Split phase whole panel energy monitoring

Energy

So, I’m cursed with the awful, antiquated, difficult to work with US split phase system with it’s terrible service panels. Anyone know of any off the shelf energy monitoring kits that support monitoring an entire fully loaded service panel for US split phase? I’ve found a few 30+ channel units from the usual Chinese sources, but they’re not designed for split phase US power. Oh, and when I’m talking about monitoring an entire panel, I mean monitoring the two main phases, along with ALL branch circuits, on a single unit. A fully loaded 200A 40 space panel could be more than 40 branch circuits depending on the circuit layout.

I figure if someone sells one, it’s likely going to be cheaper and save me a ton of time over designing my own. I’ll design my own if I have to though, particularly if there’s any community interest in such. Maybe a 24 channel version for 125A 20 space panels and a 48 channel version for 200A 30 and 40 space panels?

You can combine multiple breakers into one channel so that the whole panel fits into the currently available16+2 channels products in the market. Not ideal but a working solution.

I just purchased a bunch of 2 clamp units from AliExpress and mounted them on a rail. They already come with a rail mount. Each unit will handle 2 circuits (80A) For double breakers I just use a single clamp and create a helper in HA that doubles the Energy/Power. I printed a clip that holds a couple of wago clips to power the whole group. A 12" rail holds 5 units (10 circuits)
You would need a larger Amp unit for your mains power.
