Hi don’t worry just update both inverter to the last firmware I have uploading here in forum and they will work fine no issues. main cpu 50.13 secondary cpu is 19.16

Hi in this a new update for expert king ll (5048 mkx) there is all time a current consumption around 1.78Amp and some time around 2.1Amp from battery this current consume from battery all time with utility or not with load or no load so my battery discharge and again charging after couple hours is this okay?! Note iam using pylontech protocol seplos bms

Yes . I agree but last update for removable display firmware on website for canbus protocol with version 2.83 really I don’t know updating again 19.16 or still with 2.83!

this last update from mpp solar 5048 mkx to fix issue (f80) with pylontech (parallel opertion). 5048MKX_STANDARD_50.13-20231201T112659Z-001.zip

Hi after using pylontech protocol I have error F 80 in my inverter expert king ll parallel operation this error happened in each morning and each two days in the same time I know it insane to believe also I see different in time in both inverter about 8 minutes after I setting both inverter with exactly time after that couple hours I see different in time between them!! If this related? I don’t know

hi i have bms seplos and i tried to contact bms with my inverter expert king ll (parallel opertion) through pylontech protocol and i connect with communication wire with master inverter and both inverter battery icon flashing but the second inverter still with led flashing and error 61 but it works and battery flashing but in same there is error 61 and red flashing so anyone can know why this happened or I need canhub or something or program issues?

Hi, I have expert ling ll (PIP 5048 MKX) with last version , main cpu 50.09 my issue is with mppt is not stable its suddenly dropping to zero or minimum power during load stable and full battery. my question is any one have another product PIP max or something else having the same issue with mppt ?

Yes . This issue very annoying for me you see Mppt suddenly drop to zero and rises again in this moment effect little on output

Hi everyone, I want to share with all people who want to buy from MPP solar Or voltronic inverter in fact no difference that’s Mppt built in inverter it’s working badly when battery float stage and when your loads running if PV power becomes equally to load Mppt fails to continue powering the loads also if your days partially cloudy ، When the sun appears and disappears between the clouds each time Mppt here disconnect power and this makes little fluctuations in light bulbs especially that working with out transformer ( resistance bulbs) and we see this case in many voltronic product like expert king or expert max 8k or 11k and so on although I have growatt inverter WPV type and I never tested like this situation in my growatt inverter and we all know that growatt working like voltronic from topology in the end it high frequency inverter and Mppt it’s not coupling with battery. MPPT Is direct contact with dc bus point so any flaw in Mppt can effect the output.

Hi, I found MPPT never dip when power output of inverter above Or below from maximum power output available in solar array but when load of inverter equals to maximum power PV available here Mppt becomes disconnect and returns doing that until you make your load below Or above Mppt power available from solar array.

I tried putting capacitor on pv input like MPP solar said but that is not fixed dips .Actually this effect on output when Mppt disconnect for seconds and I can see that throughout light bulbs… I suspect that algorithm really is bad because using old algorithms to record Maximum power points during daylight day..

really i don't know why mppt is dropping power when battery fully and load stable even i have growatt and we know growatt design not different to much to voltronics and growatt's MPPT stable at all situations why this happens .its because algorithm of mppt is wrong or another issue?

Hi , in Expert king ll or 5048 MKX at bulk stage and when battery reach to be fully output becomes unstable until charger go to float stage. Really it’s confusing to me any one have the same issue.

Hi I installed 50.09 firmware software in my inverter expert king ll Or (5048 mkx) and it works fine in single operation no issues But at parallel operation i see that one Mppt is trun off and return the powering and keep going on .
