Just had an 8.16KW and 3 Powerwall installation and did a nice long system test yesterday. Since I don't have PTO, I disconnected the main service breaker first which kicked me into back up mode. I then engaged the inverter and the panels. Most of the power generated went to charge the batteries which started out about 18%.

Worried about how the system might mess with Insteon communications, I did a query on everything (about 200 devices). This normally takes about 2 minutes. But off the grid, it zipped by in 20 seconds or so. This is repeatable. Turning solar off (but still with powerwalls connected) and the main service breaker back on, times go back to the typical 2 minutes.

 

I'm assuming that this means there are lots of retries. My Insteon network is mostly reliable(99.9%) but I assume it's just that the retries hide failures. Likely that powerline is very unreliable and that wireless it what's mostly succeeding with the non dual mode devices receiving their signals from closer dual mode devices that acted as wireless relays. 

 

So what could be going on here? Unclean power from PG&E? Interference from a neighbor?

 

 

Set your ISY log to level 3 and do the query both on and off grid. Save each log to a file.

Compare the two files.  20 seconds for 200 devices is unbelievably efficient.

Do have any battery operated RF only devices?    My log shows 10 -20 seconds spent just for 1 Motion sensor ( which it cannot reach since it is sleeping).

I agree with ELA. That's extremely fast...Waaaaay to fast for it to be doing anything
