FLEXY Flexi 2 Ton Split Air Conditioner

I bought a 2-ton split air conditioner, but I haven't used it because it's difficult to run on solar power, so I want to exchange it for a 1-ton unit. I purchased it for 2000 riyals a month ago, and it still has a new warranty from the well-known company FLEXY. I'm asking for 1500 riyals, and may God bless you with the remaining 500 riyals
