Renogy Inverter P2 3000W Pure Sine Wave Inverter 12V DC to 120V AC Converter for Home, RV, Truck, Camping, Trailer, with Wired Remote Controller, Support Li, AGM, SLD, GEL, FLD Batteries

Preface: I'm using this in a boat which is acceptable but not ideal. It has to do with the way the neutral and ground are connected. However, this is more of an issue with combo interval/charger units, and since this is strictly an inverter that gets turned off when we're finished with it, that makes it acceptable. Please consult a qualified marine electrician. Product evaluation: We are very happy with this inverter. The instructions are clear and it works as described. We have purposely purchased appliances that are lower wattage so that it can run 2-3 of them at once. As a test, I used it to heat a tank of water on the boat and it did the job. If the batteries dip below about 11.5 volts, it will keep working but start beeping. As you may know, flooded batteries (which we have) can drop down to 11.5 volts for a short period without harming them. Once the load is taken off, they generally "recover" to well over 12 volts. While the inverter comes with a wired remote on-off switch, we do not use it. As should always be installed, we have a rotary inverter power cut-off switch between the battery bank and the inverter. We simply leave the power switch on the inverter housing in the on position, then use the rotary switch to turn it on and off. We also installed a 250amp fuse between the battery and the rotory switch. Do not use the inverter without a proper fuse. The inverter comes with 2 battery cables but they were not adequate gauge for our application. There are tables online that will tell you for a given load and length of wire run what gauge you need. Do not gloss over these details. The wires being included could lead you to believe they are all that's needed to connect the inverter to the battery, but that would leave out the fuse and cut-off switch. We have now been using the inverter for a couple of months with zero issues. Because we have it installed where we can't easily see it, we like the short beep that it makes when we power it up. It gives a similar but longer beep when powered down. No negatives to report.

I bought this through "Amazon.com Services, Inc" at a discount hoping to save a little money. It was labeled used like new.I used proper battery configuration, 4 LPro 100amp battery is parallel configuration and only got a beep sound. Proper wiring and fuses. This is my second bad experience with Amazon.com Services, Inc on used like new electronics.Returned and got full refund.......Hope this helps anyone!!Update: Bought a new one and is now installed working well. We ran our AC for about 30 minutes as a test and it pulled 31 amps we added the Freg. and it still worked then added the microwave and it stopped. I hardwired the inverter. The plugins only allow for 15ish amps

Sine wave quality:The product is small enough to fit into the compartment that I want to live in. Also, enough power to run the Ninja blender. I also like the Renogy products.

Why did you pick this product vs others?:Because the previous product had failed.Power consumption:ExcellentSine wave quality:ExcellentPower source:Don't knowWorks well:Above and beyond expectation

Worthless, tech support horrible, under warranty but will not replace/refund.Let me explain further…I purchased this inverter for an off-grid Solar charged battery bank to run my Starlink and wifi camera, along with a 7k btu window unit. This setup is located in the Atchafalaya Basin, Louisiana (think the TV show “swamp people” that’s where this camp is) in the “middle of nowhere”.The battery bank consists of (8) 100ah 12v Flooded Lead Acid batteries wired in parallel for a useable 400ah bank. Batteries are wired together properly with 2/0 gauge jumpers and connected to the inverter with 3’ 2/0 gauge pure copper cables.Battery bank is charged/maintained by two Renogy charge controllers (1) 40amp MPPT with (4) 100w panels connected 2x2 (2-200watt strings).The second Renogy Charge controller is a 60amp MPPT with 3x1 240 watt solar panels.Plenty of power for what I want, and yes I know I could get more with a 24v system… but I went with Renogy 12v… big Mistake!!Everything worked fine for about two months. The Starlink was on, camera working, and I was able to turn the Wifi AC window unit on during the day to dehumidify the camp.Then one morning everything turned off, which required a trip down and 30 minute boat ride to investigate. The yellow GFCI light was on. So I wired the AC unit to the load terminals that supposedly provide more power, flipped the switch back to on, tested (and it worked) and returned home.Next day it happened again. So I called Amazon (who was the most helpful during this fiasco). Amazon directed me to Renogy because I was outside the 30 day return window.Renogy advised I needed to ground the inverter and use 4/0 wires to the 3000watt inverter. Note there isn’t anything in the instructions that specify what cables are required/recommend.So I make the long haul again with 10AWG stranded insulated copper wire, 8 gauge pure copper wire, an 8’ grounding rod, and brass grounding connectors.I sink the rod about 20’ in the mud, run the 8awg solid copper wire into the camp, and ground the inverter using the recommended 10AWG insulated stranded copper wire.I make the connection to the inverter using 2’ 4/0 pure copper cables, test, (it works!), and I return home.Next day everything shuts down again. I called Amazon who put me though to Asurion (I bought the insurance), who routed me back to Renogy because it was still under manufacture warranty. Renogy asked if I had performed any multimeter tests, which I had for my own curiosity (not directed to do so by Renogy) and so I reported my test results… 13.8 v DC no load, 120 v AC no load. Renogy said they needed picture evidence. I asked if I they could save me another trip down and allow me to return/replace the inverter, and they said no, no, no. I asked several times because I felt they just kept making things up for me to-do and not honor their warranty.They said I could return it (but wouldn’t allow me to do so) and they could test it, and if they found nothing wrong they would charge me for testing and shipping. At this point I really don’t trust them to “test” the inverter and accept that there’s something wrong with it. I tell them they need to honor their warranty, they direct me back to Amazon.PLEASE DO NOT BUY THIS INVERTER!!!Save your TIME and MONEY and buy another brand!!

This product works good as intended. I just wish everything to plug in wood be on either the front or back but not both. If all the chords are on the front, the fans could be in the back.

Quality product. Quiet and efficient. Used it in my boat's solar setup and it very much did what it needed to do. It's larger than I thought it would be, but not too large. And perhaps that's one of the reasons it stays so cool and quiet. Very happy, and would purchase again.

It works great on our first camping trip.Hoping to have many more years of use out of it and there solar panels. I have the two hundred watt portable panels and I just brought the two hundred watt set for the roof of our 5th wheel.
