Question Quietly posting Firmware Update - WHY?

Once again a NEW firmware EG4_FAAB-2727 was posted (for Flexboss / 12kPV / 18kPV).

• WHY does this forum exist?
• Why do we have to randomly check?
• Why is there very little detail to understand if this addresses previous issues?
• Who should consider skipping this release?

Firmware is important! Without it these inverters would just be noisy wall heaters.

I implore EG4 to treat software as its own product. It is our OS.

Please don't bother if you are just going to return to this post and say Whoops AGAIN.

      I'm hoping there is impactful information beyond the bulleted list that can be offered.

2026-03-29      <=== Its only been a week

• Based on FAAB-2626/2525.
• Match LCD V25.
• 1. Improved. New England Grid Profile — added regional grid profile support for New England configurations, with Voltage-Active mode disabled by default.
• 2. Improved. Added RS485 BUS communication support on the Meter485 port for PPL Electric installations.
• 3. Improved. LUMA Grid Profile: Voltage-Active Power mode enabled by default.
• 4. Improved. HECO Grid Profile: Frequency-Active Power mode enabled by default; under-excited reactive power set as default.
• 5. Improved. Optimized charging power limitations when PV power is unbalanced across inverters in a parallel system.
• 6. Improved. LCD phase setting labels updated from R/S/T to A/B, B/C, C/A （LCD V25）.
• 7. Improved. Update fan logic to start fans at a lower temperature to optimize heat dissipation.
• 8. Bug Fixes. Fixed repeated switching between on-grid and off-grid modes on the secondary inverter triggered by off-grid cut-off voltage in parallel shared-battery and lead-acid battery mode.
• 9. Bug Fixes. Reduced probability of repeated state switching between PVBatGridOn and PVChgGridOn.
• 10. Bug Fixes. Fixed the inability to exit on-grid AC couple charging state and switch to battery discharge when load exceeds AC couple power in a parallel system.
