I’m sure I can help but not understanding the full issue. Need some more info but it sounds like you are overcharging the batteries to an over voltage level which would shut them down as well as the inverter. Which Rosen battery do you have as in the model number? Is it 15c or 16c? Is it power wall penlight AA design batteries or lion ups design batteries inside the unit? Which Growatt are you using? How many panels connected to charge controller. Integrated cc or all in one hybrid? Need to start there
Rosen Battery with Growatt SPF 5000ES (BMS ERROR)
- Thread starter Pietskiet247
- Start date
I have had this shutdown issue ever since the system was installed .
Many , many conversations with Rosen but never a solution .
There is plenty of power and it runs fine until the batteries are full.
It is fitted at a new house build so usage is tools only , we will move in soon and I am hoping that more demand on the system will keep the batteries at less than full ?
There is a pool pump running 5 hours a day at the moment but the draw is not enough to prevent batteries acheiving full status .
I dont know how many people are reading these Rosen reports , but it can,t do Rosen much good to have their products discussed in a negative way ?
One thing I am considering is to disconnect some of the panels to lower the charge rate
any comments ?

There are 3 x Rosen batteries and they don,t shut down , only the inverters do this .
Sorry I dont know if 15/16c ? how can I tell ?
14x 400 watt panels , in 2x strings one to each inverter.
always in full sun , 2x Growatt SPF 5000 /5500 inverters..
Software version 907/909 , not certain of this , I will check today .
Ok what have you set the charging voltages to in setting 19-21? Are you paralleling the two inverters or seperate systems?
www.meritsunpower.com Meritsun battery welcome you
1. Can you confirm Meritsun is working fine with Growatt SPF 5000 ES ?
I saw some other opinions in this foum but can't qickly find it !
2. are you from Meritsun: if yes what could be the price for a 10kw DDP to Spain ? But only if question1 is answer is Yes !
tks
I hade a conversation with kenny lee (Meristun) and wanted Just to inform everybody and save your time that the MOQ (Minimum ) is by 6 pcs and so not interessant for most of us as end users !
Let’s work with one single unit.
Seplos BMS-Diode 4 defekt
Hello,
I had a Rosen 48V 100Ah powerwall with 16 cells and I could connect the BMS successfully with the Grawatt SPF 5000ES with "03" in the Grawatt setting 36. Here, I had to change the communication protocol of the Rosen into "Growatt" with the help of the Seplos BMS managing software installed on my PC.
Later on, I upgraded the system and replaced the old Rosen 16C powerwall with two 15C Rosen powerwalls (48V 100Ah) and added another Grawatt SPF 5000ES. Before connecting both inverters in parallel, now I'm trying to connect the BMS of one powerwall with one inverter to test the connectivity. But, unfortunately, the new powerwalls have a different BMS and it's not a Seplos. This was confirmed by the Seplos as well. (Please see the picture attached). And obviously, the Seplos BMS managing software does not connect with the battery BMS even though I change the settings.
Moreover, I'm unable to open the case of the powerwall to check the type/model of the BMS as it will void my warranty. But I dought that as in my previous powerwall, I will have to change the BMS settings (communication protocol) to establish a successful communication between the BMS and the inverter.
Has anyone could connect the BMS of the Rosen 15-cell powerwall with the Grawatt SPF 5000ES?
If anyone could help me, that would be highly appreciated.
Many thanks.

Hi Agmills,
Could you please sent me your settings?
I have 2 Rosen 200ah batteries and they are working but not without problems.

I bought my Growatt from them and I'm having the same problems. I already replaced the BMS but it's still not working right. I am thinking of using a different kind of BMS because the one in the Rosen battery doesn't seem to be working properly. Any suggestions? I have heard good things about the JK BMS.
I have 15 s Rosen batteries and need to tell the inverter this , it thinks the batteries are 16s , hence the issue

I bought a complete system from Rosen, including a Growatt SPF6000T DVM and a 48V 15S Rosen 200 AH Lifepo4 battery. The manual says communication works with RS485 but it only works with CAN and then it doesn't seem to work for too long. At first Rosen's support was fairly ok but then they started taking longer and longer to respond and then they simply ignored me. Anyway, with the help of the users of this forum, I learned that setting program 05 to USE and setting the voltages was the best way to get it to work half decent. I can't say I am overly happy with the Growatt or the Rosen battery but they are working ok now, I don't get faults all day long anymore. One thing that I think it is important to consider is wether your battery is a 15S or a 16S. The voltage to charge a 16S fully will cause an overcharging error with a 15S and the safe cut off voltage for a 15S will be too low for a 16S, so keep that in mind. Especially if you get errors 03 and 04 often. Regarding the communication, i got it to work with the CAN but it didn't work properly, the battery was returning to grid with over 80% SOC. I know the battery still had a lot of power in it because you can see the cell voltages on the display and they were sometimes above 3.3V. Are there different protocols when you use the Li setting for 15S and 16S batteries? It would make sense for them to have different set points but the manual doesn't tell you anything about that, if I remember correctly.
