- 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.

I’m sure a sigi infant effort was made on the improvements.
Could you find out more specifics on #7 fan logic? on the 12kpv it has been observed to go all on around 6kw.
which temp indicator is this now watching to turn on/off?
Are fans only capable of single full-speed?
It would be kind to not make us run dozens of tests to revers-engineer the fan algorithm.
