Solar-powered battery running my system
We're getting solar for our house and will be generating a pile of free electricity. We'll also have battery backup. I now have to choose what systems to put on the backup power panel for outages.
BUT
This also gives me the opportunity to make my full surround listening rig one of those. I've read a lot of people talking about the horrors of "dirty" power from the grid. This will be the cleanest, sun-produced, electric manna from heaven stored in a Tesla Powerwall and available every day. Is this really the amazing upgrade the power fans claim? The cost to me is pretty minimal to have it run my system.
The quality of power output from the Powerwall is governed by the inverter. It may not be that clean. The Enphase IQ7+ microinverters on my PV array output AC at no greater than 5% THD. There’s also the recommendations per IEEE 519 on THD in power delivery.
I managed to find a post from someone who took images of an oscilloscope showing the waveforms for mains and Powerwall power. |
