EG4 18kPV Q+A general thread

Mine says "no limitation"....and I didn't change it to that so I'm assuming that's default?
the max ac input is the max power that the inverter will pull from the grid without tripping the grid input breaker. For example if the grid input breaker is 125A*80%=100A*240=24kw.
if you use 200A leave it as default no limitation or 6553.5.

So what would it be set to for a grid input breaker of 40 Amps. 6553.5/200A = 32.7675 X 40 = 1310.7? thanks
 
The thing that was throwing me off was "Max. AC Input Power(KW)" Kilowatt. My default setting of 900. So 900 should be 900,000 watts.

Another update:

Lots of goods for us AC coupled folks. Not sure what they mean, but I've been running it all day and so far so good.

FAAB-1A1A​

2024-04-22​

  • Same as fAAB-1A1A, changes based on the FAAB-1919.
  • 1.Add 2 minutes of Warmup to the generator microgrid mode.
  • 2. Add split phase voltage overvoltage and undervoltage protection for US models.
  • 3. Improvement, keep off-grid state when countdown to connect to on-grid mode.At the end of the countdown, it will quickly switch from off grid to on-grid mode.
  • 4. Improve load calculation in three-phase parallel and on-grid mode.
  • 5. Fix the issue of using Grid AC to charge even when SOC/Volt reaches Stop AC Charge SOC/Volt when AC Couple and AC Charge are enabled.
  • 6. Optimize AC Couple power display.
  • 7. Fix the issue of the original AC Couple power not being able to reset to zero when the AC Couple is disconnected from the grid and there is no grid power.
  • 8. Update PR-LUMA grid regulations parameters.
  • 9. Update register information for "Permit Service".
I am glad to see continued updates. As a OFF-GRID user, we tried 1A1A yesterday. Comparing to other updates done on this 18kpv, FAAB-1717 was switched back too, by the end of the day.

"In relation to starting a Quincy QT-5 compressor with updates,"

FAAB-OEOE showed biggest change from factory settings. Some random slight flicker would happen once in a while but took the longest amount of time before time out.

FAAB-1717 update showed to be increase in speed turning compressor motor over, just not long enough before time out. Stable, no flicker, no other issues.

FAAB-1A1A loaded in yesterday, Noticed a slight increase of speed turning over comp motor for a longer duration before time out than 1717. This is probably the most powerful update yet but it showed to make house lights flicker at random, through out the house all pulsating at the same time. LED and incandescent bulbs all together at the same pace. Flip off some circuits/ then back on it would stop but start again, even after reset. Switched back to FAAB-1717, problem gone. If not for the random pulsating I would have kept this update, but every thing must get along.
There will be more tests here as some thing stronger comes about. I think there getting close to an update for these old school industrial compressors, just not quite there yet.
