The dip switch must be 1000 and Li must be 02 for 04. Also you must use the BMS port of the inverter and make sure that the rj45 with pin1,2 is on the inverter side.

No problem, we are there for each other.

Hello, indeed it would take a different cable that you can make or get help from a computer specialist, it is a crossover cable that you will need. just two pins are used: pin 1.2 on the inverter side and 7.8 on the battery side but crossed, i.e. pin1->pin8 and pin2->pin7. Best regards

Apparently your new inverter does not have a CAN port, so you cannot use the same Li 52 settings but rather Li 02 or 04 with the rs485 port of the Master battery with the dip = 1000.

Hello, Do you have an Rs485/Can hub for paralleling the communication of the two inverters? if not it is necessary, see the manual. Best regards

Hello dear all, could someone help me to better configure my system? it is made up of 32 pylontech batteries including 28 us2000 and 4 us3000c with 5 growatt spf5000es inverters old com card (ie 40 06, 41 06). As the configuration of the communication in rs485 does not allow to take the charging current of all the batteries, I therefore opted for the configuration in CAN communication mode. the 4 groups of batteries each have a us3000c as Master and a useful pylontech hub. The problem is on the one hand the hub indicated 3 groups instead of 4 and on the other hand I have communication errors several times with one or more inverters during the day creating an interruption for each code 20 error triggered. If someone has experience for the same type of installation to advise me. Thanks in advance.

Hello, can I have the software for updating my SPF5000ES inverters. my email address is: [email protected]

Bonjour chers tous, Est-ce que quelqu'un a l'expérience de l'utilisation de groupes de batteries pylontech avec les onduleurs growatt ?

You are absolutely right, I even changed inverters to the spf5000es version but it is the same problem in rs485 communication mode. In CAN communication mode, there is no load current problem but it is unstable (BMS error).

Hi dear, I have the same BMS error problem with my spf5000es inverters, so if you can share the software update with me. My email address is [email protected]

Salut mon cher, j'ai le même problème d'erreur BMS avec mes onduleurs spf5000es, donc si vous pouvez partager avec moi la mise à jour logiciel. Mon adresse mail c'est [email protected] Merci d'avance.

Hello dear all, I have a system with 5 spf5000es growatt inverters and 28 us2000 batteries in 4 groups with the communication accessories namely the hubs for the inverters and for the battery groups. they operate in parameter setting mode 05 = Li, 36 = L52. I had to restart already three times in 24 hours of operation. on the other hand in USE2 mode, I have no error message. In my opinion, it is the shutdown of the inverters which creates certain error messages. I am looking for advice if anyone has the same communication error and UPS shutdown problem and if there is a solution for it. thanks for any advice.
