Not according to the link I provided. Many of the EASuns look significantly different from the Voltronic originals. I'll admit that not all look different, and for a while I believed that they were genuine too.

It's possible, though unlikely, that some EASuns are clones and others are genuine. I suspect that of Synapse labelled inverters, for example. I wish that Voltronic would provide a way that customers could easily tell. Just a list of genuine brands would do me, though keeping that list up to date would be a hassle.

I opened 2 of them from MPP and Easun and they have identical components and identical Voltronic numbers, so I want you to post pictures for identical models and prove components are different and that it is being used another factory.

Your article does not provide pictures from components and just make assumptions without knowing that Voltronic is producing batches as OEM products with the label each order wants (Apex, MPP, Easun, PowLand, Axpert, SMKSolar, Mecer, RCT, Kodak and another 20 more OEM labels, all produced by teh same factory with OEM license and they apply your label, with your brand.

So we have at least 30 brands and also 27 different models with different characteristics, but all are int he same factory produced, not clones as you claim without in depth components analysis. Also last year because of semiconductors variations you will see the components being changed more often becase they could not find supply for big numbers of what they have been using.

Otherwise it is just another way for an expensive label for a product produced in exactly the same big factory, Voltronic !

I think what @Coulombis trying to say is, you have a clone/copy/fake of the real thing.  If it doesn't work with the software they provide or software of the company they ripped off, you are probably out of luck.  Not many people are going to want to create software for a clone.  Partly because it is disgusting that they rip-off another company but mostly because the clones have bad build quality.  So most people with clones end up needing to replace them soon anyway.  You aren't paying much less and you are getting a worse product.  So not worth buying the fake.

You probably didn't know you bought a fake, so it may be worth seeing if you can get a refund and buy the real thing.

Easun inverters are manufactured and assembled in Voltronic factory.

Wat makes you tell that if the same factory rpoduces the same inverters labeled as MPP, Easun, Apex and many others that put just  alabel on them, makes one the original and the others a copy ?

Just asking for a clear understanding on your lack on information that make you think that if you pay $1000 for one inverter and $600 for another one produced in exactly the same factory make you tell others that if you pay more mone for the more expensive label you get better quality ?!

Do you understand how OEM factories from China work, they offer OEM products.

Cheers everyone

The EASuns are clones. So who knows what protocol they support, what quality of parts are in them, etc.

can you open the video and see all components maybe we find who produces the inverter and the protocol used because it is a modbus device.

It's possible that the inverter does not support WatchPower. Can you identify it against one of the genuine Axpert versions then check?

I recently bought an EASun Isolar SMG II 5KP and had exactly the same problem. It has no USB port, the COM port identified but no communication with WatchPower. I asked EASun and they confirmed it didn't have (this version of) RS232 comms. Maybe the clue was that there was no CD in the box even though there was a cable and it mentioned it in the user guide.

Fortunately they accepted the return and I bought a different version that does work with WatchPower.

Did you receive a CD?

It must be using a different protocol and we need to idetify the other models thata re identical to this one.

I opened ISolar SMGII 5KP and it has both USB and RS232 cipsets and connectors and you can see all connections and board by downlaoding the video below and I also attached 2 pictures :

Any suggestions about all the other cloned models that are similar to this one ?

I want to find what other known inverter models are identical to this one and that have known protocols. Maybe it is GEN II from the name ?

A video with exact SMG II components can be downloaded with high resolution from here (not preview)  : https://drive.google.com/file/d/1vTVmUU79kyTTm4LnIqdnN-FFFqlcMHiT/view?usp=sharing

I want to connect with Rasbery Pi to this inverter i have https://www.aliexpress.com/item/1005002328132162.html

It works  with provided  WiFi Dongle and SmartESS application but Solar Assistant does see incorrectly the devices when connecting both usb and rs242 cables together or independently.

when plugging in the inverter via USB it's showing up as a "Exar Corp. XR21V1410" serial device which is different from normal.  This USB device is also not accepting connections.
