8kwt аксіома працює на прошивці від 10квт моделі, але значення які видає інвертор при навантаженні не відповідали реальним і були завищені, але по сонцю 5квт інвертор вибирав. https://powerforum.co.za/topic/24190-new-firmware-for-axpert-max-ii-10kw/page/2/#findComment-203572

@Coulomb hello, do you had a chance found variable for MPPT power in fw?

Thanks, I will waite

82.63 fw on 8k model works fine mppt took 5к from mppt1 & 2к from mppt2 My panels setup is only 7k in total & I thinks it is save increase limit from 4 to 5k for mppt 1 Noticed only issue with load values on that fw it report 25-30% more than actual Now, I am rollback to 281.05. Coulomb It is possible change MPPT1 limit from 4k to 5 k for 281.05 or move mppt part from 82.63 to 81.05? Also MPPT algoritm on 82.63 works better that in old version & it great. Thanks, Denys

Now, I am already flashed 82.63, tomorrow I will se how mppt works on this fw tomorrow, now it cloudy, & am sure that it can easy take more than 4k from one mppt, in manual for all these inverters values for voltage & current the same. I want take more than 4 & less 8 from sun in total, & not more that 8 from AC output

Hi Coulomb, could you please created custom fw for max ii 8kw? Now inverter on 281.05 fw, inverter limit mppt at 4k, I have 2 strings 1st 4680w 419 VOC 354v on max load 13.24 A panels, on the second mppt I have only 2.2k power. Looks like MPPT for models 8kw , 10kw, 11kw the same 90-450v at max power, 500v VOC & max 18A. Hence for me looks that on 8k model power limited by fw on 4k & for 10-11k model 5k per MPPT Could you please replace MPPT part from 82.63 to 81.05? In total will not generate mp than 8k, but allow get 700w when sunny

With 281.05 in brik state uploading not starting sometimes was error in Arena flasher, but with 82.06 uploading started, noticed that 82.06 fw size for 22k lager then 281.05

My axpert vm II 8kwt win 28066 chip bricked during upgrade from 81.03 to 281.05 I am able recover it using fw from Danilo MAXII_10K_82.06.inv , inverted flashed & boot up then I am updated again to 281.05 inverted successfully flashed & no more 90v issue. Thank you Danilo & Coulomb
