I'm not sure it will come to anything but I saw an online petition to have NEC remove the module level shutdown and return to the 2014 rule with array level shut down. on the off chance its legit and could make things better there is a link. https://www.fixmlsd.com/danrjones wrote: ↑Thu Mar 25, 2021 12:14 pm
Yes, each module came with a rapid shutdown module that goes under the panel and produces about 1v. The SMA inverter activates them all. Seems to work fine, I wish I did not need it, so that I could have had a plug on the inverter for any power outages... but it was required.
Side note, I saw an article this AM that all the power companies are pushing hard for huge changes to NEM in CA. They want drastic reductions in the NEM credit as well as monthly fees ranging from $50 to $90 for the honor of being on the grid.
I do agree that we solar folks need to pay some amount as upkeep for the grid, since we are using it. I don't know what the right amount actually should be. Currently SCE charges me about $11 a month minimum for that, even if I produce more power than use.
Personally I think they need me more than I need them. I would need a battery install but with that, I make plenty of power to be off grid. I think technically I can't legally BE off grid, but I'm not paying $90 for essentially a connection fee. What do they do if you refuse to pay your power bill? Disconnect you? Perfect. So we shall see where that goes, but NUTS to that.
On the other aspect about going off-grid or what I recently learned is called "grid-fall-back" it seems like the way to go. Its a world-wide issue, Down-Under the grid stability is an issue with the quantity of solar they have, they sometimes need to install synchronous condensers to correct issues with grid inertia. In Ohio they are converting old coal/steam generators into synchronous condensers for similar reasons.
on the net-metering If you look as CAISO they have to curtail so much solar in the middle of the day its insane, so I see their perspective. why should they pay people whatever per kilowatt hour at noon, when they are curtailing 10's of gigawatts of their own solar. its an information problem, because an individual with a 'grid-fall-back' solar+battery can choose to run loads midday for themselves, pay no extra grid service fee and still get the privilege of unlimited power when the battery is dead for only the $7/mo cost of the meter.
