I have seen at least a couple of posts now about people using the 50A CT sensors to monitor the specific solar generation by simply connecting it (per the instructions) to the circuit breaker going to the inverter (or inverters as it may be). These folks (myself included) are realizing, however, that after the sun goes down they are still getting readings on this sensor feed from other items that may be on that circuit AS WELL.
For example, in my case I have a 50A CT sensor on a single leg of my double-pole breaker which feeds a sub-panel in the garage, and within THAT lies the breaker to the solar inverter (as the panels are on top of the garage). From there I then just set the multiplier accordingly and all is good. Here’s the problem though, there are other items in the garage that are connected to that sub-panel, not just the breaker for the inverter, so you end up getting readings from all sorts of craziness throughout the night, that depending on what all you have in that sub-panel, skew the bejesus out of that Solar Generation reading.
Now, if you could tell the system, or at least that specific sensor to stop monitoring THAT item at sundown and start again only at sun-up, while it may not totally resolve the issue (as you are still going to run these things inevitably during the day), it would make it worlds more accurate.
Is this correct, or am I doing something wrong / not visualizing what is happening accurately?
Thank you!
