Y&H 600W Solar Grid Tie Inverter MPPT Pure Sine Wave DC26-46V Input AC180-260V Output for 36V Solar Panel Balcony Power Station

Bought 3 of these, all 350W. Great price compared to microinverters available in the UK. All still working well after 12 months.

The media could not be loaded.  I bought a 300w one from Amazon and a 350w from ali baba. The Alibaba.com 350w has already burned out its mosfets and they won’t replace the inverter. The 300w Amazon one worked great first few weeks then reduced its output by 70%. I have a 265w panel connected to it and at the beginning I was getting 150-230w now I’m getting 30 -50w max in spring sun. What a shame this product couldn’t been a game changer in the solar industry. I’ve gone back to the old trusty but inefficient 1000w inverters for small installations. Please Y&h fix this problem. My inverter is more than 6weeks old now and I can’t even get my money back. What a waste of hard earned money. Very disappointed

I attached a 345watt solar panel to this inverter and it powered up as soon as it was plugged in. It runs quite cool below 150 watts but starts to heat up proportionally as the load increases. I fastened a heat sink to the front of the casing and also put a solar powered fan above it to help keep it cool. The casing needs redesigning to incorporate some cooling fins as I'm sure it would overheat and burn out at full load without these supplementary cooling measures

Spot on just the job

I got the 300w version to run a pair of solar panels totaling 160 watts, with the idea of getting a larger panel later. The inverter worked fine most of the time with peak power going to the grid around 140 watts (as measured by a power monitor plug) Unfortunately the first one I had blew a fuse and I had to get a replacement which lasted around 7 months, but that too blew a fuse. The vendor is keen for the purchaser to self repair the inverter, but I was not willing to play around with the insides of a mains device, (you have to take the device apart to replace the fuse), so requested a return/repair.The vendor also wants the purchaser to pay for the return and also make a declaration on the custom form to specify the value as being 20 euros which again I am reluctant to do as this would open me up to claims of fraud. As a result I had to get Amazon to intervene , and they have said they will get the vendor to arrange a free return.EDIT: If you do decide to go with this, and run it at anywhere near its rated power, it might be worth checking to see if the covers have been removed from the thermal pads - on mine the blue plastic cover was left on the pad which sort of defeats the purpose.5 stars to Amazon, but only 3 for the vendor/device.

Does what it should, but the leave the blue tape on the thermal pads, recommend a disassembly takes 2 mins

So a lot of reviews say it gets hot and the cure is to remove the 'forgotten' blue bits of plastic behind the FETs and the body.I did that before powering it up.Unit rated at 350W. The most I've fed into it is 244W from two old panels I have in bright sun. It gets hot to the touch (hot, not warm, burn your fingers hot if you hold on) but runs well and gives consistent output.Mine is installed on a wall inside a cold garage with low ambient temperature.Doesn't cut out at 244W and seems to be happy to do this for hours at a time.If this was fed the rated 350W I wouldn't fancy it's chances of surviving long without active cooling and even then I suspect it would need one more MOSFET than it has.I wouldn't trust it somewhere where I could not get easy access to replace it (i.e. on a rooftop behind panels), but that's not what I bought it for. I bought it to be able to use two old panels I had spare and it does that well.

Garbage. failed after 2 months. Seller offered to send parts so I could fix it, but I must pay them for the shipping form China. Its clear they know about this as they mention it in the description.They know they are selling junk that has a limited lifespan.They know you can't do anything about it.The only thing you can do, is, not buy this cheap garbage or indeed any of the cheap garbage they sell and then hopefully they'll stop selling their faulty wares on here.

Testweise habe ich den Inverter an einem 100 Watt Modul mit Netzfilter betrieben.Im Originalzustand ist die Einspeiseleistung relativ schnell von ~60 Watt auf 15-24 Watt schwankend reduziert worden. Gehäusetemperatur geschätzt 50 Grad.Im nächsten Schritt habe ich die blauen Folien entfernt und das Gehäuse wieder geschlossen.Den Schutzleiterwiderstand konnte ich nur mit einem Ohmmeter messen und habe ihn mit ~200mOhm für mich als ausreichend erklärt. Das ist keine ordnungsmäßige Messung und sollte nur zeigen ob das Gehäuse angeschlossen ist.Nach der Änderung konnte ich über 3 Stunden 58-70 Watt einspeisen. Außentemperatur um 30 Grad.Mit Kühlkörper und Belüftung erwarte ich mehr.Da aktuell keine zugelassenen Inverter in dem Leistungsbereich zu bekommen sind lautet mein Fazit günstiges Gerät für Bastler die wissen was sie tun.Bei meinem Gerät rastet eine Buchse nicht ein. Ich werde beide Eingänge mit längerem Kabel und neuen Steckern versehen. Nochmals, nur für Bastler geeignet.4 Sterne für die Verfügbarkeit und Funktion nach Modifikation.Nachtrag: am 100 Watt Modul ist direkte Sonneneinstrahlung erforderlich, also Kühlung verbessern und größeres Modul anschließen.

Die Inverter kamen bei mir mit falsch montierten Wärmeleitklebern an. Ich musste bei 4 von 4 Modulen das Modul aufschreiben, die blauen Folien beseitigen und das Modul wieder zusammen setzen.Das ist nur eine Fleißarbeit und war in 10 min pro Modul erledigt.Mehr kann ich noch nicht sagen, da es seit Tagen regnet.

Man sollte besser ein paar Euro mehr investieren, trotz dass die Leistung längst nicht ausgereizt ist läuft der WR giel zu heiß. Eine Rückgabe ist bei diesem Händler ebenfalls nicht möglich trotz Fristeinhaltung.

Der China-Inverter wurde schnell und belastbar verpackt geliefert und funkioniert. Abhängig von Panel und Sonneneinstrahlung schaffte er bislang ca. 80% der Leistung. Etwas starke Wärmeentwicklung durch fehlende Kühlung bei bis 60 Grad, dabei schaltet es dann mitunter kurz ca. alle 30 Min. für den Bruchteil einer Sekunde runter. Bei dem preis und kleiner Anlage kann ich damit leben. Hoffe trotzdem er hält langfristig.
