Y&H 1200W Solar Grid Tie Micro Inverter with AC Data Monitoring Display Screen Waterproof IP65 MPPT DC28-50V PV Input AC80-160V Output for 36V Solar Panel

Works as advertised. I got four used 250w panels and connected them. Plugged this in and out came power. Really easy. But I found out this is NOT UL approved and you will not get certification to connect to your house. Electric company and others (town?) will not approve or support (in USA).

worked less than 3 months and half of it died with a direct short across the solar panels. There is no warranty and no response from seller so assume its AS IS and may fail soon. Granted I have it in a cool dry spot with fans blowing on it. There is no way these will last under a solar panel like the seller claims.

Great Device. Im using it to add my old Solar panels to my current system. It worth the money.

STAY AWAY FROM THIS SELLER!! I bought the 600 and the 1200. Both quit working and the seller will not answer any email or messages. Minecraft under warranty but I cant get them replaced because they wont answer my warranty request.

I've installed with 100w solar panels in series, and it works great as expected. Terry G did you ever purchase 200w panels for a test, I'm thinking of putting 1 200w panel in series with 1 100w panel on each connection that will keep me under the 1200w as you never get the full 300w in each leg. Just wondering if you have tested the 200w panel setup.....ty

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* 03/2024 This 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_24 Still 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. *Update* 12_13_25 Same. Still converting that solar with same connected panels. ZERO issues. ZERO upkeep. Placed outside, under some cover from direct rain, but this unit does get wet when it rains and its windy.... *Update* 2/26 still working without problems, but I changed the setup......This unit has the 4 inputs, and I have feeding the system, 8x100w panels. I changed how they are connected, seems to be a little more efficient on the inverter....top 2 inputs 4 panels connected each input, 2x2 in series, then parallel the 2 series connections into each input. For my system, and the placement of the panels, this did not overload the inverter, and getting around 500-600W max showing on the inverter....this doesn't mean that the panels are only putting out that much, loss in conversion etc, but in connecting this way, I free up the 2 empty inputs, so I connected up a 350w portable panel to one input. Its this one: https://www.amazon.com/dp/B0DSFT9FZT ZOUPW. All working fine. Adding this panel gives me over 800w in pretty good sun. This panel alone, connected to this inverter, and using the W info on the inverter meter, gave me around 275w in good sun. Keep in mind what I wrote earlier....you will overload the inverter with more than 300W per connection, but if this happens, just change the angle of the panel to reduce the input. This panel is right in the sweet spot for voltage that this inverter likes, from my testing. Connecting the 100w panels the way I did brings the voltage into the 40-50v range. Also keep in mind I am cooling the inverter with fans, which I am sure helps. I do not plan on keeping this portable panel connected at all times, but very easy to deploy when wanted.

Está perfecto lo conecte con 8 paneles de 100 w y me da 600 w está muy bien y con 8 paneles no se calienta mucho 👍👍👍👍Gracias

is a good deal but is not working. The display stop showing any numbers and no technical support. I will try to contact them and maybe solve it. but is not good. as I work on all the system and now is not going to function when I need it. If they change the display may work. Yes the blue light is on but I do not know if is working or not as no numbers.. I will try to help the store solve it as we need such product.
