Cost effective cover for outdoor solar inverter

[Sugar]

hi Guys,
Recently I have got solar installed in one of my investment property.
It is sungrow 10.56kw. This is my solar inverter. 

The inverter is outside the house. The house is double storey house.
I would like to put something to cover the inverter from rain and may be direct sunlight as well.

Are there any ways to make and install cover that are not very expensive.

While googling I found something like this : https://covermyinverter.com.au/
this is little expensive for me

I also found this in bunnings. https://www.bunnings.com.au/altamonte-1200-x-700mm-siena-tinted-canopy-with-plastic-bracket_p1010476

And I also saw someone using above product :

This is little cheaper, but when the rain comes from side, it may not block rain at all.

What could be most cost effective way to do it.

Thanks
