All Outback devices provide Status packets in response to a Status command:
Port (00: No Hub)
| Command (04: Status)
| | Address (01: Status Page 01)
| | | Value (Unused)
| | | | Checksum
| | |………| |………| |………|
TX: 100 02 00 01 00 00 00 03 (Command)
RX: 102 11 22 33 44 55 66 77 88 99 AA BB CC DD EE FF (Response)
| |………………………………………………………………………………………………| |………|
| | Checksum
| Status page
Device Type
Status responses are always 13 bytes long, but unlike other commands the first byte indicates the type of device (and therefore the type of status packet) that is being transmitted.
Checksum is a simple sum of all bytes (not including the 9th bit)
The MATE asks for a status page once per second, except for the FLEXnet DC status pages 0D..0F which are only queried when a particular screen is shown.

This status packet is quite tightly packed, and the signed integers are not your typical 2's complement.
Also, the LCD cannot display all possible values and will truncate the top digit. In practice these undisplayable values should never be encountered.
If bit7 in byte[0] is 0, then AH is not displayed in CC TOTALS screen. Presumably this is because the LCD can't display negative AmpHours, but the value is signed? Either that or there is a flag jammed into the upper nibble.
Aux Mode is bits 0..5 (0x3F), Aux State is bit 6 (0x40)

The FLEXnet DC power monitor has multiple status pages, which are queried and combined. Pages 0A..0C are queried once per second, while pages 0D..0F are queried only every ~13 seconds.
Pages 0A..0C should be combined before parsing, as some values straddle adjacent pages.
TODO: The following is unaccounted for:
- Shunt A/B/C enabled flag
- Battery temperature
- Status flags
- Charge factor corrected battery AH/KWH
