Renogy 3000W Pure Sine Wave Inverter 12V DC to 120V AC Converter for Home, RV, Truck, Off-Grid Solar Power Inverter with Built-in 5V/2.1A USB, AC Hardwire Port, Remote Controller

Added this inverter to a camper that didn’t have a 120 volt system besides shore power. What a great product! The Bluetooth data is awesome. I ended up added a smart hub and a battery shunt, too, just for more info! The inverter is very well made, supplies a legit 2000 watts, will run my A/C system (while batteries last) and will power a microwave I installed. It’s a good upgrade and adds lots of functionality to the camper. Highly recommend Renogy products.

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.

Took a trip to Yellowstone and was on the road for a month. We packed a ton of food in the fridge knowing that groceries are scarce and expensive in that area of the country. We had swapped out our absorption fridge for a residential fridge and needed a way to keep our fridge running while driving all day for a couple days in a row and while boondocking at overnight stops along the way. I replaced my marine deep-cycle battery with 2 Renogy AGM batteries and added this inverter. I then ran an extension cord to the back of the rig, up through the floor to behind the refridgerator. I then opened the rear vent panel on the rig to plug the fridge into the extension cord from the rig outlet. Turned on the inverter and had power to the fridge the whole time. When we were connected to shore power I turned off the inverter and plugged the fridge back into its normal outlet. Worked great and the frozen food stayed frozen! Easy to use and install and made with very good quality components (from what I could tell). Very happy with this purchase.

I purchased this inverter almost two years ago for installation into my RV. Early on I stress tested it by running two electric space heaters at the same time for the nearly three hours it took to drain the lithium battery bank. Roughly 170 amps continuous, or very close to the 2000 watt rating. The inverter fans cycled on and off but the inverter kept going. In the roughly two years since purchase there's never been a problem with the inverter.It powers up the trailer microwave no problem. Microwaves can be a problem, they are very inefficient. The one in the trailer is rated at 700 watts but according to the exterior label consumes 1100 watts to make the 700 watts inside. Microwaves also have a huge surge every time the magnetron starts, so it can be hit or miss depending on the specific microwave and inverter combination.The remote on/switch is handy. When on the inverter does use a noticeable amount of power if left on overnight, but not enough to be a bother to me.Normally the inverter is silent. The fans only become noticeable, and that's barely noticeable, under a constant heavy load, which in my use is pretty rare.
