The inverter got to it's destination yesterday. 5-10 days to repair, then return shipping.
In the meantime, the cheapo inverter is doing it's job. The whole system has been running since the 17th. With the new battery, the voltage never drops below 12.6VDC overnight, which for a lead acid battery is considered still fully charged, and peaks up by noon, sun or cloudy. The frozen water bottles I put in are still rock hard frozen on the bottom of the fridge, the soda bottles one rack up are not frozen, but when you crack the seal, they crystallize. Perfect temp for soda.

..if not, just drop it by the shop and that SGI feller that claims to be a genu..geeni..genw...really smart feller about all things electronic could take a look at it for ya.
Then he declares it irreparable.
Then he fixes it.
Then I have the first component for my copy build of your system.
So... He's Scotty?

I might have a clue as to why the first inverter failed. The fan never turned on. I just assumed it never got to the fan trigger point of 65*C, it was relatively cool to the touch. The fan turns on with the new one. I'm thinking the fan was broked and the unit burned up internally, even tho it didn't feel warm.
...and so down goes the conversion efficiency too. Be interesting to see by how much..

Probably going down a bit, but the battery recovers so quickly in daylight that it's negligible. Decided not to even keep track at this point. It's working far better than I had ever hoped, and that's good enough for me.
No doubt now that the 1st unit failed because of a non-working fan and overheated. This one turns on often, and in the late afternoon/evening the temp in the garage is hot enough to make the fans turn on with no load. The 1st unit fans never turned on.

So, one more experiment.
Can a solar panel make power from a full moon?
Yes. My panel generates 1.2VDC (loaded) from just the moon. It's not enough to trigger the charge circuits, but there is some power available.
And BTW, the solar system has been powering the fridge/freezer non-stop with no interruptions since mid-July. I've had bottles of water in the bottom that are frozen solid.

Don't know, haven't really done much looking into large scale batteries. If you're interested, this guy does a lot with Tesla products and builds his own Powerwalls.

Since Solar City is a subsidiary of Tesla, it's most likely the same thing.
