Signature told me not to update the firmware as they have described numerous complaints about issues after firmware update

Yup. I got three battery packs from Rosen and two of the seplos failed due to the bad diode and they sent me all replacement and even a spare for the third unit. Suggest you talk to Link at Seplos. Dm me for contact info if you would like and just to mention I am way in Jamaica. And it was sent...

Ok I’ve been reading your comments guys. USE is for non BMS batteries and USE2 is for batteries with BMS. The reason you cannot change the 19,20 values is when it is configured properly it will default to a 16s setup which is 54.6 for both values I think that’s the setting. If you CORRECTLY wire...

Yea I know they logged in this morning and upgraded the firmware on my three units and it’s been hell ever since. Which bms do you have ? 10D or 10c

Did a sketch diagram hope this helps with all those BMS Error 20 codes

There is a video to show this .

Speaking about the idle consumption, do you guys know of an inverter that makes a lot less noise than the growatt transformer base inverters? I have a SPF6000DVM and it is LOUD.

I’m on use settings.added my Outback FM80 with 2700w of panels to help in these overcast days having now. Working perfectly . Monitoring with battery monitor to the Seplos bms x3 and direct usb cable to the inverter with PVkeeper v.2 to the inverter. Bought Solar assistant and just waiting on my...

Send some more info

A bit more detail Please. Battery dip switch setting ? Master and slaves or just different addresses ? And Changes to setting on inverter to say indicate you wanna communicate via canbus?

As in call Seplos?

This I would like to know as well

Just came off video call with Rosen battery co. And they fixed the bms communication between batteries with Seplos bms and inverter communication to show correct SOC.

Here is SOC showing correct at 49-50%. It’s 6 am so no sun up yet

It is a different cable config for bms port on growatt to battery bms/canbus port. Below is cable config. I know it is said to be a cross cable but this works with no error 20 when now selecting setting 5 -> LI -> 51 -> L01 Blue and white /blue /green and white /orange and white /orange /green...

They just replied so will see

No . It works with others as long as bms is compatible ex Rosen batteries work .

I’m lost as well with this response

Can you explain this more? How could you ever use a regular patch cable that is standard Lu straight thru to get communication ? Only unless it’s a standard cross over cable then I may get it but not a regular straight they patch cable

Ever found a decent switch for the 48v+ system

Hi guys , recently got a new sw4048 that will not seem to work with my combox. I loved this interface with my sw4024. Is there a solution to this via firmware upgrade or downgrade to sw4048?

Question do you find your spf6000 fan very VERY noisy and constant reguardless of load? I’m running at average 650w even at night and the fans are really very noisy. I’m wondering if something is wrong or what? It may stop for about 2min at times or a min and then just start at full fan speed as...

I am in same position but I will go thru with it based on the fact that directly and indirectly I am speaking to the same person Cherry from Rosen so the money is going to same place so I will try it out .

I have the same setup. Link me

I have 10d bms boards. I use canbus to growatt bms connection with Li , L01, 51 settings. Cannot use straight cable for communication . Gives bms error 20. Have to use the 1-2, 2-4,3-6 pin connection cable and the dip switch setting are on canbus with master set to 0, and other two batteries set...

How did this work for you? My sw4048 did not work with my combox

Please don’t do that. Sorry just seeing this forum and it took me about two months to figure this out. As I said msg me when you can

Also what’s the file name of the update firmware they sent you? Want to make sure I don’t do the same thing

Where is the buy and sell section in here?

What does “ SOL with a CAN board”? Link just told me the bird I have is RS485 even though it says Canbus. Need some clarification with you guys experience.
