At one point, the warning 'Short circuit protection' appeared. It disappeared for a while and then reappeared. After that I turned off the protection.

I had a similar problem. I turned off shortcut protection in the Solar monitor app and then bms exploded. One FET burned out.. I replaced the FET and now it works fine. I would not recommend repeating my procedure because the PCB on the BMS could have burned. Maybe, you can try to replace the...

Thank you, but @deonbez says : RS485 BMS 1/2/7/8 : Not connected 4: RS485 A (called RM485 in manual) 5: RS485 B (called RM485 in manual) 3/6: GROUND

Thank you.. I will try today. Where I can find particular documents. In my documentation I can't find text with 'RM485'.

No, this does not work..

I have two battery packs and Seplos BMS-es. One battery is 200Ah and one 50Ah. I have a Growatt inverter with RS485 communication. BMS-es are equal (16s, 100A and RS485 - not CAN). One BMS is connected to the inverter and the inverter recognizes the BMS and all work correctly (all switches are...

Some Hybrid inverters do not have any option for setting anny parameters for charging. Just an attribute for the type of battery. Example Growatt SPH has only an option for Litij or Lead Acid battery. In this case BMS-es communicate with the Inverter du decision when it is time to stop charging...

What is the final result? You get new BMS, just connect and all work normally?

Hi, with my SPH4000 I got a CT sensor with RJ45 interface. Does anyone know which pins on RJ45 are active?

Yes, I solved my problem with this parameter.

You must check tri think: - In option 'Load first' you must have a setting for the lover limit for discharge. When BMS reported to SOC below 10% then the inverter immediately started to charge from the grid until 15%. Inverter will stop to discharge when SOC is 15%. - If the battery is...

Hi, You are a big optimist. Growatt supports only self.

I have SPH4000 and use zero export. That option works but not well. When solar energy is enough for load and rest goes to the battery, then import from the grid is about 40-50W. When energy from panels is higher which uses load and battery, and battery is under current limitation, export to grid...

My friend, I was talking with Seplos and I have firmware for my inverter. Pylontech .. Yes, now is too late..

Growatt SPH4000, Model:A0B9D0T0PFU2M457

Growatt SPH officially does not support any battery except Growatt. I have had a conversation with Growatt for the last four month. Maybe another type of Growatt inverter but SPH not. I am definitely disappointed and must find another BMS. Investition on the inverter is too big and for me to...

I don't know ..

Hi, I have contact with Growatt and get next response: 'Sorry, since the BMS and batteries are not from our brand, we have no such support of them. And we have no communication protocol of your batteries and BMS. They won't work successfully with our SPH. We cannot help you more about this...

Hi, I have Growatt SPH4000 inverter and LiFePo4 battery 200Ah with Seplos BMS. I have one big issue with BMS or with the inverter. My battery is fully charged but the inverter does not stop charging. The inverter is set at the end of charging (example 90%) but the inverter continues to charge...

Hi safikhanfar007, My inverter and BMS works with firmware CAN1101[FW27-DFSET_GW02_NEW_210616].ehex . Please, do not follow me .. You must get firmware from Seplos. Uploading the wrong firmware is dangerous and can destroy BMS. One when uploading wrong firmware it is not possible to upload new.

Hi houseofancients, Which version of firmware you uploaded . Which version is on your inverter? My version is RAAa209805 and communication ZCBA-0005 and I have the same issue like comtel.

Don't worry.. I got the same tracking and received BMS without any issue.

What is the exact issue? Have you Seplos BMS with Modbus or CAN protocol?

How can I limit charging on the Seplos or Growatt? I have SPH4000 and i cant see an option for charging limitation.

My inverter and BMS works with firmware CAN1101[FW27-DFSET_GW02_NEW_210616].ehex . Please, do not follow me .. You must get firmware from Seplos. Uploading the wrong firmware is dangerous and can destroy BMS. One when uploading wrong firmware it is not possible to upload new.

Thanks, it is a problem with the wrong firmware transfer. I did upload firmware for the CAN version, but BMS was for the RS485 version. After that, it was not possible to upload Growatt firmware for CAN but also for RS485 port. Seplos sent me a new BMS for free and now it works properly. Yes.. I...

Same issue I had. I opened a case to Growatt support which uploads new firmware and now i do not have a problem.

You must charge the battery with a charger to limit when BMS stops charging. Then must discharge the battery to limit when BMS stops discharging. In the meantime you will get some warnings. When the battery is empty (BMS stopping to discharge) BMS will self calibrate to capacity. The data of...

Yes, I have communication over CAN. Communication is with pins 4 and 5. I was also uploading new firmware which I got from Seplos.

In this case, why is this option available in the program?

Does anyone know what the calibration 'Voltage calibration' represents in the Seplos Battery Monitor app?

I also get information from Adam about hacking mail.

I accept, It is not a problem from Seplos, But... BMS sends messages to the inverter with battery voltage. Maybe, Seplos have the option to send in MODBUS data voltage of battery for 30 mV smaller. In this case the bus voltage will be smaller.

I have an issue with inverter SPH4000 when not having solar energy (overnight). When the battery is discharged to defied SOC (in my case 20 percent) then the inverter must stop using energy from the battery. In my case stop using energy. But.. inverters hold voltage (Bus voltage 30-40 mv higher...

Yes, now working.. Thanks
