Y&H 1000W Grid Tie Inverter Stackable MPPT Pure Sine Wave DC15-28V Solar Input AC90-140V Output for 12V Solar Panel

I got this just to play with a 100w 12v solar panel I bought to take camping and figured why let the solar panel sit 90% of the time? So I bought this GTI. Since then, I have upgraded to 2 solar panels (Rich Solar - https://smile.amazon.com/dp/B07DPHY2YJ/?coliid=I27A31NPTEGY76&colid=33U0EES65JEM1&psc=1&ref_=lv_ov_lig_dp_it) in parallel running to this inverter and am planning to add 4 more panels.I have this running through a Kill A Watt (https://smile.amazon.com/gp/product/B00009MDBU/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1) and in full sun, I have seen it pushing 157 watts back into the house grid. This was the first of November running them through about 10meters of 10 gauge wire and connected directly to the GTI using the o-rings crimped on the cables that came with this inverter.I got this set up the middle of October, so we have not had many sunny days as I live in the suburbs of Seattle, but when there is a full day of sun, I have seen a couple days were I was able to get 0.72 kWh or 720 Watt hours pushed back into my house grid. Not going to eliminate my reliance on the utility company, but for $320 total setup cost, it will only take about 2 years to pay it back.Something I noticed, when I first hooked this up, I only had a single 100w 12v panel, and any time there were clouds, it would drop the voltage low enough that the inverter would stop working. Since adding the second panel, I have not seen that happen. There have been times I have seen 10 watts being pushed through the Kill A Watt on a cloudy day.Definitely something I would buy again!

I have used this Grid Tie Inverter for just over one year with a 24VDC battery bank to offset grid power usage during high-cost electricity times (4pm-9pm in my area). The inverter stopped working yesterday, so I checked the fuses and all three 30A fuses were blown. I replaced the fuses, reconnected everything, and turned the inverter back on. There was a loud "pop" and sparks flew out of the inverter through the fan shroud. I'm glad I was standing right there to quickly disconnect the 24VDC power before things got worse. I think this is a great idea, but a poorly executed design. Certainly not worth the risk of catching the house on fire.

Great Inverter and easy to setup. Works Great and within the budget to product power from you SOLAR and/or WIND Turbines. Setup in Summer 2022 and Still working great as of 1/12/2023. Missouri Wind and Solar 2KW Wind Turbine charges batteries and Y&H Inverter converts DC (24V) to AC. Nice!!!BTW.. Y&H provides great support for questions and setup. I asked them for setup info on this on their Y&H higher end KW inverter (120/240) and they came back with 24 hours with HELP. Terrific support.

Most of the comments in feedback regarding the unit getting very hot, YES, Because the cooling fan in these units is a known issue. I have had 1 of the 600w units and 2 of the 1000w units and in every single unit the fan died after a few months. Replacing it with a fan that has bearings makes the difference and will keep the unit going. No the chasse should NOT reach 200f. its should always be cool to the touch. Loud fan noise means its on its way out and is not cooling like it should be.

Unit functions, but only at 480w output. I have tested it over a three week period and the most i have seen is 3.75amps output from the unit. It does run warm, but the cooling fan kicks on for 15 to 30 seconds and it keeps the unit at 104 degrees Fahrenheit. If you are looking for a grid tie inverter that works but not at 1000w as advertised then this one is for you.

Worked great for my experiment

Used with 24V 200 Ah LiFePO4 battery system. Worked well for 8 months, but then it stopped working and I smelled a burning electronics smell. Will see if warranty covers it. Not the most efficient, round trip efficiency of 65% when you include the energy it takes to charge my batteries, the inverter itself is about 75% efficient. Using for time shifting peak demand offset 5 hours per day. Also if the fan is on when you power it off, the fan keeps running, which is unfortunate. So I have to program it to come back on again for 1 minute after a 20 minute waiting period when I'm done for the day, otherwise the fans will keep running off the 24V batteries even though the unit is no longer connected to the grid. Definitely much less expensive than any other grid tied inverter that I have found, and company has been responsive to support questions, so we will see if another unit will last longer.Update - 2nd unit lasted about as long as the first. Less than a year. Cannot recommend this, unfortunately.

I've had this inverter running for a year now and I haven't had one problem with it. Using 8 100W Texas Solar panels all running in parallel. The unit is in the basement hanging from the floor joists. It has never tripped offline from heat or over current. This was a proof of concept grid tie install. It runs on it's own dedicated 20A circuit into the service panel.If you have a small house or don't need to offset a very large amount of power then this little guy is for you. In the year it's been running, it's more than paid for it's self.If I were doing this again, I'd use a version that can handle more voltage to reduce the loss in the cable, and/or use higher gauged cable.
