Hello, I accidentally turned on the on/off switch function on this BMS and I am not able to start the BMS now while I do not have the button. Is it possible to just connect this two pins together to activate the switch?

To RSEE: 1) The voltage the Seplos BMS is wokring with is not suitable for the high voltage 3-phase Sofar inverter. But if it is pissible to use more BMSs for every 48V pack and then making a high voltage battery as mentioned in the second point, then yes... See Seplos web for more info. 2) No...

I have two questions. Did you contact the Sofar support? What is the inverter you have? I know the HYD EP series, but you mentioned the one you own is HYD 3000 ES. Is this your inverter? https://www.sofarsolar.com/product-detail/557/HYD%203000-EP

Ok. So you have ES series inverter, which is different to mine EP series. And I used mine only in offgrid mode. I will continue in the other topic.

Hello VVIRGILE, did you solve the problem? I cheched the error code ID005, ant this is charge leakage fault. So there was maybe some technical problem with inverter or BMS or wiring or something else... Restarting the inverter is also a good option to try.

If you have DIY battery with Sofar, Seplos BMS is the only way to go now, I think. I am testing one 200A version right now and it works very nicely, CAN communication works as it should when you choose Sofar in the Seplos CAN setting. You can set up all the parameters on the BMS you can imagine...

If it is not too late to asnwer your question, you can just configure the parameters for battery without communication system as written on the page 37 of the manual. And there is no setting for voltage disconnect or float voltage, just the DOD. I was using it this way few days till the Seplos...
