Just a quick follow up. After several days attempting to figure out what the problem is, I finally found it... The reason for the inverters shutting down is clear: the BMS entered low voltage alarm state and doesn't allow any discharge. I need to play with the settings to prevent such deep...

Hi all. Please apologize in advance for the long post. I set up a DIY pack of 16s3p EVE 280Ah EVE Lifepo4 cells, with a SEPLOS (V1) BMS and 2 Growatt SPF 5000ES inverters in parallel single phase @230V. All worked fine since day 1, with a "particular" detail: the solar panels are not available...

My Seplos has no BT so I only used the PC version. It works like a charm with the Growatt inverter by choosing the pylon CAN protocol and L52 on the inverter. I did made the communication cable myself, by just using the 2 middle wires on the RJ45 on each side. On the SPF inverter you will know...

I understand but that makes little sense in my opinion... 64A at single phase from the grid is not even allowed in Europe (at least not in Portugal, max is 45A). Over 10,35kVA one must go 3-phase... That's not what want to do. I don't want the inverter to "assist" the grid with power from the...

I installed 2 parallel growatt inverters with a Seplos BMS and a big pack of 280Ah EVE Lifepo4 cells. All is working fine and the inverters were really easy to set up (apart from ShinePhone, what an idiot setup...) There is however a point where I think the inverter is missing a basic...

Ahhhh didn't got that info before, sorry. Then yes, it becomes a "silence treatment" :( Other than a "friendly reminder" I don't know what else you can do, overall it's impossible to force an answer from them. Good luck

Of course not... TBH I'm used to getting these kind of replies, regarding the most varied products when you are attempting support from Chinese suppliers. My conversations on Aliexpress are sometimes hilarious (not in a good way...) Also I just exchanged some emails with Seplos and they admitted...

In theory you shouldn't need any balancing after a proper top balancing before going into operation with LifePo4. Nevertheless if you do want to have it then the more current, the better. The maximum current is only used when the difference between cells is very high, so it can also provide low...

Actually their justification is plausible... EMI is in fact "a thing", not sure if it can or cannot cause your problems (I don't really think it does), but it would be easy and cheap to do what they say. If you are using standard RJ45 patch cables get one with metal connector and shielded cable...

Hi all. I recently assembled a big 16s3p pack using 280Ah EVE LifePo4 cells, which translates to ~~40kWh, 840Ah. I'm using a single 200A SEPLOS BMS, not sure which version it is (but it's not V3 and it does have bluetooth). I had great success with this BMS before and the communication with the...
