I'd like to start with a couple DIY experiences into solar panels.
My question is regarding the inverter wattage.
I mean, if I pretend to make a cheap solar panel with a maximum possible wattage of 150w, connected to a 12v 20Ah battery. Should I buy a specific inverter for medium-small size projects?? Or could I buy, let's just say, a 1000w one? because gradually I'd like to increase the size of my projects in the future (and save some money)
Thanks in advance
