So you're saying that if I were to put a PV module out in the sun and not hook it up to anything at all, it wouldn't be a source of voltage?
And that the many standalone PV pumping stations installed on ranches don't work because they don't use batteries?
And that SMA inverters provide AC power without batteries. (and, presumably, could be scaled up, paralleled or installed in multiples)
But there's some fundamental law of physics preventing them all from working?
Well, I wasn't going to dive that deep into this, but yes, of course, you can use the DC from solar modules as long as the consumption of the load is free to vary with the insolation on the array, i.e. the brighter the sunlight, the harder the pump (or whatever) works. That's very different from supplying power on demand. Current source vs. voltage source.
The SMA inverters you mention are no longer in production (I don't know why), but no, you cannot parallel their single outlet outputs that work (worked?) without the grid. Even the largest ones could only supply about 1200W to a single outlet.
Sounds to me -- after pushing aside all the bovine biosolids -- that what you're really trying to say is that the popular inverters require some 60-Hz energy from an external source for excitation & synchronization and refuse to turn on without it. That's a design limitation of those inverters, not a fundamental law of PV physics.
It's not just the popular GT inverters, it's all of them. Don't you think that if it were possible for a PV inverter without batteries to work with a transfer switch and go on supplying power on demand to a dwelling in the absence of the grid, someone would be doing it? The problem is that PV modules are current sources in the linear range of their operation and therefore the inverters for which they are the only power source are as well. The demand curve and the supply curve will never match precisely, so in order to run off grid it is necessary to have a battery bank to provide a buffer between supply and demand. When an inverter is connected to the grid, the grid is the buffer. This is indeed a fundamental of PV physics.
If you think you can get around this, well, do it. You'll be very wealthy.
I don't recall mentioning the government's role in PV installations. It really isn't necessary to provide rebuttals to claims I didn't make.
It was the absurd assertion that the reason PV systems in Florida shut off when the grid goes down is that that PV owners there were "not allowed" to use their PV systems in the absence of the grid that started this line of discourse. I wasn't necessarily replying specifically to you.
