Was looking at some of the hardware available but it shows up to 12 monitoring connections? I have 40 breakers and I want them each individually monitored on a dashboard. Can this tech do that?
Welcome, Adam, to the OEM forum.
A one word answer: Yes.
You will need an emonPi2 with a Raspberry Pi 4B to provide the first 6 channels, then 3 × emonTx4 (or emonTx V4 - the same thing), with expansion boards to provide 3 × 12 more channels. You’ll have two spare channels.
You will also need a 3-phase emonVs to provide the voltage measurement of the two legs of your split-phase supply and power for the emonPi2 and at least some of the emonTx’s, hopefully all, but I will need to check the total power requirements, plus of course you will need 40 c.t’s of varying ratings and miscellaneous leads and connectors. I’m anticipating all items will be located close by your load centre, and you’ll be using a direct USB connection between the emonTx’s and the emonPi.
Possibly the most important question at this stage is, is there room for 40 c.t’s in your load centre? The ones we stock in The Shop are split-core, which take up more space than the equivalent solid-core. If you’re able to disconnect wires from the breakers to install the smaller solid-core c.t’s, this might well be an important point to consider. The appropriate c.t’s are widely available.
