No ofc it only happens when on inverter mode(sun and no sun), so no grid , no regulators. just pure chinese juice all ratings seem fine the only thing i think about is that there is a problem in the output waveform , the only access to an osciloscope is in my college and they r not planning to lend me one 🥲

1- The only thing similar to this that i noticed is when i put the inverter mode on UPS it repeatedly draws about 1Amps AC on and off and on the battery end at the same time it cycles between drawing 1.5A at 25v which is the normal no-load draw to 0.4A and then again to 1.5 and so on.... I changed it back to APL and it stopped doing those weird draw patterns. 2- A question for fellow 4kw VM-III owners : Do you guys notice flickering on neon or incandescent lamps because some times the flickering becomes noticeable to an annoying level ! and by the way i tried with no-load , high-load and it's the same.

Hello i have a question that have been on my mind for a while and i couldn't find much abt it I have seen some people that argue abt the effect of resistive loads or induction cooktops that have a Dimming capabilities some say its not recommended for the inverter and some say it'll affect the sinewave purity and affect other electrical equipment that are running off the inverter has anyone done some tests to see how different load types affect the output using an oscilloscope ?? " images attached are from a video i found that tested the output when using a common dimmer circuit on a resistive load this is the outcome : RIPPLES "

no it only goes down which is annoying if u skipped the setting u want you'll have to to go over again from the start🫠

it was already on SNU but the output priority was SUB i changed it to USB and it solved the problem but the thing is why didn't they add an only utility charging option

Hello can someone help me i got a new 4kw vm iii and its connected to the battery with a bms com cable the thing is today at 6pm the grid came back and the battery was at 20% but it didn't switch to charging from the grid , it stayed charging slowly from solar at abt 8 amps dc which is pretty low ofc is there a way to make it like smarter ! why is it charging at this low solar current instead of charging from the grid at the set maximum grid charging current 30A ?? --- it's set at SUB does changing it to USB solve the problem ??? ---
