So i can go maximum 12P the distance is around 50m of cable 6mm I will try that if it works then i have to buy 1 more inverter to be able to use all solar panels

Well thats what im using and still got the error. I will try 8p on sunny day.

I have atached a photo with infos about it. I do have 32 solar panels 375 longi solar panels. What is the best setup to use them?

Well the voltage its in the limit, 280v but there might not be the amps. The solar panel produce 10.8 amps max, when i use 8ps2 i might get 21 amps, when the limit is 20a far as i know for this model.

I forgot to mention, that if there is no pv input, the paralel works very good, no light flick. Each inverter has 8 solar panels (380w solar panel) in series, and the 8 solar panels are connected on paralel with another series (total 16 solar panels for each inverter) So its 8sp2 for each inverter, i did something wrong with pv input? Only when its sunny outside the lights flicks

Well if i use only one inverter everything works perfect. It doesnt matter if is inverter 1 or 2. I will try to switch the.master but far as i remember i allready tried it. The ac out wire (aprox 1.4m each) goes in to a breaker where both N and L connects on that mai breaker. I have repleaced the breaker. Still the same problem. After the main breaker (100A) breaker, it goes on to the mail table of breakers.

i am only offgrid, i dont have any ac here. u cant see the error cuz didnt came in, if i was waiting a little more the error would popup. Yes the fault code its 72, current sharing. i have checked all the cables, replace them the red and black twisted one. changed even the vga cables, parallel boards. Also changed 3 times the ac out cables. they are same dimmensions and thikness for both of them (maybe 1 cm max difference.) what do you mean by daisy chain?

Here you can see a video with the problem!

@Coulombreplaced the parallel boards firmware U1 52 29 The problem is still there. They are original boards from EASUN website the inverters are hybrid 5kw when its sunny outside (one inverter have almost 5000w pv input) other one have @ 3000w pv input, the voltage start to fluctuate from 230 to 215 etc. I got no ideea what the problem might be I might have to sell them ...

@Coulomb i mean i got something like U1 11 Etc . @Beat Tomorow im gone replace both boards.

@Coulomb i got something love U1 11 etc

@Beat allright im gone order another boards

Hi there. I have two inverters EaSun iGrid SV II 5kw and im getting error 72 all the time when its sunny outside. After my research i found out that i need to update the software. The problem is i havent found any software on the internet. Also then support from easun its not even answear. Can you guys help me with a firmware for this type of inverter? I know that software from mpp solar also works with easun.

Well i am using the original cable that they gave me. From there i use this https://www.emag.ro/cablu-aten-usb-to-rs-232-adapter-35cm-uc232a/pd/D47K07BBM/ adapter. Using this adapter i can read data from EaSun inverter. The problem is that i have EaSun iGrid SV II 5kw not MK II :-S And yes, i have changed the COM from COM1 to COM9.. all of them..

@Denarius any ideea?

so u didnt find a fix for Can not open serial port ?

Hi guys, when i try to flash my EASUN 5kw MK II hibrid inveter i get an error "Can not open serial port" . Any idea how to fix it?
