Renogy Inverter P2 2000W Pure Sine Wave Inverter 12V DC to 110V AC Converter, Off-Grid Solar Power Inverters for Vehicles, Truck, RV, Home, with Built-in 5V/2.1A USB/Hardwire Port, Remote Controller

I *also* own a Renogy 2kw combined charger/inverter. That unit has an internal 30A transfer switch and is very fast to change over. HOWEVER, it has two serious issues: 1) The fan is on a LOT even when just charging lightly and 2) it has to be "on" to charge the battery bank. So this, plus a separate converter-charger, means (1) you move the plug from shore power to inverter when you need to. Or does it? Well, maybe not, if you are willing to run the same way. The reason is this: This unit is SILENT except when under pretty heavy load. So if you have a converter/charger that can deliver the amps you could turn this on whenever you have shore or generator power, the converter is on, and your plugged-in things are on this all the time. This is basically 15 amps of output (as is the 2kw all-in-one) but the transfer is manual -- other than none at all if you leave it on all the time when on shore or generator power. Is this viable? IMHO, yes, because the quiescent draw on this thing is only about 1 amp or roughly 12 watts. You can't leave it on ALL the time when there is no charge as obviously 1 amp will kill your pack BUT if you have a charge source 1 amp is not much -- and you silent operation except under heavy load. If your converter/charger fan is thermostatically controlled.... there you go. The biggest issue I have with all the integrated ones, whether Renogy, Victron or anyone else is noise level. This doesn't matter if the unit is not in inhabited space and far enough away that it doesn't matter, but if it IS in inhabited space then it really does matter quite a bit. No idea on reliability but it absolutely does put out the 120V, its sine-wave, and at least under light loads the fans never come on. Someone should figure out how to have ambient cooling except under heavy load and essentially be silent in something like the Victron MultiPlus (or equivalent Renogy) units, but until they do if noise is a factor separates win for that reason, along with charge being independent of the inverter being turned on.

so far so good

Cables are rated 200A with 3/8” Copper Eyelet Lugs, excellent cables. These lugs will work fine with 5/16” marine terminals. For 1/4” terminals, you’ll need a washer. Arcs pretty aggressively, recommend connecting positive line first while unit is switched OFF. This is a sign that there are big caps and might handle big inductive loads well. At 180W, fans are completely off. If you put your ear to the unit, there is an almost imperceptible hum. The tone is lower pitched and is not bothersome or even detectable from a few feet. Connecting/Disconnecting smaller 100W inductive loads doesn’t cause power loss like in cheaper units such as Potek 2000W Pure Sine Wave inverter. At 320W, fans are still off. The hum is now almost undetectable with your ear to the unit. At 1050W, the fans are still off and still almost exactly 120V AC. I’m impressed. All lines and terminals are ice cold. The hum has taken a new tone, but it is barely detectable with your ear to the unit. At 1130W, the fans are on low. Unfortunately, a high frequency squeal is added to the noise profile that I can hear from 20 feet away. I have young ears (age 30s) and can hear 15kHz+ no problem. You probably aren’t using this thing as a pillow at night, but just be aware. I'm calling the upper limit at 1100W continuous for my personal use because the noise drives me nuts. YMMV. At 1600W, my battery bank voltage drops to 10.8V which may indicate that I am reaching the limits of what loads I can reasonably test with only two batteries and low charge. The fans are at medium speed and we’ve dropped to 110V AC. The high pitched squeal is very slightly louder. It seems like the fans are responsible for the squeal. I will recharge the batteries and retest higher loads tomorrow. I am running out of appliances! This is the first inverter of four that has met, and actually exceeded my expectations. You get a lot of bang for your buck with this one. Literally the only issue I've come up with is the high pitched squeal at 1100W+, which is well above my camper van base load 98% of the time. I am a HAPPY CAMPER thus far, thank you Renogy for actually delivering a product that meets and even exceeds its specifications. This is my fourth inverter; all previous inverters were returned for one or more serious issues. At least one reviewer listed the soldered 25A fuses on the mainboard as an issue - they managed to blow one or more of them. I like this unit so much that I don't have the heart to test.

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.

So many Inverters out there and I've bought the junky ones as well. I blew of 2 other ones already so I tried this one. I believe for the price this one offers some quality parts for the price. I use it in the RV, runs hair dryer(1875watt) microwave and anything for 110v plug. I tried running my ac which will run on 110v however the surge kicks out the inverter. It wasn't a deal breaker and Ive had 6000watt Inverters(CLAIMED) that wouldnt run it either. I guess a home breaker must allow quite a lot of surge power since it will run on a home 15 amp.. But haven't found any inverters that will run it. Its quiet and has long remote cord, It also trips and easily resets. < cheap ones just fry,,, It's nice to have our RV have everything without a generator. Just solar, never need to plug in unless you need AC Hope it lasts!! But I think for the price its the best one on AMAZON right now.
