The “Mains” values are two colums with to numbers always pretty much the same (3000 W 3600W), (2100W 1800W), (5000W 5400W), etc.
Are those the values of my 1st 200A panel the the 2nd 200A panel in real time ?
If so, unless I dont understand something, why are they always really close to each other ? And no, the load is not as perfectly balanced all day between the two panel during the whole day as per appliances, heat demand, etc.
I’m I missing something or not understanding something ?
From what I remember from the beta testing of the split 400A service, the Signals section doesn’t break out the contributions from each pair of CTs (each box or however your busses are split). You only see the combined total.
The two columns are the two “legs” of the split-phase electricity in your house (I added the red L’s)
So I probably don’t understand how each panel receives his required electricity. I guess the main 400 pushes about evenly the highest required watts to both panels at the same time ?
So if one of the two 200AMPS requires 25 000W, and the other one 100W, it will “push” 25 000W to the first panel and maybe 24 500W to the 2nd 200AMPS panel ?
@freddyboy1 , you have an pretty good intuitive feel for how electricity works. Voltage is like pressure, so the grid keeps a steady 240V (120V on each leg) “pressure” going into your house and the same “pressure” splits between the two different breaker boxes. The different hot legs are different colors in your house, typically black and red. There’s also a neutral wire for the current to flow back through, but I have omitted from this picture I borrowed from the web. The Sense sensors are the little white bars crossing the feeds.
The voltage pressure stays the same, but the current varies depending on the load. And the power is essentially the product of the constant voltage and the current. The numbers you are seeing are the voltage and the sum of the power for the two L0’s and the two L1’s. There’s only one voltage for each LX because they are connected. And usually, the power usage between the legs are similar, though not exactly the same because of the way breaker boxes are designed to balance the load between both legs.
