This is a topic of high interest to me right now. Some 5kw surplus SE inverters have come on the market recently for <$400. I BADLY need to learn how to use them without the expensive optimizers. Any suggestions? I have a test inverter which I have not been able to get to work. The next test will be to put one or two optimizers in the string.
So it’s my understanding that modern solaredge inverters require optimizers. However, they do allow two panels per optimizer if you get one of the larger optimizers, so that might save some cost. There was also someone who posted recently about tesla calling for a SolarEdge string optimizer, model number SO5000. The data sheet for this device was posted here:
The latest systems components y'all getting from Tesla these days?
I have never seen or heard of this device before and I spent a bit of time googling it and I couldn’t even find any references to it anywhere. But it appears that it is a single optimizer that will handle a whole string of panels. If you can figure out where to get such a thing then it might be an option for you as well.
