SRNE HF2430S80-H (24v/3.3kW) 6.17 firmware

Welcome!

I looking for 6.17 firmware (battery version) for my SRNE HF2430S80-H (24v, 230V out, 500V PV, 3.3kW max out) inverter. I bought it with 6.63, later upgraded to 6.64 (got it from SRNE support - it support BMS perfectly - but i not really need that) - and i do not need the mixload function, so i would like to downgrade to 6.17.
Thanks!

Hello I have such an inverter software 6.63.. Tell us more about version 6.64. Can you send me this version. What you have updated the software with. Thank you for your reply

I bought it with 6.63, and before i used it, upgraded to 6.64. I got that file directly from manufacturer support. It support various BMS protocols, but i killed my Daly BMS last year (overloaded it with a stuck 2.5kW motor), so i was not able to try it.

My problem with the 6.64 firmware, that when there is low AC load on inverter (or no load at all) then it does not charge the battery correctly: it is fluctuates between the min the max (like a bad MPPT hunting) and stuck mostly at 40W. When there is suitable load on the inverter (eg 400w), then it is fine: supply the inverter correctly and with the rest energy charge the battery.

And when i enable the BMS support and there is no BMS connection, then it is feed only the inverter from PV and does not charge battery at all. (and there is BMS error) it is fine - i guess, with correct BMS communication it would be fine.

Here is the image file which one i got. Does not confuse you the name of the file, it is for HF2430S80-H.

Thank you for the software. As soon as the manufacturer's warranty ends, I will upload this software.

I downgraded it to 6.63 and fluctuating charging gone, working fine. So i DO NOT recommend to use 6.64 without supported hardware BMS.

Update:
I got meanwhile 6.53 firm, but that was not compatible with my unit (according to SRNE my device is newer - i got error 02, 20, 23 with that firmware).
After they sent me firm 6.68, where there is a new option [39] where the charge logic can be set:
- inverter smart logic (i guess it is the standard one, i have problem with that one with my LF09 setup)
- max current limit which was set in option [07]
- and BMS limit based charge
Theoretically it is working with BMS only (but maybe the BMS limit based charge only), but i try it without BMS soon - i hope the fixed value will work with this one.
This firmware support CAN and RS485 communication with BMS.

Hello your software 6.63 support CAN and RS485 communication with BMS. Here's my https://www.srnesolar.com/wp-content/uploads/2022/11/HF24-H-User-Manual.pdf . There is still a number 30 address Rs485 on the inverter, it is not in the manual
I have firmware 6.66 I have not checked.

Hello everyone, I am writing from Italy. I have a Smx 5.6 easun inverter which is the Srne hf4850 model, what firmware have you installed?

Hello your software 6.63

Hello 6.35
