Hello, Amir, I have never ever seen a PurePower and I'm far from being a electric engineer, but I'm convinced this "reduce dynamics" thing is at least partially related to the fact the power conditioning device isn't sized to the...

With all the previous talks about batteries, any one tried (or have any idea about) using large/industrial supercapacitors instead, maybe followed by a isolation transformer? I mean the whole "kill dynamics" thing isn't supposedly to happen sinc...
