SOC thresholds (lithium mode)
Battery Cut-off SOC —% 0x03F2
Battery Low to Charge SOC —% 0x03F3
Battery Back to Discharge SOC —% 0x03F4
In lithium mode the SOC thresholds are used. But note: Voltronic OEM firmware treats "Back to Discharge" as fully charged for lithium packs regardless of the SOC you set here — that's why the inverter stays on grid above the resume threshold until the pack hits float. Switching Battery Type to User defined makes the voltage-mode threshold authoritative instead (at the cost of BMS integration).
Output
Output Voltage — 0x03FC
Output Frequency — 0x03FD
Output Mode — 0x03FE
Grid input
AC Input Range — 0x0406
Overload Bypass — 0x0407
Feed Power to Grid — 0x0408
Source priority
Output Source Priority — 0x0410
Charge Source Priority — 0x0411
Output Source Priority = Solar-Battery-Utility (SBU) is the one the firmware's "fully charged" lithium latch depends on — in SBU the inverter uses battery only until it drops below cut-off, then latches to grid until float. Setting it to Solar First (a.k.a. SUB) bypasses the latch: grid handles load when solar falls short, without the cut-off lockout. "Utility First" is the factory default — grid always runs the load. Changes take effect immediately.
