The Seplos 14s is for NCM chemistry only as far as I am aware?? I could be wrong though. From my brief chat with REC last year the BMS can be programmed at the factory for different brand inverters.
seplos support a compatible pylontech canbus protocol, use by most inverter with canbus protocole, they also have specific protocole for growatt and other. just call them for confirmation.
this document describe the bms intercommunication , not the protocol expose to the inverter.
NO mppsolar don't support CANBUS on any of their inverter . mppsolar support only RS485 BMS protocol. that been said your inverter will work well without having a BMS communicate with. everybody use to do like that for a long time with mppsolar inverter.
They say they do, but my inverter is complaining "BatNameFail" when set to Pylon. If I set it to user-defined it works, and reads the CAN properly.
they now also have a rs485 version, which i and some other members have recieved for testing.
What settings do you have for user-defined? I got seplos connected to Solis RHI inverter and getting same error 'BatName-FAIL'
I've left it at defaults for now, basically because I don't fully understand the settings and my battery hasn't had chance to fully charge yet anyway (not much sun these days).
Thanks. Got it runing with user definied settings. I just tried to match them to my previous setup that I had with pylontech batteries.
Can you take a photo of the user defined settings for me please? Thanks.
Here is what I got I would say the protection voltage should be tweaked but I am not to woried about them as BMS should be able to handle them and protect cells.
Looks like you are running the same inverter as me, I have the 6k unit and my settings are identical
ah apologies, I misread what you were after. It uses the pylon protocol which i'm not sure is officially documented
I asked Reklamos because I have the 5K unit, and I've set the current limits to 100A (just over 0.3C on a 280AH pack). His limits are set to 60A, so unless he's running a small pack or a 3K unit, I think those are too restrictive.
Mine is also 5kW, the limits are for 60A because mine can only charge/discharge at 3kW max. 100A would give you 5kW charge/discharge. My inverter is older 4G, the newer 5G ones are rated at 5kW for charge/discharge.
Solis RHI 5G 5KW hybrid inverter and a 200A Seplos BMS.
Maybe its a limit of my 100amp unit then,
You have set the limit on both the Solis AND on the BMS with Battery Monitor?
Solis is set to 100amp and the BMS only has a setting for over current protection and not a charge rate that I can see.
In user defined mode, the canbus is not use, the inverter just sense the voltage of the battery to monitor the charge/discharge. BTW which inverter are you using ?
We both have Solis inverter. I have also set to user-defined as it does not work otherwise. Looks like Seplos is not providing or providing wrong name to inverter. According to Solis CAN protocol, name is at 0x35E. I'm just wondering what Seplos has set at this address.
