Make a purchase of a solar panel, it arrived super fast in perfect conditions, I made the purchase by WhatsApp of the store, I just think it would be better, after the seller makes contact with us, it will always be that he would take care of us, since I tried to buy more things but the electronic system of WhatsApp ends the contact when one of the two sides takes time to respond, then I bought some other things that I was looking for at MercadoLivre, but I'm already planning to buy three more cards and an inverter on grid with you , because I already researched and in my solar house is where it has the best price.
