Rosen Solar from Alibaba, anyone have experience?

[houseofancients]

Yes , per battery .little sun here today so unlikely to reach 3.45

would you happen to have grid or a generator ?
otherwise , given this is January ( and your dont live down under i assume) , it may take a whole lot of time

Yes I have a 6kva diesel generator, alas another problem there , the growatt inverters won't accept the charge ! Location is Kefalonia, Greece, 300 days of sun

 

[gramos100]

No grid

there are certainly worse places to be in
good luck on the charging and keep us posted

 

[Sanwizard]

disconnect comms, use USE setting on growatt .

alternative is opening the batteries up and using a labpower supply

Yup. I agree

It may be time to pick up a small inverter generator. Your diesel is probably not putting out an acceptable AC sinewave to your growwatts. Inverter generators are much cleaner from a total harmonic distortion perspective. I know my MPP inverters reccomend Inverter generators for the GEN input, as the THD must be under 10% for it to accept the input.
You may also want to get a power supply and a small LiFePo4 charger for maintenance. For the charger, I use these folks on Alibaba. GREAT support.

pensez-vous aussi filmer les écrans de batteries rosen en faisant defiler le menu ?
Et pouvez vous filmer les cables de communication bms, ainsi que la position des DIP d'adresse ?

je vous suggère d'essayer la dernière colonne.

 

[gramos100]

Bonjour merci, je vais essayer ces paramètres que vous suggérez et je publierai bientôt les paramètres du commutateur BMS / dip

 

[gramos100]

Bonjour,

Pourriez vous filmer votre installation, les câblages, faites afficher tous les paramètres de l'onduleur.
Mettez votre film sur youtube et envoyez le lien, comme ceci par exemple :

Nous pourrons peut être vous aider.

D'accord!

 

[gramos100]

Well I used all your settings and it just shut down what would you suggest?Eh bien, j'ai utilisé tous vos paramètres et il vient de s'arrêter que suggéreriez-vous ?

 

[houseofancients]

Well I used all your settings and it just shut down what would you suggest?Eh bien, j'ai utilisé tous vos paramètres et il vient de s'arrêter que suggéreriez-vous ?

open batteries , connect a lab charger to each individual cell, follow top balance procedure in resources section for each cell in all batteries

Bonjour,
quel est le code défaut de l'onduleur et quelles sont les valeurs de tension des cellules des batteries s'il vous plait ?
votre groupe électrogène est-il accepte par l'onduleur?

Bonjour,

fault code after shutdown is 56
cell voltages around 3325
generator has not been " accepted" ,
it will power the house but not charge the batteries

Le code d'erreur après l'arrêt est de 56 tensions
de cellule autour de 3325
le générateur n'a pas été « accepté »,
Il alimentera la maison mais ne chargera pas les batteries

I dont have a 230v charger capable of more than 30 amps and being off grid , it is not possible .
I am reluctant to open the batteries up as this will be a warranty issue
, that is if rosen solar honour their warranty !

you dont need more than 30 amps.
a small lab charger that goes to 30v and 10 amps will do just fine.
run a generator..

so how's rosen warranty helped you so far ?

Your generator is most likely not providing a good AC sinewave. Use an Inverter generator like a Honda 2200i.

[Jeromebricolo]

est ce que vous mesurez 50v en entrée de l'onduleur?

 

[Jeromebricolo]

Si oui, l'onduleur peut avoir un fusible grille d'après la notice growatt.

Abysmal !
They totally ignore me , for months .
My son is planning to buy from them as are 2 other friends and I have told them the deals will not go through until they
resolve these issues which have been a problem since installation , as they too are concerned about after sales help .
Well , well , a contact from them today !
Just questions as usual , what is the invoice number, serial numbers , etc, etc ,
lost count of how many times these have been sent.
Never a solution .

Thanks , but the generator is a small part of the problem and when the current problems are resolved
I will look at the generator in more depth.
It is a Hyundai 6kva diesel silent generator and was bought for the power supply for the house build .
If needed it can run the house and it would be great if it charged the batteries as well .
I,m sure you are correct it is not a pure sine wave output .
