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

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 far so good

I like this .. and I'm hard to please. This is the third inverter I have put in my RV. the first one ... Chinese stuff...stated it was a 4000 watt... lucky to be a thousand. Need I say more. The second one was Vevor junk. yeah you heard me right VEVOR Junk. This one is working exactly the way it should. And a great price point too.

After reading many reviews and shopping for the best medium range, true sine wave inverter, I ordered the Renogy 2000W 12V unit. After careful consideration, I did decide to purchase a unit twice the size of what I probably needed. This appears to be a safe choice! I've seen way too many bad reviews of the low priced inverters! I'm impressed with the quality of this unit. It delivers everything promised, and doesn't break a sweat. I just built a 200ah LIFEPO4 battery pack, with a 100 amp BMS, set to 150 amp overload protection, and used this unit for testing. It did great with a heat gun pulling 80 amps, but when I overloaded it to 180 amps the BMS immediately shut off, as it should. I'm impressed that I am able to charge the wife's Tesla Model Y, with the standard mobile 120v charger, at 4 miles per hour through this inverter, giving me about 8 mile's charge with the 200ah LIFEPo4 pack. I don't really intend to use this for charging her car, but decided to try this as as a load, while I tested the battery pack/inverter, rather than continuing to waste energy with the heat gun I was using. So far, I'm impressed!

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.
