Electronics is simple math. I don't need to explain that to you. Are you telling me that this guy is somehow able to defy the law of physics? A single photovoltaic cell produces a measured amount of current under differing Sun exposure. An array is just a bunch of cells soldered together. They don't respond to outside stimulus from a controller, other than to connect or disconnect the cells from the circuit or a variety of circuits. They don't accept vitamins or pep-pills. This sounds a little like "Snake-oil" to me....
Although they do respond to cleaning now & then....
I'm just not interested in controllers
. Too many years with toooooo many very expensive gadgets (remember me....I'm the gadget guy). When I put an array on my house, it will go right into the grid. No controller needed there either, just a nice expensive inverter......
