I understand. 91.04 and 92.04 are the only ones that can reflash them, I was wondering if it would be possible to modify these versions. The idea is that 91.04 and 92.04 work worse than my 72.03, in the sense that to start the voltage it needs at least 3A per mppt, 72.03 needs 1/2A. Would it be possible to modify 92.04 to start the mppt at 0.5A alone?

Coulomb, thanks for the info. But how do we solve the problem with voltage blocking? The official firmwares do not solve, nor the ones received later. Probably should a firmware with a patch?

probably due to the fact that easun gave me firmware directly from voltronic, it's a good thing because 1. it assumes this firmware and any problems that arise, and 2. it's not a clone. I talk to easun through Anna oe whatsapp, she deals with sales on alibaba, and offers support only to those who buy through her. I don't want to do qboot...maybe I'm doing other stupid things. We are waiting 60 days, I hope nothing bad happens, but even if it does, there is probably a reflash or downgrade solution, Coulomb or George can explain it to us.

Sorry, 90.14 i couldt flash, only 91.04 and 92.04 from the voltronic link. If i will have F09 cauze the firnware...how can solve it? Is there a procedure?

http://ftps.voltronic.com.tw/E/Easunpower-93CB312922AC474787C6/ Here is the root of voltronic site. 2 firmwares for 8K, twice for 8K, if easun gives me from voltronic i hope is not a clone and wont be problems. What do u think ?

No,i dont have 60 days since flashing. It could be some problems ??? If i will have error F09 how i solve it ?

I dont have a link, is with other firmwares...but cant switch the tool with the same dsp.hex...will brick it

Must tell u that on Easun Smw8k i could flash only with Arena Flasher tool, with Reflash Tool X Series, didnt work, block the process after open the port. Dont know why

Sound good, do u think i can flash it on Easun Isolar smw8k ? now i have 72.03 firmware. I could flash 91.04 and 92.04...not bricked it. Thanks

I have easun smw8k and its not a clone, i could reflash 90.14, 91.04 and 92.04, worked...but the same problem with mppt voltage. Waiting for a good patch.

Hi everyone, i have the same inverter easun isolar smw8k, i already tried the versions of firmware 90.14, 91.04 and 92.14, all i have from easun, downloaded from a voltronic server, that conclude that is not a clone. All the firmwares have the same problem with the mppt in the morning. George, if u can make the firmware not to put the pv in short from the 1st second of light would be superb. That what sais coulomb is true...what can we do.with whis problem? In Romania we are a lot of people with this inverter....we are waiting for a sollution...thank u
