bought my very first Power Inverter from this Brand back in June 2019 and it has been working great ever since. And now that I needed to expand my system I went back looking for the same brand, besides the reasonable price is very easy to install and very good and fast customer service.

  • line terminals insufficient for 5000 watts at 120 vac
Size: 5000W 24V
speaking as a degreed EE, the external line terminals are not adequate for 5000 watts at 120 Vac. by Code, at 41 amps, the line terminals as well as the terminal block should be designed for at least a #6 AWG copper conductor... they are NOT. this is unsafe as if the consumer uses a smaller gauge wire, a over temperature situation will occur at the line terminal block at full load. overheating can cause a fire hazard. it should be redesigned ... show more
