Thanks; I'm working on products in this area and not especially satisfied by the parts available. Especially as Analog seems to be abandoning their micro-MPPT IC product line. My email is jacob at jbaylessconsulting dot ca.

One of the common issues with solar micro-MPPT is EMI emissions. Have you tested for compliance with emitted radio-frequency noise standards?

Yes and no. If you run the inverters or network at 100Khz up to 1 Mhz you get much different EMI than if you run them at 1 Khz. The inductor and ADC also play a role. We will know this only after we mass produce the chip, my test chips and prototypes (with RP2040 and Padauk PMS150) have similar but not the same EMI emissions.

- We could package the chip, for example wrap it entirely with the metal inductor. That works as a faraday cage and block the emissions. But will this raise the price?

- You put the chip between the solar cell and the (flat) wires. That works as a faraday cage and block the emissions. Will the solar panel maker do this?

- You could have solar cells without the panel, think fo a CD size solar cell encased in plastic just as a CD is a metal foil encased in plastic. Now you can wrap the chip and block the emissions. You can hang the cell from the wires (in a tree or on the distribution wire like christmas lights)
