Ah, perpetual energy without solar panels or a generator!
Readers of this website normally can’t contact me, because there isn’t a “Comments” function, nor is there an “Email” button. But hey, this is the Internet Age, and it shouldn’t be too difficult to contact me if one really wants to. Then of course, it is more than likely I will ignore you. However, in this case, I recently received an interesting inquiry worth discussing.
I read your posts on solar and batteries and have a question. Why can’t I just connect an inverter to my trailer’s battery and then power a battery charger with the inverter. Seems the battery would always be 100% charged.
Not only is the answer, “No,” but trying to do this will cause a battery to go dead very quickly. There are two ways to explain this. The first is by using some simple math, and the second is to experiment under real-world conditions. I’ll do both. Before we start, we need to define a couple terms.
