here are the charts from last night and this morning and and the comparison between Solax and Aexpert

Hi everyone and Merry Christmas I am back with graphs related to QFW 556.05 for the last 2 days, yesterday being dark, a rainy day and today being predominantly sunny. I saw that I no longer have voltage during the night at MPPTs. I also put a graph with the comparison between the original firmware 56.02 and the custom firmware 556.05 I continue monitoring custom firmware . Thank you all for the hard work done to obtain the best possible firmware.

bearing in mind that with the original firmware it was stuck at 90V in bad lighting conditions and had to be manually reset or exceed the current from the panels by a minimum of 0.5 - 1 A per string to start producing again and jump from 90V to ~320V, we were losing a lot of production per day sometimes on cloudy days and up to 60%-70% compared to SOLAX which I monitor and which has the panels a little worse arranged, 5 are on the west and the rest on the south and for me they are all oriented to the south and without obstacles for now I say it is a huge improvement! thank you !

Condition verry low sun, and rain condition Pic 1 : Voltage MPPT 1/2 Pic 2 : Curent MPPT 1/2 PIC 3 : Power MPPT 1/2 Pic 4 : Solax Inverter with same PV Power but a little more badly oriented about 5 pieces L.E. : I confirm the MPPT don't stuck for now, I don't have to reset manual and the production is "wow" for this condition when the MPPT are stuck to 90V !!! The my manually reset will last 20 second and then the MPPT are stuck again to 90V !!! This is a werry improvement in the low sun, the only thing left would be the "production per night" ! TX for the hard work, Coulomb !

Very low 🔅, rain condition

Hi, I flash ultimate firmware 556.05 and this is the grafic on dark night. I can wait to see in the light condition

Hi, you don't have the 90v bug on your inverer ?? Can you upload here the firmware?

I can't wait to test it, TX for the hard work!! My setup is 2 string on 375w * 10 pic's Canadian Solar and 25Kw li ion battery Nissan Leaf with Orion Jr 2 BMS and Victron Smart Shut for monitor the pack in solar assistant

Yes, factory default firmware version 56.02 and unplug on grid with full house load Were is the spike i reset the mppt manually on both

I will waiting from the next patched firmware from you or Georege ! TX !!

here is voltaj on MPPT1 and MPPT 2 , on both of them is identic 10 pics of 375W Canadian Solar PV, both strings on south

Hi, main CPU Firmware version 56.02 (U1) Secondary CPU Firmware version 22.10 (U2) 0000 (U3) the unit is bought from november 2021 and YES I HAVE STUCK ON 90V ON PV1 AND PV2 ! I have 2 strings of 375w * 10 pics of Canadian Solar , Halfperk Cut Here is unboxing TX

Hi Coulomb I have an Aexpert max II 10 Kw from SolarPower24, can you please tell me what processor I have and if I can flash your firmware, thanks
