Skybox with Enphase Iq7+micro inverters

Post by wtfg »

Anybody here AC coupled to Skybox with Iq7+ micro inverters ?
Probably not in California
I would like to know what you have your Grid Profile set on the Micro inverters ?
And what setting are you using on the Skybox IEEE 1547 2003 or Cal rule 21 LS & T

I'm using Emphase M215s with the Skybox default profile, IEEE 1547 2003. Also the grid profile on these inverters isn't settable. I have no idea what it is.

Edit - did a Google search and apparently the M215's grid profile is settable. But I haven't touched it, no need in Ohio.

My RE system: 7.9 kW self installed Enphase system NEM 2.0 PTO 9*2021. Skybox, and heat pump/AC system. The Skybox is powered by a 42 kWh pack of LFP batteries and 2kW panels. It will be used in self consumption mode for load shifting and backup.

Sorry to see you are still having issues. I thought I answered that question earlier. I did not change anything on my IQ7
Grid Profile. I assume it is the default 1741SA following CA Rule 21. On the Skybox, I was using Self Consumption until November when I changed to Backup because there was not enough solar to charge my batteries every day. That mode includes TOU so my loads are only maintained by the Skybox during peak times. At off peak the Skybox charges the batteries from the grid.
I actually have not tested my system in a grid down situation but I see AC coupling passing the power from the IQ7s through the Skybox to the grid.
Remind me what the issue is that you are having to save me searching through the threads?
