question

good morning, I have a doubt.

I have seen that the victronenergy pwm bluesolar pro and bluesolar duo controllers are IDENTICAL to the pwm Epever Landstar B and Ep series duo controllers.

Even the "solar station monitor" PC control software is exactly the same.

The victronenergy remote monitor is also identical to the Mt50 Epever.

As well as all settings and manuals for these products are identical.

I would like to know if the product is from victronenergy and has been copied with or without permission from Epever, or vice versa.

Or there is an external manufacturer who supplies the products to victronenergy and Epever, and they place their own brand.

Thanks
