Are residential electric meters usable for DC, or just AC?
As I get ready to install my power panel to my two arrays, I've bought a standard GE house type electrical meter to keep track of what the arrays are putting out. Now I'm wondering if there is a certain type for DC generation, or if the one that I have will work to monitor what's being produced. I don't have it with me (in storage for now) for information, but it's a traditional analog that's been refurbished. The idea of the incoming power to the charge controllers and inverter is DC and might need a specific meter had not occurred to me until now. I can always use it on the exit of the inverter and see what I've used, but I'd like to see the "gross" input coming into the system without all the variable resistance factors and loss encountered from the equipment after the combiner box and wire run to the MS 150's.
Thanks for educating me on these meters in advance! Lee
