one member from this form has the same experience and he has also contacted me . Alibaba is helping this seller to do the scam. Initially I thought its only a problem with the received inverter But they are doing the same with him also. Alibaba will tell you that there is not enfough evidence even if you are giving the evidence . They are just scamming customers with the help of alibaba.

Please help me if any one has experienced the same issue
I have purchased an inverter Called Sunboost VM 4 TWIN from alibaba and facing the following issues
1.The LEB bulbs/Tubes Connected to the inverter will Flicker if solar is present. At night it will work fine but at day time we cant use LED Lights .
Noticed that the flickering issue is more noticeable when changed to 160V range(4 panel series) solar volt and its less noticeable with with solar volt 120 range (3 panel series) . This is the main issue and they are just saying that its normal with their inverter and rejecting the claim.
2. the wifi APP and WIFI Manual they have shared was having many features (Solar of things App) and in reality it will not work with that app and its working with smart life app , then its giving only minimal info. For this they are saying that will give $20 compensation
3. BMS communication is not Proper.
4. RGB LED Ring and Screen is set to turn off in settings but it will be always on even if we are setting it off . For the First few hours the screen off was worked but the RGB is not going off. After 1 day both screen and RGB Ring is not going to off mode
The main issue was the LED Bulb flickering issue . that is making problem in eye and we will also experience issues like head ache if using with this flickering.
Already used different Chinese inverter and I have not noticed any issues like this
The exact model number of the inverter is - SUNBOOST VMIV TWIN 6K .
in the listing its says that - SUNBOOST VMIV TWIN 6K High Efficiency Solar Inverter 4KW 6KW 120A MPPT On-Off Grid Single Output for Solar Energy Systems.
Using the 6KW model , Attached Users Manual . Now added the Users manual since "Crowz" incresed the limit to 10 MB
Unable to attach pdf so added in google drive and shared the link
drive.google.com
I will also include the sample video of bulb when flicking when solar is available (Video 1)and night video when its not flickering(Video2).
Added to youtube as unlisted video so please use the link bellow if needed
Expecting your valuable feedback and suggestions
Thanks
