2500W 120/240V Split Phase Pure Sine Wave Off-Grid 5000W Peak Inverter 48V DC to AC Output for Solar Systems

Good design, simple to set up, has many features to protect unit from user error, really like the battery voltage information on input side. This unit is used to power barn lights, but is also used periodically to power a water pump, battery charger, radio, a chop saw, and tool battery charger. It was even used to power a travel trailer recently while visiting the farm.Pleased with the product so far, a couple weeks in, and if it has the durability to last for many, many years, performing flawlessly, then it will have earned its keep.This unit enabled me to upgrade from a turbine 12VDC system to a solar 120VAC system and thereby put a lot of unused electrical energy to use across multiple applications.This unit completed my solar/battery/inverter off-grid electrical system.

Certainly the downside of mail order. After sitting the box for 3 weeks, working fine for 2 weeks (carrying resistive loads of up to 700 amps), It failed 1 week past Amazons 30 day return (Oh, that old story) and crickets from the seller and manufacturer. The reviews that refer to this unit as over rated amperage are correct. It was not even putting out 2000 watts when it died.Update: After the unit died I immediatley emailed the seller and the manufacturer. In all fairness, I did not know it was a holiday in China. Not to mention, it seems the world has come to a screeching halt. After waiting a day, I decided to call the manufacturer. Shirley and Qiana have been very pleasant, helpful and well spoken. We are currently working through the expected Q and A and its clear that I will be taken care of. This is not the place for the review of the seller but I had mentioned that I had heard nothing from the seller in this review. I was really happy with this inverter until it died. I was testing appliances one at a time. A 1.5 hour front loader washing machine load was fine. The inverter stopped working during the 2010 Built in Whirlpool dish washer cycle. Both the clothes washer and the dishwasher draw up to about 1100 watts measured with a real time utility meter. One would think that those would be safe with an inverter nominal rating of 3000/6000 watts. The fine print says inductive loads (electric motors) should be calculated at 2-7 times the rated value. Quick math says 1100 watts should be 2200-7700 watt inverter. The part that bothers me and the one star rating is the fact that the fuses did not blow. There are 8 - 20 amp internal fuses that are not easy to get to but you would think would protect the unit. They dont and they are not small sparks. It sounded like someone was welding. A little scary. My advice, for what its worth, make sure to get something that clearly states "protected". And, dont leave it sitting in the box for too long before you install it.Update 2: Amazing customer service from China! I have updated from my one star review to five stars because Reliable stands firmly behind their products and customer satifaction. I have purchased the same Reliable brand and yes, larger, 7000 watt. I was completely and happily made whole for my first purchase through its warranty. When it comes to hard wired house solutions you cannot be too careful. I was connecting circuits to a solar sub panel connected to the inverter with 8ga wire through one 20 amp breaker. 120v x 20a = 2400w and testing one appliance at a time. I thought that I was safe with a 3000/6000W inverter. I would love to see a video review of intentionally driving every inverter above its nominal limit to see what it does before i purchased it. That would be comforting, at any time we could 'inadvertently' ask too much of our electrical system.

I've only started really testing/using the inverter, but have been pleased so far. Current application is a portable battery power unit, meant to run heavy short duration loads where power is not available and smaller battery powered devices are not enough to manage. Its powered off of a 24V 40Ah (150a continuous) battery pack - so while the inverter is capable of running large loads, the pack depletes before it could really be pushed for long hours. Its able to handle a toaster oven for ~30 min of cycling and a 1500 watt water kettle for 15 minutes of continuous heating (separately) without any issues.Given how its worked so far, I would comfortably plug any item that would normally go on a 110V 15A house circuit to this for general use. The fans do run constantly at a low setting when the unit is powered on, and I have only had them go into a loud turbo mode once with the kettle. That said, the unit remained relatively cool to the touch with no noticeable hotspots forming and went back to a quite mode after about 1 minute of no load.Tracking loads at the battery and device, I have seen anywhere between 85% and 93% efficiency. It does put out 120V on a full charge pack, but has dipped to ~110V during heavy draw applications (1500 watts). Idle draw is ~0.6-0.9A on the battery.I don't have the equipment to test how 'pure' of a sine wave is formed, however I did run the microwave off of it and noticed that the unit was a touch quieter while cooking (pulled 1500watts/12.75A at plug and 60A/27.5v at battery) . While not very scientific, the fact that it ran well points to something being right. Still expect inefficiency and do your own testing if before trusting any sensitive equipment to any inverter, this one included.The one thing I now wish it had was a remote on/off switch - but that's not anything against the unit, just something to consider if you are stowing it away somewhere. Cables are also not exactly the definition of high quality, but do the job nicely and have not gotten hot. If you are doing large loads for long periods, wires would be the first place I would be watching for heat and replace - after that just be careful of what is around the exhaust/intake ports so that you don't get anything too hot from it running.Great little unit for the price!2000W/4000W 24V system

This inverter has performed well for me so far. Easy installation. No frills, so I didn't pay for a bunch of features I'm not going to use. I think the manual could provide a bit more detail and clarity, especially in terms of grounding, but it gets the job done, and their tech support does seem reasonably responsive.Under a 1000W load, the fan will come on and off intermittently. The fan volume is pretty typical as compared with other AC Inverters I have worked with. Puts out 120V under load, which is nice. A couple other inverters I've used only manage 110V. Definitely recommend it.

Received in brand new condition, ($279.99 + tax) hooked up and ran a microwave and a 5000 btu air conditioner without any problem. The testing was brief but so far im very happy. Unit did not get hot or even warm . I will update as usage is normalized/ increased.Update Sept. 2020:Still very happy with this purchase. If i had to do again i think i would have gotten the remote switch, 24 volt version but at the time i only had one 12v battery. However, this unit is running great off of 2 parallel ,100ah lithium batteries. The use of the 1500 watt microwave was limited to a low power setting after installing a 100 amp shunt and meter on the battery bank. Replaced the microwave with a smaller 700 watt. No complaints.Update May 2023 : This unit lasted 3yrs and 10 months after regular daily light duty, (45 - 200 watts and 700 watts daily during the last 2 months). It got so hot it melted and dripped solder. I think one or both fans may have failed. No warning prior to the overheating meltdown. Luckily I noticed the power loss immediately. This is a disappointment in the quality of the build. I would not buy this unit again. It never could handle anywhere near 2500 watts. A heater or a two burner cook top would trip the inverter well below 2500 watts.

I was told it would arrive in about 2 weeks. Instead it arrived in 3 days. This is for my RV so my wife can run her 1800 watt hair dryer when we are camping off grid.Some confusion arose, as instructions weren't very clear ... it arrived with a bag full of 40 amp fuses, and no explanation. I assumed it needed to be fused (like any electrical appliance) and I was to use the 40 amp fuses provided. My setup wouldn't work with these, so I used another 40 amp fuse set up and it continually blew the fuses. I emailed the manufacturer, thru Amazon, and asked what's going on. Hats off to the manufacturer...they responded within a couple of hours and said it doesn't need additional fusing, and the 40 amp fuse was way too small. I needed about a 200 amp fuse. I asked why they provided all of those 40 amp fuses, and they responded, again in just a couple of hours, the inverter has several 40 amp fuses internally providing all of the protection it needs. Those extra fuses are in case any of those blow. Now it works perfec6.

I bought the unit but a number of delays got in the way to installing it. It was in the original box until today. I installed it. Triple checked everything. The display for input looks good. But there's no output, and no display for output. I checked all of the fuses and all look good. Apparently these units aren't tested well at the factory. $300 down the drain.Update: seller went above and beyond with resolving the issue. Replacement worked fine.

I connected it with jumper cables to my car battery and drove 5-hrs with lots of water heaters and pumps running the whole time. No problems at all. Just watch out the terminals on the front and back of the inverter are "live" and will shock you if you touch them. Great product though!
