Renogy Inverter PUH, 2000W Pure Sine Wave Power Inverter with UPS Transfer Switch & Bluetooth, 12V DC to 120V AC Converter for RV, Truck, Home,Camping - 4000W Surge Power, Remote Monitoring

This inverter may be okay for simple RV or camping use — but if you're running ANYTHING mission-critical, stay away. We installed this Renogy 2000W pure sine inverter to power a VHF/UHF repeater site supporting emergency communications across rural Colorado. Despite perfect grounding, filtered AC lines, and a robust battery bank, this inverter began triggering false key-ups on our repeater — a potentially dangerous and unacceptable behavior. After exhaustive troubleshooting, it became clear: The inverter's internal transfer switch or AC circuitry is injecting noise or voltage spikes into the line — triggering receivers and falsely activating transmitters, even with controller logic turned off. Even worse: ✔️ No alarms or faults triggered ✔️ Battery levels nominal ✔️ Repeater receivers locked into "active" state ONLY when inverter AC was present ✔️ Issue resolved immediately when the inverter was disconnected We have extensive documentation, SDR audio recordings, and logs proving this — and this is the SECOND Renogy inverter with identical issues. Their support team plays the "stall game," asking for redundant info and now demanding product compatibility research for a clearly self-induced issue. We were ultimately forced to disconnect AC from the inverter and invest in an expensive Victron charger to maintain battery health — a workaround that shouldn't have been necessary. This is not a safe product for any critical communication or backup system. If you're running an off-grid repeater, surveillance node, emergency shed, or any public safety system, do not use Renogy inverters.

Works as advertised I did buy used like new but had damage to exterior from poor packaging and delivery kind of wish I bought new but does function properly.

The unit never worked. When unit was off, the unit still sent power to the RV power panel. Also, in pass through mode it isn’t sending full 120 volts to panel. I opted to get a refund. It was going to take weeks to send unit back to Renogy for testing. I ended up going with an inverter charger from victron and it is rock solid. It’s more expensive, but it’s the best. The tech told me they see all sorts of issues with these Renogy inverters. I lost $1k on install and testing costs on this unit. Oh well.

You know Plug ins are picky about their power sources, and this 2000w pure sine wave holds up and charges my Plugin Prius along with a renogy 30a charge controller. Wish I could afford renogy batteries. I have 200w flex solar on the roof, and can keep myself charging on the go without having to plug in at home and increasing my SCE bill. It will take a bit to break even on this, but setting this up in a crate, using quick connectors, I also have a portable power station I can use anywhere that beats the pants off of any off the shelf product. I have a lot of Renogy products, and they are some of the best out there, I have 10 panels, 7 controllers, in a lot of odd setups, Suburban, 2 prius, Camping trailer, they knock it out of the park.

Not reliable enough for continuous backup for an oxygen concentrator. Good for non-critical uses like camping but don’t buy if you need serious reliable backup power. I bought this and 2 large batteries to be a backup for an oxygen concentrator for my elderly mother-in-law so that when she’s home alone she’ll have backup power when wall power goes out. Issue 1) After 3 months of continuous use, it just stopped working in the middle of the night. The manufacturer was good about quickly replacing it. But the fact that it failed all by itself is an issue. Issue 2) About half the time that wall power fails, the inverter fails to switch over to battery fast enough to keep the concentrator running and so the concentrator stops running. It switches over in about 50-60 milliseconds but isn’t fast enough. I had to buy an additional UPS (different brand) that switches over in 6 milliseconds so that the concentrator wouldn’t stop. Issue 3) It’s difficult to wire in the wall power cable to it. And the wiring diagram is confusing. It shows putting the wires in a rectangular hole when it actually should be wired into the round hole. They should make this easier and mistake-proof by them installing a male socket just like what’s used for computers. See my picture. Issue 4) The terminal insulator covers are poorly designed. They don’t fit right and don’t cover the connectors much. I had to modify mine to make them safely protect against accidental contact.

Contrary to one of the images above which says "On-Grid Backup Power Solution" "Continuously power up your batteries", this does not offer the option to charge your batteries. Instead, even when connected to the grid, it drains them by 1 - 10 watts. You will need a separate charger running to maintain your batteries. The inverter will not work at all without a battery connected. If you want to disconnect the batteries for any reason, you will need to shut everything down first. We bought this to replace a regular UPS after the batteries failed on it for a second time. There are several computers hooked up to give us time to shut them down safely in a power outage. We tested the transfer switch by disconnecting the grid power, and it was able to switch quickly enough to keep the computers running. We also have a sound system connected, which did not stay running during the switchover. We only tested once so far, as we don't want to stress the systems. The Bluetooth is something that could use improving. There is no switch to turn it on or off, so it is always draining power. We did not like the look of the mobile app, but did find a Python library for connecting to Renogy BT modules which we tried. It was able to read basic info from the unit, sometimes. When reading it would sometimes timeout, and then it usually needed over a minute before trying again returned data. If trying to read too many times in a short period, such as 2-3 times per minute for a few minutes, the BT simply shut off and would not return until the inverter was turned off and back on again. It is possible the library we used caused these issues and the app would do better. We were not interested in the BT functionality, so this is not a big deal for us. Ideally we'd like the option to simply turn the BT off when we aren't using it. We are using a separate power monitor for the batteries. Overall, this should work for our needs, though not nearly as well as we expected from the listing. We did debate returning it, but had already cut the included wires and mounted it. In the future we'd go with a different solution.

Tried using a brand new purpose bought extension cord to wire the in and out connections. Tried stranded knowing it likely wouldn't work. Crimped ferrules on, still won't grab the wire. Will try it with a piece of romex when I get around to my scrap bin, but not holding my breath that the springs will hold considering it wouldn't hold ferrules with indents.

I received an electrical shock when I touched the DC battery connection terminals. (no AC in connected) Measured 108 V AC True RMS on both the + and - inputs to chassis gnd. An oscilloscope verified there are big spikes on the DC terminals when the inverter is running. The AC Line connection terminals are very difficult to use. Instead of screw terminals, you have to push a very small flat blade screwdriver into a slot while at the same time pushing the wire into an adjacent hole. AC pass through HAS to have battery connected AND inverter mode on to have AC out. The no load idle inverter input power is 26W, 150% of their spec (my Zetawale 2500W DC in idle is 8W, and AC pass through does NOT need battery connected.) UPDATE 2026-01-29: after going through Renogy support run around, they eventually acknowledge that this high voltage AC on the low voltage DC input is not an individual failure, but how this line of inverters is designed. I have an older Renogy 1000W inverter, a 600W Eco-Worthy inverter/transfer sw, and a 2500W Zetawale inverter/transfer switch, and all of these have no more than single digit AC noise on the DC inputs. So no, this Renogy design is not normal. In addition to the physical shock, high voltage AC spike on the battery might damage an LFP battery BMS.

no lo pude usar no me sirve este equipo pues es de la mitad de la capacidad del equipo comprado llego uno de solo 1000W y compre uno de 2000W No puedo creer este error me frenó el equipamiento de mi RV y es básico este equipo, suspendido mi viaje una empresa como RENOGY debe responder Enviando el equipo comprado
