I wish some of the HN crowd can take a crack at building an affordable hybrid inverter with good software. Fronius/Ecoflow/Anker solutions are too damn expensive.

Currently the cheap hybrid inverter on the market usually comes with crappy monitoring software.

What would it take for a solar cell to directly output alternating current?

Alternating sun and moon exposure.

So Earth spinning very fast

It might be easier to spin the panel.

Micro inverters are a thing: https://enphase.com/en-au/installers/microinverters

They work for individual solar panels.

Yes. These output AC per-panel. Connect'em in parallel. Presumably the amperage is related to the incident light intensity.

Entertaining idea, the panel with a 50Hz fan blade in front of it, but in practice it's much better to not compromise the beautiful simplicity of the photodiode and just stick an inverter on the back.

Happy to pick up the gauntlet. EE here with strong skills in ucontrollers, comms, and software stack, seeking to partner with other EEs to take on the power electronics part. Anyone interested, please LMK.

ugh tell me about it. I have a Delta inverter.. the interface is rou out of the late 90's... its so bad it passes the password through the url in plain text.

am actively looking to replace it
