Let us know if your inverter works as it should, or it has the same issue. From couple other purchases that were done by my friends, it seems they still suffer from the same issue - unless something changes in the last month-two.

Yes, once you do that - it works properly. :) So, for full offgrid it would be OK.

@@IgyBoyCROyou need a 2P or 1P+N breaker on grid input, this is “normal”. Well, “Easun normal” 😂😂😂

Where do you download the firmware? Thanks.

Hi, each input is for its own. So, each can handle 500V.

Haven't got time to play with it. There is obviously some firmware being released by Voltronic that fixed "some" of the flaws on the inverter but I don't know which ones. Winter is coming so I might give it a try in a month-two

Hi, yes and no. I have installed it and use it here and there to adjust parameters on inverter.

Tnx for sharing. Yes, it was confirmed with Chinese that the algorithm used here is the same one use in low voltage versions - which means it is not optimized for the wider range voltage and can easily "loose" the MP point. :/

​ @IgyBoyCRO Easun finally emailed me the new firmware updated called 'mppt optimisation update'. Not sure I can post links here.

@@bengrimmett1239 Would be excellent if you have link to it. I believe you can post it without issues. There are more than few people reporting the same issue. I can (possibly)update the description in video to post the link to it.

@@IgyBoyCRO looks like youtube has removed the link, or its possibly pending approval from you

@@bengrimmett1239 Hi Ben, have you had any luck with the new firmware? Try uploading it to gdrive and send the link to that. Maybe the hosting site is blacklisted by RUclips, not allowing the link...

Hi! Tnx for the reply, but all those have already been tried and none works. I have spent hours on troubleshooting the thing. What is more important - I believed that only my unit has this issue, so I foolishly went on and purchased couple more units for my clients and guess what - all of them had the same or similar issues. So, my advice - stay away from this inverter. 5.5kw versions had none of those issues and work perfectly fine. If I simply drop in a 5.5kW inverter on the place of this one - it works without a blink.

@@IgyBoyCRO I have two units, friend of mine too and there are no troubles like you described.

@@radoslavtasky8805 What can I say. You are lucky then. :)

Unfortunately, no. I just gave up on having this inverter connected to grid. I just use it in full off-grid mode. It still has same MPP problem, can't be properly turned off, but Easun was unable to provide solution to any of my problems so far.

@IgyBoyCRO What version firmware you have? I have a plan to buy this inverter but in case of MPPT issue it's preferred not to buy this one.

Haven't got time to play with it. There is obviously some firmware being released by Voltronic that fixed "some" of the flaws on the inverter but I don't know which ones. Winter is coming so I might give it a try in a month-two.

Hi, the voltage of the panels is not related to the ground, so it "floats" in relation to the ground and is not a problem. You can safely go and use it like that.

I think this is some kind of leak from the inverter itself. It is not normal for cables with DC to have and AC power. Therefore, if you have the opportunity, please check if it is the same with you.

Negative wire being connected to the grid should not be an issue. If it doesn't have the live wire, it can't sync with the grid. The issue here is that, obviously the inverter can't work if the input neutral and output neutral are on the same line - which works perfectly with other inverters and is definitely a flaw either by design, or somewhere in the firmware.

@@IgyBoyCRO Hello, I asked EaSun about this issue and they told me that the N input and N output cannot be connected together. Did you try another connection?

It doesn't go like that with Chinese. First they stall you and bomb you with requests to do this and that and video record everything, send logs and data and whatnot only to stop responding. Somewhere in between I have requested that they deliver a new firmware, and I mentioned it a couple of times, but they just ignored it. The reason might be that they don't have a fix for this yet - which would explain why they needed the logs and data from the inverter. Other reasons: they just don't care and stall you untill you give up on pinging them.

alo drugar odakle si ti ?

@@MrSolunac Pozdrav. Hrvatska, Baranja. Ti?

am distributer of EASUN samo mi kazista ti treba i sta se desava ,nema problerma

@@MrSolunac Što je žalosno: i ja sam im bio distributer - do ovog i još dva druga slučaja kada nisu htjeli pružiti podršku za dva invertera. Prodao sam na desetke 5kW i 5.5kW njihovih (EASUN,Powland) invertera i onda zapnem na tri reklamacije. Strašno. Dok ide, ide...Kad zapne, nema pomoći od njih.

Hi, while it is offgrid it works OK. The only issue to be aware of is the one with MPPT not working properly on cloudy and semi-cloudy days. As for the reliability - so far it is OK. In this half a year I use it it was powering all sorts of loads: 2x 4kW air conditions for heating (15hrs a day), charging a car regularly, workshop tools, compressors,drills, water pump, and sensitive electronics - 3D printers, servers etc...everything in a house without glitch.

Unfortunately, no. EAsun has not been able to resolve the issue, and they are now not responding for more than a month. They asked for all sorts of videos and data, but none helped. I guess the board is faulty, or the firmware is doing something wrong. Anyhow, I am managing to use it to power the house - without grid connection(the other inverter I showed is doing the battery charging from grid). MPP tracking sucks, as the algorithm is badly implemented, and needs an firmware update, but I am not sure if I will get it from EAsun. The power off and power on is not bothering me at this point, but is just adding to frustrations over the inverter. Best part is: I have sold dozens of EAsun inverters(5.5kW versions) and their customer still ignores me. Now imagine if you only buy one single inverter. Getting the help from them in that case is close to impossible, as they will simply ignore you.

@@IgyBoyCRO thank you for your kind reply. So, you think you've got a faulty device?

@@kostaskostopoulos2913 I do not know. It could be a design flaw, or firmware error. Part of the issues are definitely due to the firmware bug(MPP tracking issue), other part of the issues could be both: faulty board or bad firmware. Unfortunately, I do not have high hopes that EASun is competent in resolving the issue, so I will probably need to disassemble it myself and check the board and possibly do reverse engineering of firmware to find the solution. But this is not ideal, and will cost a lot of time to do.

@@IgyBoyCRO I hope you will find the solution. I have ordered the same for a friend. I hope to receive it within next days. If you think I could help you, by coping the soft, if possible, or what else, please, just ask. 😀

@@kostaskostopoulos2913 thank you for the offer. I hope yours works properly. I will be dealing with mine probably in a month, as I am busy with other stuff at the moment, and I still hope Easun will reply(naive, I know). :) Good luck!

Yes. Fully disconnect the PV array is what works every time - you just need to remember to do it. If you are not at home...no luck, you will just loose that electricity. :/ Other inverters (even other, cheap solar inverters from China) are on occasions "probing" the array for MPP point in a way that it will drift up and down with voltage significantly, to see if it is still on proper MPP, and this will happen every once in a while. It is just how most of MPP algorithms work. This one seems to not have this functionality implemented or is simply badly implemented.

@@IgyBoyCRO i bought exactly the same inverter yesterday... f... Did you contact the assistance for that problem? is it available a firmware update?

@@rOSScOGITANS Yes, but after I reported it they requested that I upload/send them the data from the logs for at least couple of days when that was happening so they could troubleshoot it. But once I sent it, they stopped responding. :/

@@IgyBoyCRO i have deleted the order for sure, anyway it's a very rare model, no found other users of this inverter, no reports in some forum, nada de nada!

@@rOSScOGITANS It is fairly new model, so it might be that the later versions will come with all those issues fixed already, and I totally understand that this happens (at this price range it can't be perfect), but what annoys the most is not getting ANY support over the matter. So I can't recommend them really.

I could try doing it, but that is not a solution. I do not want my array arranged like that due to specific arrangement of panels. Part of panels is in the shade for a part of the morning and afternoon, and if I put them in a single string, I do not get the max power from panels, as those couple of panels in shade bring down the production of the whole array. Also, proper MPP tracking algorithm should work regardless of the amount of connected panels. The proof is the fact that it works perfectly once you force it to "rethink" the MPP strategy by disconnecting the array. Also, I have previously had the 5kW version of their inverter, with same configuration for solar charger (90-450V) and it worked flawlessly for years.

Well, turns out the inverter is total cr*ap. MPPT is also not working properly, sometimes it hangs for hours at 90V, while it should be near 200V (which is the nominal voltage for my array). I have a separate video showing this. While my other inverter produces 1kw of power this one just sits at 90V and wastes energy. Reported the problem and EASun asked to provide the data. After I already sent a video and offered to send the logs, I received no response on that topic. On semi-cloudy days this means a waste of couple hundred watt-hours if not kWh.On the grid-sync issue, EAsun has proven to not be worth the hustle. They provided no solution for the problem, and still require all sort of videos to demonstrate the fault. What is even worse, the inverter - even when powered down, provides power to the loads. I'll put the links to that video later. It is not publicly listed, and I have not edited videos for public showing, but now Im thinking of doing some lengthy video, counting and showing all the issues. So, if you were to ask me is it worth to invest into EAsun inverter at this point, the answer is NO! Invest some money and buy from MPP solar or other non-chinese inverter.

Thx , i bought an iGrid 5.6 SV4 while i missed your answer … but thanks for feedback

@@IgyBoyCROthere is a hacked firmware available to solve the 90V problem. Easun is a cheap clone chinese thing, don’t expect much…

Hi, yes, I do have to agree on the wiring. :) Althought, it is because the old inverter (also EASUN 5kW version )has just been removed and the new one was connected when the issue was discovered. Yes, the input AC neutral wire is directly coupled with AC out neutral wire. Most inverters work properly in this configuration - as it should be. The issue is not simple, however, and depends on how your house electrical installation is designed, and specifically I refer to the neutral-ground binding(check how different systems work by having a look at TN-S, TN-C, TN-C-S, TT and other grounding methods). Also, the EASUN itself(Voltronic, Axpert) recommend it to be connected this way. I could probably bypass the issue I am having here by doing the modification of the house electrical installation, but that is not an option. This has to work like this. Take a look at the MPP Solar inverter on it's side - it works like that for years. Even the previous 5kW inverter from EASUN worked in this configuration without issues for years. I had installed many of those inverters and this is the first one having this kind of an issue. EASUN engeneer is on this but can't seem to find what the issue might be. Already removed the SCR (parallel) board as part of the diagnosing process, disconnected all the loads etc, but nothing helps so far. If all fails, I will have to consider re-wiring the house installation, but that is really the last option, since the inverter itself should work in this configuration without issues.

You have by this model no neutral!!! Nehme den output neutral vom input ab!!! Dann funktioniert es!! Die neutralleiter dürfen sich NICHT BERÜHREN BEIDE!!

Hi, thank you for the suggestion, but the output is already set to 230V and 50Hz output, but as you can see from the video, has some issues when input AC is connected to grid, and the grid then goes off(simulated by disconnecting the live wire, but neutral remains connected.

Well, the fact is, it will work if you pick the slicing settings in certain way. However, do not rely on it doing so with out-of-the-box firmware settings. It will sometimes work properly, while in other cases it will simply stop printing at random stages of print and go into a reset. I have updated the description of the video with instructions on how to resolve the issue.

Hi Tim, I haven't updated the situation after this video, but the issue was really resolved with the information provided by Tronxy support. Namely they suggested the same thing that you mention (format the SD card), plus some additional things. To quote the email I received: 1. Format the SD card, and then print the test model to try. 2. Re-refresh the configuration file. Pls check and update below firmware, load these file into sd card, use machine print the gcode file below to finish update, then re-start the machine. 3. Use other slicing software, and do not center the model when placing it. After formatting the card the things started getting better, and the advice to not center the object on the bed did seem to work as well. But the configuration file they supplied helped most, as after uploading it to the printer it never did go into reboot again(I can send you the configuration it they haven't supplied it to you already). All in all, I am quite pleased with how it works now and have printed more than a couple kg PLA, TPU and PetG filaments so far. Retraction is a bit tricky to adjust to work perfectly as the bowden tube is really long, but it is tolerable. I hope you will get yours to work fine and enjoy the prints as well.

@@IgyBoyCRO thanks a lot ! i have the same issue.
