I bought this for a friend to get her start in solar power on her house. It is plug and play. We had it up and running with two solar panels I gave her in about 15 minutes. You can't get electrocuted by the plug, it has to be plugged in and detect electric inside of the house. After it detects electric it will start a 90 second count down until it starts feeding electric to your house. In her case this unit and the solar panels basically cover all of the light bulb use in the whole house.Only one con. The con is the meter seems to need to be covered, there are exposed wires. We got an old clear tupperware container, took the lid off, cut a slit and hole in the side of the body,then we put the meter and part of the wire into the container, duct taped up around the hole and the slit, then snapped the lid back onto the container, which helped strengthen the slitted area and the unit is waterproof and you can read the meter through the clear container. We still like that they put the meter on this unit though. It's fun for my friend to look at the meter and see how much electric she is producing.

It overheats with just half the input wattage and shuts off. It'll start up again, but I doubt it'll last very long if it's having to shut off so often.

I used this inverter with two 200 watt panels. The data monitoring screen was really helpful and let me know my panels were working immediately. I put the monitor into a weatherproof box that is mounted under my panels, which lets me see how my system is doing without having to do any complex wiring.

I've had one of these running for about a week now with no issues. Power productions has been very low due to cloudy weather and testing various panels and configurations. Currently being powered by 2 200w bifacial panels in parallel for almost a day now. With good sun and the new configuration, production is starting to look good. Almost produced 1kwh from noon to 5pm.I purchased this inverter more for testing and curiosity than any serious application. Next testing will be at the max 600w input once another panel arrives.Do check the fittings as some of mine were not tight causing a potential issue with being waterproof.

The device started an unstable behavior right after the Amazon return window ended. The behavior is the same as the overheating behavior except in this case it is cold temperatures rather that hot. The specifications says the unit will work down to -40C. Worked ok in moderate tempratures but not in single to low twenties F temperatures. I visited the Y & H website, started a chat session but no one responded to the chat window. Get what you pay for I guess.

Review is for Y&H 1200W Solar Grid Tie Micro Inverter with AC Data Monitoring Display Screen.....Let me start this with saying we have a large solar system on our house, grid tied.I wanted to buy additional panels to supplement our system. Due to the fact that we have a net metering agreement with the local utility, we can't add more panels. Well....yes you can if you use something like this setup.I purchased this in December 2023 and originally had 4 Renogy 100w panels connected directly to this unit, since it can take 4 direct connections. I found the total output from the 4 panels, really lacking, and far less than they should be outputting, even in direct sun. So, I changed them to 2x2 in series. So only using 2 connections. The panel output almost doubled. Then I went and bought 4 more panels, this time from JJN, again 4x100w panels. This was in Jan, 2024. Thats 800w of panels, which we all know you aren't going to get 800w out of any setup like this. I was monitoring the output on a very sunny day, panels maybe NOT in the ultimate setup location as far as angle etc, and was able to consistently get on average of 550 to 600w. I am hoping for a higher output in the summer time. All purchased from Amazon, including solar cables from Renogy. Truly plug and play.OVERHEATING....I think that users are overheating this inverter by adding too high of panel capacity by using 4x300w panels. Cooks the system, it gets too hot, shuts off, cools off then turns back on again. Yes it is rated at 1200w PEAK, so you would think that 4x300w panels would be good right? I don't think so, based on others experiences, so I went with less expensive 100w panels. This unit has not overheated, not even once. I live in Hawaii, and all year round, our hot Hawaiian sun is killer hot. I mounted this inverter temporarily in the shade, outside, and it has been just working great. I hooked up a kill-a-watt meter to the system and measuring about 2kWh per day from this simple setup. More actually, but I am just rounding numbers and not inflating anything, so you know what to expect. Grid tied, so its just plugged into the outside house 110v outlet. I also bought a 50' 10AWG/15amp extension cord to run it to the outlet. (which isn't far away) System is working great, saving $$ everyday. According to my estimates, ROI for me will be about 3 years of use. We still have plenty of roof space, and this is working so well, I may invest in another system like this. You can never have enough solar power, and since I already have net metering and a grid tie system, there is no problem feeding power back into the grid and getting credit for it. This may or may not meet your needs for your setup.So bottom line, just don't connect up 4x300 watt panels and you probably will be fine. All 8 of my panels are connected in series, which raises the voltage, (2 panels each in series, connected to each input) but keeps the amps the same. Excellent for 100w panels connected this way. This inverter is actually 2x600w inverters, connected internally, so the connections on the unit, are top left side and top right side go to one inverter, and the bottom 2 connections go to the other one. You then connect up the supplied monitor, and plug the inverter into an AC outlet so that it senses the 110v and turns it on. The power supplied by the connected panels, then gets converted to AC power from DC, and straight into your house system. For safety, this inverter will NOT function if there is no 110v power detected coming into the unit. My kill-a-watt meter, shows slightly higher watts, amps etc going into the house as opposed to the monitor that comes with the unit. You will need to figure out some weather proofing for the small monitor unit...something the manufacturer should address. I do not think that mounting this unit under the panels with not enough air flow is optimal, since there are no heat fins on this unit, but as I said, no heat issues so far...most likely due to using the lower wattage panels. Very pleased so far with the performance of this with minimal investment.*update* 03/2024This has been performing just great. I am getting consistent 700w on sunny days, and figure once we are in the summer, that should be the norm, if not higher. Does the inverter get warm? Yes it does, since it is doing the voltage conversion, which creates heat. I have the unit mounted in the shade, with air flow, but was concerned about the heat of this unit, even though with the 8x100w panels, it handles this like a champ, much less watts than the rated maximum. I am actually considering picking up another one and adding 4x220w panels. Ok, for cooling the inverter, check this out: https://www.amazon.com/gp/product/B0CR1DC1RB/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 This works fantastic! Large solar panel, no batteries needed, no extra electricity, just put the panel in the sun, mount the fans and away you go. The hotter it gets, the faster the fans work. Great system, and keeps this inverter very cool. To use that solar fan combo, I had to reverse the fans in the mount, but once I did that, it works great. Why not use the sun to power your cooling fans? Win. I think I will give this at least 6 months of use to see how this holds up overtime, before expanding the system. Electric rates in Hawaii are super high, so adding solar to your home is a no brainer IMO.*Update* 8_15_24Still going strong with ZERO issues so far, connected 24/7 since installation. I think the only time I had it disconnected since install was for a brief time to re-route some wiring. No complaints so far.

Works fine with travel adapter. Display shows all data and gives more than enough info. Not the best solution, if possible to change the power plug it would be even better.Green, blue and light from display shows it is working as intended - easy to see from distance.

I really want to like these, I designed my setup around them and the first one I bought worked great! It got a bit hot so I designed a control enclosure around it to mitigate the issue and purchased a second inverter. Well the honeymoon phase ended and the second inverter lasted a day before going into protection mode just like the two successors I replaced it with. I'm not over loading the input and keeping them cool, so it must be a production issue. Very disappointed and going to utilize another inverter in my system after I return all four of these.

My DC output from the solar panel is 116 watts. When I connect the inverter the output from the inverter is only 10.4 watts AC. This translates to an efficiency of about 9% for real AC output. The Power Factor is only 0.25
