For still suffering the Sepols BMS with Solis Inverter alarm issue which causes the inverter to report OV-VBatt-H when the BMS is reporting 100%, I finally have a solution! I spent the last few weeks talking to a Seplos tech who has been very helpful, trying out lots of different fixes. We...

As I stated in my previous post, the BMS requests a continually lowering charge current from the inverter as the pack reaches it peak voltage, all the way to 0. If you are concerned with the battery switching in and out of charge state as it floats near 100% you can turn off the BMS...

Suitable for all Seplos current ratings, but only SMA, Solis & Victron inverters

I have just built a battery cabinet with a Seplos BMS, powered up but I do not have a USB-485 interface yet. I understood that the Seplos shipped with the default Pylontech profile, but when connected to my Solis inverter, set to Pylontech battery it just reports Can-COMM fail. Same error in...

Did you ever get this working with the JK BMS?

I’m UK based with a Solis 5G hybrid and looking to add a self-assembled LiFePo4 pack soon (planning 16S 200ah) and looking back through this thread I can see the following options: ZEVA BMS - works but discontinuing support Seplos BMS - works but requires the Solis ‘user define’ option which...

Thanks, that’s good to hear. It was the user defined battery profile which Solis states in their manual is not for end user use which was bothering me.

Thanks for the help, I can confirm that setting the BMS to Sofar and inverter to AoBo and it has magically sprung to life. Next issue is that Solis cloud reports my daily energy usage and battery usage in the megawatts… does anyone else have this problem?

I’ve been running this for a over week now and it’s (finally) working flawlessly.
