Y&H 600W Grid Tie Inverter Stackable MPPT Pure Sine Wave DC30-55V Input AC230V fit for 30V 36V Solar Panel/36V Battery

I bought this to replace a smaller unit which failed spectacularly when I used my electric drill near it. I have put a full spec mains filter and a VDR spike killer in between this one and the mains, and put a 1A quick blow fuse into the 13A plug (my solar panel is only 200W, so 1A is enough for me, you'd need 3A for full power).I've used the drill again without any problems.Sadly this suddenly failed after three weeks. Couldn't contact the dealers so returned to Amazon for a refund.

They are a decent solution for adding some juice to your grid with a bit of solar. I have bought three. One was faulty out of the box and was replaced. My longest running one has been used for 10 months. It is now faulty. Fuses all ok and voltage to unit inspec etc. Because of the stupid return policy and complete rubbish warranty from manufacturer/supplier I will have to buy another one. Slightly annoyed as this one was dispatched by Amazon but supplied by Y&H. So note to others only buy from Amazon if possible as they would have to honour your consumer rights and replace when it goes faulty in a reasonable time. I don't consider one year a reasonable time. Annoying.

Lasted 6 months in my shed but didn't like the electrical noise from my electric chain saw.The internal varistor clamps at 710Volts but the MOSFETs are rated to 550Volts.Good thing is they seem easy to fix with up-rated components. Just be careful as dangerous voltages within.

I have a 24v home power storage bank comprising 6 x 12v 100ah Leisure batteries pairs connected in series and then each pair in parallel to give me around 2.5-3kw. These are purely as overflow to my. main solar system to limit the amount I export to the grid. Once my main grid tied batteries are flat I then manual switch over to these using this unit. It provides 600w for around 30mins and then settles down to around 550 for 1-2 hours slowly degrading as the batteries flatten. It is almost linear. Obviously you must make sure not to allow the Lead Acids to drop below 50% but which this does NOT seem capable of doing. You don't have to use batteries you can just plug your solar panels directly in if you have off grid panels.

SECOND UPDATE: The third one I bought continues to work well after a total of 8 months online. HOWEVER - I have discovered that while it is operating it is disrupting my LAN over mains POWERLINE.UPDATE: I bought another one of these (because they were the only grid tie inverter for my input voltage that I could find.) It worked superbly from May 2021 until I disconnected it in Autumn, then again from March 'til today July 2nd 2022. Today it has started blowing 3amp fuses..... so I stupidly connected it directly to a socket using the lead they provided.Imagine my surprise when there was a flash from inside the unit and all the ring mains in the house tripped out..... and triggered the RCD breaker in the fuse box.I opened up the unit and there was a plume of explosion debris on the PCB in front and behind a component I didn't recognise (a bit like a 1/2 watt resistor) just next to the mains cable connection.So..... If you want one that will last more than 13 months I suggest everyone looks elsewhere.ORIGINAL REVIEWI was initially very happy with this - I had had one in the past that ran unattended for years, this one didn't last a week of occasional operation.Because I am a cautious person I connected the inverter to the mains via a short extension lead with a 2amp mains fuse in it. It, worked fine with that setup for a week.When the inverter stopped working (connected to 200w of panels, so no more than 1 amp of mains) I found that it had blown the fuse in the extension lead..... so I replaced it with a 3amp fuse. Reconnected everything and it instantly blew that fuse. Eventually I replaced the fuse with a 5amp fuse and tried again (which should have been sufficient for over a KW of power) - this blew instantly as well.My conclusion is that there is a short inside the unit on the 240v side, which is blowing fuses in the mains cable connecting the unit to the house. Since the unit is only supposed to draw 1 watt, and only produces power from my 200w of panels there is no reason for it to blow a 5amp fuse.It worked fine through a 2amp fuse for a week, so I have to conclude that the unit has simply failed.I have sent it back to Amazon.Sadly this is the only sub 1Kw, 12v -> 240v Grid tie inverter I can find that doesn't need permanently wiring into your house by a professional. So I have ordered a replacement......ever the optimist.But if you don't need to buy this model, I would recommend looking elsewhere.It deserves a 1* rating - but since I have bought another it feels a little hypocritical so I have given it 2*

Lots of pretty LEDs flashing away but it works just fine.

Failed after a month. The supplier tried to get me to do a "simple repair" which was anything but simple and wouldn't fully pay for a engineer to fix. Then tried to get me to send it China for repair so I returned it to amazon for a refund. Apparently this is a common fault. Avoid.

Just the job works a treat.

Die Einspeisung in das Haushaltsnetz und die Synchronisierung mit dem Stromnetz beginnt nach wenigen Sekunden Nach dem Einschalten. Die Leistung ist offensichtlich von der Eingangsspannung auf der DC Seite Entscheidend. Bei 24 V DC erfolgt eine Einspeisung mit bis zu 200 W. Bei 12 V DC Bringt der Wechselrichter eine Leistung von bis zu 100 W. Das ist aber für meine Erfordernisse ausreichend da ich nur die Dauerlast zu Hause abdecken wollte. Die Wärmeentwicklung und Betriebslautstärke sind in völlig annehmbaren Parametern. Eine Kaufempfehlung für das kleine Geld.

Hält ein paar Monate dann ist Feierabebnd.

Nach 3 Monaten Defekt.Nach 3 Monaten mit nur 180W Betrieb Defekt.
