Re: [RE-wrenches] Galvanized vs. Aluminum WAS: 14 inch aluminum standoffs?

Hi Andrew, Would anodizing the aluminum offer any benefit to you ? One of the non-traditional solar mount suppliers offered just such a galvanized product and even sent out samples of their product. I put my sample outside to see what kind of performance it did offer. Probably something on

I want to understand the issue if you don't mind. Are you saying that an MPPT charge controller has no voltage limits? I would have presumed a CC would know that there is no batteries attached. From your email, you want a device that will measure the CC output voltage, and shut it down if it

Chris Yes some charge controllers regulate pretty slow. So if the battery goes away on them they can skyrocket in voltage on there battery side before they can catch themselves. This may only be for 2-3 seconds or so but that is all it takes to send an inverter up in smoke. This is also the
