I wonder if there is a thread on this forum that shows all the different firmware updates on the 18kpv and what they help in doing? going to eg4 web site don't show them all. I've seen here through some of these pages discussion but not a complete organized list, or missed it.
FAAB-1616
2023-10-20
Changes log (Same as fAAB-1616)based on FAAB-1312;
1. Optimization on frequency shifting for AC couple function has been done .
2. Optimization on Zero export function : Stop frequently switching between PV charge +Grid on and PV+Battery grid on modes .
3. 3phase (208Vac/120Vac)parallel solution has been supported : 2 *208V 3phase parallel and 3 *208V 3phase parallel are supported .
4. Optimization on EPS transfer time has been done .
5. RSD active signal to BMS has been added : Battery needs to support the respond to RSD demand too .
6. The setting range of Generator rated power has been changed to 255kW max and 1kW min .
7. Logics optimization : Once "Fast zero export " function is enabled, " Grid sell back " function won't take effect .
8. Refined parameter adjustments for Battery control: OnGrid cut off VOLT form(40-52V)to(40-56V); AC Charge Start Volt from(38.5V-52V)to(40-57V); AC Charge End Volt from(48V-59V)to(42-59V); Gen Charge Start Volt from(40V-59V)to(40-57V);Gen Charge End Volt from(40V-59V)to(42-59V),ACCouple Start Volt from(start-59V)to(42-59V).
9. New Feature for LCD display: "Connect in xxxs " for the waiting time to on-grid mode will be showed at the top line of the home page.
10. Logics optimization on Generator dry contact control : Warming up the generator for 2 minutes before entering charge mode , and cooling down the generator for 2 minutes before cutting it off.
11. Optimization on voltage drop of EPS output while connecting or disconecting with heavy load has been done.
12. Logics adjustment : When forced discharge function is enabled , AC coupling power will prioritize to export to grid instead of going to AC charge mode.
13. Logics adjustment : When PV energy is weak ,to prevent switching PV grid on mode frequently with high frequency relay clicking noise , the time delay to enter another check changes to 2 seconds.
14. New Feature: System charge end SOC:0-255% ,VOLT :40-59V.
FAAB-1312
2023-08-16
Changes log (Same as fAAB-1312)based on FAAB-1010;
1. Optimized surge power and addressed voltage drop concerns when operating in EPS mode.
2. "PV sell to grid" function is supported ; Note that it's not yet available for parallel systems.
3. Refined parameter adjustments for LUMA Grid regulation.
4. With firmware version FAAB-1010, enabling the "run without grid" function won't activate generator dry contact logic.
5. Resolved EPS overload triggers from both total EPS voltage and split-phase voltage.
6. Improved control to prevent " BUS voltage High " issue when operating in AC couple mode.
7. Enabled RSD control synchronization in parallel systems.
8. Implemented "strict zero export "; When PV and battery energy suffice for loads, the inverter won't exchange energy with the utility grid.
9. Modified AC coupling input recognition, treating it as PV input with equivalent priority as integrated PV power.
10. In previous firmware
FAAB-1010
and with fast zero export active, the inverter won't switch to PV charge mode when battery energy is low.
11. Improved surge capacity : For power levels between Pn and 1.16Pn, 10 minutes; and between 1.16Pn and 1.3*Pn, 5 minutes.
12.Default settings for Lead Acid mode include a charge voltage of 55V and charge/discharge current limitation of 0.5C..
13. Enhanced generator quick start functionality.
FAAB-1010
2023-06-30
Changes log (Same as fAAB-1010/ eAAB-1010/EAAB-1010)based on FAAB-0D0E.
1. Enlarged the grid sell back power limitation ,if power limitation is high than 200% , then real limitation will be 1000% max.
2. Peak-shaving logic optimization.
3. Fortress battery protocol optimization :working in leadacid mode where is communication failure issue.
4. AC Charge according to SOC or VOlT could be supported in this firmware version .
5. Octopus charge function is supported.
6. To avoid relays clicking on and off frequently due to grid fluctuation, a return value has been added in this firmware version .
7. Hina battery protocol is supported in this firmware version.
8. Grid regulation changes :Hawaii changed to HECO , and added KIUC grid regulation.
9. Battery capacity could be showed in the LCD display .
10. Optimization on AC coupling function : AC charge and battery discharge will be seamless switching way .
11. Fans control logic optimization to reduce fans noise

2023-05-12
Changes log (Same as fAAB-0D0E/ eAAB-0D0E/EAAB-0D0E)based on FAAB-0C0D
1. Fixed the logic issue when PV energy is low , the inverter would fail to switch work mode from PV charge to battery discharge
2. Optimized charge logic of AC coupling input and maximize the use of AC coupling charge
3.Optimized the logic of charge limit in AC charge mode.
