March 9, 20233 yr @Talino8 Do you have communication between your battery and the inverter?. I cannot afford to damage the inverter again hence i'm asking for advices from people that have done it already and working accordingly or properly
March 9, 20233 yr Author @Phuti I have no communication between the inverter and BMS. I have a homemade battery made of 280k Lifepo4 cells and a JBD BMS. The battery's charging and discharging are managed through the inverter voltages. In case of any issues, the BMS will intervene. It has already intervened several times by disconnecting the battery, and the inverter has not been damaged. The values I have set are 05: USE 26: 55V 27: 55.5V 29: 48V I use these values because they allow me to use most of the battery's charge without putting unnecessary strain on it. P.s. Do you have the link of this seller? I can't find it anywhere
March 9, 20233 yr Author @Silviu TM I tried setting parameter 37 to Hyd, but it doesn't change anything. As the clouds pass, PV begin to disconnect

Here is the link: https://m.alibaba.com/product/1600646977619/hybrid-inverters-2022-new-10.2KW-solar.html?__sceneInfo={"cacheTime"%3A"1800000"%2C"type"%3A"appDetailShare"}&from=Android
March 10, 20233 yr Author Thank you. When it comes to the main issue of the inverter disconnecting the PVs, it seems to happen specifically when there's a voltage drop in the PV array and the available energy is low. This occurrence is rare on consistently cloudy days, but more common on sunny days when clouds pass by. I believe that reprogramming the software could potentially solve this problem, but identifying the manufacturer of the inverter isn't easy. NEXT appears to be the largest company that assembles these inverters. If any of you have encountered this problem and found a solution, please share your experience.
March 22, 20233 yr Seller sent me a new control board. Worked ok for some time but now i'm facing other thing like voltage drop,even if the sky it's clear.it drops till 90v,reduce de curent and than starts again.Before voltage drop inverter starts making a high frequency noise from bottom-middle-left side. I discussed with seller and seems to be pv board issue. This was not a good investment... 😞
March 22, 20233 yr It will be nice if some of you will find a way do solve it in firmware...for me software it's above my knowledge... I'm mechatronics guy, but more to mechanics... I have a control board to use it for testing,with guidance from your side,if will be the case...

March 26, 20233 yr Dne 2023/02/09 v 17:08, Talino8 řekl: Ahoj všichni, Dosud jsem bez problémů používal malý hybridní měnič 3,6 kW. Nedávno jsem se rozhodl rozšířit svůj systém a koupil jsem si 10,2 kW (duální výkon) měnič od Alibaby, který se zdá být neznačkový. Připojil jsem přibližně 6 kW solárních panelů a baterii 105 Ah 16S Lifepo4, kterou jsem si sám postavil. Narážím však na problém, kdy při rapidním nárůstu spotřeby energie ze solárních panelů dojde k odpojení panelů a místo nich se použije energie z baterie. Pokud jsem připojený k síti, odebere to spoustu energie ze sítě. Panely se poté pomalu znovu spojí a začnou opět dodávat energii. Tento problém se projevuje pouze tehdy, když se energie požadovaná z panelů náhle zvýší. Nedochází k tomu, když už spotřebovávám hodně energie z panelů. Problém se stává závažnějším, když jsem mimo síť a baterie je vybitá, protože přerušuje výstup, i když z panelů může být k dispozici 5 kW. Četl jsem zpětnou vazbu od ostatních uživatelů, kteří si zakoupili stejný měnič, a všichni hlásili stejný problém. Dá se to podle vás vyřešit? Je to problém se softwarem, který by mohl být vyřešen aktualizací firmwaru? Přikládám video demonstrující problém. 20230208_151058.mp4
March 26, 20233 yr Good day. Disconnecting the panels - I have the same problem on the same model - victor max 10.2 kw Did you manage to solve the problem? How - in what way - by intervention? You write that the problem is also described by other users of the hybrid - where - on what forum is it possible to read about the problem? Thank you Jan

You write that the problem is also described by other users of the hybrid - where - on what forum is it possible to read about the problem? Thank you Jan I still haven't found a solution. I discovered that it disconnects the PV even on sunny days. Additionally, I realized that another variable to consider seems to be low load. If the output is high, it doesn't seem to occur. At the moment, I have patched the situation in this way: 1)I have created a large battery pack of 15 kWh, so I am more protected from PV disconnection. 2)I added an MPPT to which I connected an additional 2.5 kW of PV, which always supports the charge. Since the first of March, this inverter has produced 600 kWh for me. So, it is true that it has problems, but with the solutions that I have found, it can be used without issues. I am still waiting for someone to find a real solution. Edited March 29, 20233 yr by Talino8

June 29, 20233 yr I have this exact inverter, my version is different (more up to date), the only weird thing I find with it is that for some reason 10 out of my 20 panels are not being considered/connected. I have 9kw in panels and it goes max to 4.5-4.7kw, I assume its a bad connection from the installer but something to keep in mind. (Installer used all PV connections, PV1 and PV2 and im assuming PV2 is wack in the string connection up top or something, if this can only register max 4.5kw-4.7kw of PV then it sucks lol)

The problem with disconnecting MPPT disappears when we load the 230V output with a higher power, e.g. 2000W for about 30 seconds.
October 16, 20232 yr It's not possible to read main firmware from one inverter and copy it to another, without a password and special hardware. It is however possible to do this for display firmware, as others have demonstrated on this forum.

It is however possible to do this for display firmware, as others have demonstrated on this forum. Unfortunately, Daxtromn no longer sells a separate control board. I wonder which signal/voltage level at the input of the control board disconnects the MPPT charging, I measured the pins during operation and the voltage changes on two of them as the power of the MPPT regulator increases. The load on the converter causes the MPPT controller to work continuously, I have a Jtag cable and several programmers... The inverter and its basic function, the MPPT charger, does not work properly.
October 17, 20232 yr You can't mix 8 and 10 kW firmwares anyway, except perhaps for testing. These are not Axperts, so commonly available firmware won't work. Although you can't get a replacement control board, perhaps you can get a firmware update file from Daxtromn. The way that Axperts control the high voltage solar chargers is via a separate connector, not the 48-pin connector on the main board. But these may well be different.
January 3, 20242 yr Helló mindenki. Van egy Daxtromn 8,2 kw-os inverter, ami ugyanazt produkálja PV oldalon, mint itt sokan 🫣(355v 16A sztring) az inverter nem akar semmit.....jelzi, hogy van napelem, beköti, majd szétkapcsol ! Itt a videó a meghibásodásról.... Sokan írtak a vezérlőpanel cseréjéről! A vezérlőpanel cseréje megoldja a problémát???? Vagy esetleg firmware frissítés kell hozzá??? Előre is köszönöm a válaszokat 🫡(az inverter többi része jól működik)

October 31, 20241 yr Did anyone have a link to that exact model , mines bus soft start is failing despite replacing all components
