Hmmm... sounds like a hassle having to use a pc/laptop on every client trip...Yes using the pc app

Are you talking about CAN1101[FW27-DFSET_GW02_NEW_210616] ?? Because i have same problem with my Growatt SPHSame for me. I texted one of their after sales engineers (Link Liu) and he sent me the Growatt specific firmware file which has already been posted on this thread as I see now. I updated the firmware set the CAN protocol to Growatt and it worked straight away.
I don't want to be a spoilsport, but I´m sure the BMS does this not, not the Seplos.The BMS will instruct the inverter to fully charge the battery, when there is a need to recalibrate (see pylontech protocol document for the details) . here is one more reason to have the BMS communicate with the inverter.
? the Seplos is the BMS.I don't want to be a spoilsport, but I´m sure the BMS does this not, not the Seplos.
More and more users who are writing with the technicians from Seplos and testing the BMS in all it´s functions come to the same conclusion: They don´t know how to charge a lithium-battery and the software and charging-algorithms are simply a fail.
oh wow..I don't want to be a spoilsport, but I´m sure the BMS does this not, not the Seplos.

The BMS is not supposed to know how to charge a Lithium battery. Its only supposed to be there as a failsafe to protect it. Its your MPPT charger that is supposed to know how to charge the battery.I don't want to be a spoilsport, but I´m sure the BMS does this not, not the Seplos.

Thats not true. Many bms are programed to tell the inverter how to charge a battery. My pylon batterys cut charge rates at different soc. That's not protection.The BMS is not supposed to know how to charge a Lithium battery. Its only supposed to be there as a failsafe to protect it.

My Seplos defo manages the charge, I can see the can messaging from the BMS to the inverter when I hit my target voltage and the charge rate drops from 100amp to 10amps.Thats not true. Many bms are programed to tell the inverter how to charge a battery. My pylon batterys cut charge rates at different soc. That's not protection.
were you setting the shutdown parameters ?Hi, can anyone help with an issue I have with my Seplos BMS? I was adjusting parameters on it and I lost connection. Now any time I try to start it up, it starts (LED's light up) for around 30 seconds and then shuts down.. Pack voltage is currently 52v. Any tips as to what could be causing this?
Yes!!! happened to me before! the firmware got corruptedHi, can anyone help with an issue I have with my Seplos BMS? I was adjusting parameters on it and I lost connection.

yes, afraid you'll need recalibate, but i wouldnt go to 3,65 a cell.Actually got another question now. Because I had to revert all settings this has messed up the total ah and useable ah. Should I just charge to full voltage @ 58.4v then set the pack AH correctly, then do a discharge to 10% @ 0.5c so everything gets calculated properly?
as microsoft used to say :Ok, thanks. Not sure if it's a bug with the software but I have to hit save all to save some settings but this then resets the Battery Rated Capacity AH and SOC AH.
I started work on " translating" the software, if you have a look there are two XML files called en-us and one under the agreement folder called 16s_v20 with all the weird Chinese oddness language, this is read in depending on what config file you loaded up originally. I have changed quite a few including the max and min voltages so you can actually see the cell differences rather than the truncated outputHa ha, yes that old chestnut! I think I have my top-end voltages adjusted right now. More by luck than skill. I still can't figure out when it decides 100% is 100% but it did eventually do this last night and then put the battery in to standby (while waiting for load) which is what I wanted. Will have to test this again on the next charge cycle.
Working on tweaking the lower end today. That battery monitor software definitley has some funny quirks. I'd love to be able to correct all the incorrect English words. Would make it so much easier to read!
that would be good...I started work on " translating" the software, if you have a look there are two XML files called en-us and one under the agreement folder called 16s_v20 with all the weird Chinese oddness language, this is read in depending on what config file you loaded up originally.

well the only way ( i know of) of recalibrating the soc is a full charge to a full dischargeHa ha, yes that old chestnut! I think I have my top-end voltages adjusted right now.
