Good info in various threads on this topic. Thanks!
I applied the PREPA Off Grid 83 yesterday via the Installer Toolkit, and noticed there is a PREPA Off Grid 60 in my list as well. I have not looked, but assume this would be 60% / Hz with slightly higher Slow Freq Cutoff since 60% would take about 1.7Hz increase to fully curtail. I can't see the info on the profiles until AFTER I apply and propagate them to my micros (Then hit the info / i button but will probably take a look.
I suppose the next step is to call Tesla and get them to reduce the max frequency. 62.5Hz max should allow my UPS to continue to pass through and hopefully not affect LED lights and pumps too badly? I suppose Tesla will ultimately decide?
Does this frequency change get overwritten once new firmware is pushed to the TEG?
For reference, I have 11.4 kW array with 30x IQ7+ micros and 3x PW2's, installed Oct 2019.
@Jaidmaster can you share the full 60 profile? I'm specifically interested in the Over Frequency Limits, fast/slow, the frequency, and timings. I've applied the 83 profile and it's set to 65.0hz @ 160ms (fast) and 61.8hz @ 1000ms (slow). Since my Powerwall is configured to max out at 62hz the fast will never trigger and slow may be too slow if the PV is kicking out max and the Powerwall is totally full. I'm thinking I may need to update fast to be 61.8hz as well (or update slow to 160ms).
