As Support says, don't do it. I have Sense + 2 PWs, and it's just another pile of disappointment on the Sense fire.
If you clamp your Solar and PWs together, you loose all ability to track your solar production via Sense. It's also a question of how to clamp them together as PWs can be spread over 2 breakers independent of your solar breakers. It's better to have a custom install with a combiner box (for PWs + Solar breakers) just to cater to Sense.
Sense refuses to put out a 6-CT device that would easily solve this. One solution I saw was to buy another Sense monitor just to monitor PWs. It may aggregate the date from multiple Sense devices, but check the forums for caveats.
If you don't clamp your Solar and PWs together, Sense looses ability to accurately track consumption AND will randomly auto-calibrate in a way to think your PWs is solar, and your Solar as consumption. The only way to fix it at that point is to delete your Sense account in order to factory-reset it, losing all historical data.
