i have chooser the [DE] VDE-AR-N4105:2018 storage >4,6 kVA, now when use more than 5kw from batts get this error any idea what could be the cause ?

any idea how to have readings in Volts instead of "p.u" ?

update chart

4600W is due to regulation of max 20A on a single phase (in Germany called Schieflast avoidance) - not sure if this could be changed by other country settings.

Found it :), done thanks.

Offtopic, do you know if importing solar panels from china is tax free ?

Hello everyone, so the system is running fine, i notice SI is limited in self consuming ! To get more Watts we need to go offgrid !

Case to study now...

BTW i have order an serial splitter to try plug the rec monitor and Bluetooth, once Rec Bms once has one port, will see if works

Very good - thx for letting us watch the progress and the hurdles you took exceptionally well.

Thanks but you was my inspiration to get courage to do it so I thanks forever your share, working and help, many many thanks !

Note: all my knowledge has learn by internet/youtube in recent 10/15 years , even speak and write English !

System is ok now just need to put same 7/7 batts on last parallel for no stress BMS, until my sun tracker doesn't arrived i configurated in sunny portal on system proprieties-parameters there is a option that you can use an period of time and choose what W you want to charge, exactly what i was looking for, well again many thanks for your help was precious, when i have a good chart will share it, regards.

After re-doing Installation assistant these setting need to be off, now is fine, next step is limit the use of battery during a period of time because once i am bi-hourly grid contract i would like to "protect" the batts so anyone knows where is the setting of these ?

midnight update soc drops to 3% and cuts batts, now for my suprise when started SI he started to charging batts, now need to control during night sleep

Hmm - I am blind how to export the settings to PDF?

Update, cell R 5 and 9 still high maybe need to unplug copper bar and plug again

i made a print from browser Ctrl+P(i access via browser ip not for sunny explorer), choose Microsoft Print to Pdf and is done

these are the parameters available on my SI, i have some changes on the generator to see if can find the bug.

until now is working great, only the cell resistance 5 is more high but like i said before is in the middle and the bolts are not so strong could need to be retouched...

Reagarding the Parameter for the SI I am completely lost now - I don't see any of those on my SI. I can also only compare with the sunnyportal. Sunny Explorer does not give me any annswer on config settings (need to figure out why).

@ALL: someone able to suport here?

Charging control should be at BMS - Maybe I am wrong but somewhere you can set the SI to LION so BMS is external via CAN. If the SOC displayed in SunnyPOrtal is correct your setting should be OK otherwise you would get no values.

Regarding the resistence I did not get your question.

i access to my si via ip address, i put an old laptop connected to lan and i can remote access to all parameters of Rec Bms and SI via Remote free program acess " Anydesk"

hello

i have one phase i should choose Asymmetric ?

here i have mains choose, don't know very well what mean "mains":

these setting shwould be for charge the batteries ?

cells 5 and 9 that was more resistance are in the middle should i be worried with that because i think the cells more important are the + and - ?

Big BIG Thanks for helping !

yesterday and today did the same thing at night did i miss something in install ?

I connect to AC2, i think the circuit breaker is correct... One phase

will took off the cooler and see if goes down, i did some custom cooper plate with thermal mass strange !

"Cell 5 and 9 I would monitor the resistance" these could be bad connection ?

cell 13 and 14 unfortunately i didn't get 1 gen1+gen2 extra modules they send me wrong 2 of the same :(, so the last parallel has 6 modules gen2+8 modules gen1, the other 6 parallels has 7 modules gen2+7 modules gen1, my concern is that the 13 and 14 cell can't reach the 4.1V or maybe is betther i lower max to 4.06V ?

PS. I put the 4.06V and they go 100%, now put again 4.1V, will see...

I have copy from your settings :), what you think ?

Now I have lots of new info to study !!!

For now system is running ok, i have deleted the plant and made one from 0, wasn't able to add the sunny island to the plant, any idea where are the settings to increase watts of charge because at these time i have around 5kw prodution ?

i think i now have made sucess, after press the island button for 10s. is on now i think !

the only bug i have now is add the sunny island to the plant is tell me no, but i have changed the pass, did you make a new one ?

correct not charging, something is missing i think !

here you choose 1 or 2 ?

thanks !

so now i just wait ?

I skip these step once is for acid batts right, now i see the sunny island but batts are not feed the house is these normal should i need to do any configuration ?

Sunny Island On too, did you 13.5 Performing a Manual Equalization Charge in the Off-Grid System when start the system ?

will try see what settings can do !:D
