How to interpret VE.direct serial output

I have a Victron BlueSolar MPPT 75/10 Charge Controller and am connected to the serial console and am having trouble figuring out exactly what the output means. I have looked at various documents and posts but none seem to match the output I am seeing:


PID 0xA04C

FW 116

SER# HQ1803BV4I4

V 12600

I -150

VPV 15060

PPV 1

CS 3

ERR 0

LOAD ON

IL 200

H19 0

H20 0

H21 20

H22 0

H23 0

HSDS 0


I am guessing V is the battery voltage and VPV is the voltage on the solar panel but I am unsure about the rest. Is I the panel current or the battery current? If its negative does that mean that the load is pulling -150 mA from the battery? What are all the H#s?


Any guidance is appreciated! Thank you.

This is what I found about the output:


PID 0xA043 -- Product ID for BlueSolar MPPT 100/15
FW 119 -- Firmware version of controller, v1.19
SER# HQXXXXXXXXX -- Serial number
V 13790 -- Battery voltage, mV
I -10 -- Battery current, mA
VPV 15950 -- Panel voltage, mV
PPV 0 -- Panel power, W
CS 5 -- Charge state, 0 to 9
ERR 0 -- Error code, 0 to 119
LOAD ON -- Load output state, ON/OFF
IL 0 -- Load current, mA
H19 0 -- Yield total, kWh
H20 0 -- Yield today, kWh
H21 397 -- Maximum power today, W
H22 0 -- Yield yesterday, kWh
H23 0 -- Maximum power yesterday, W
HSDS 0 -- Day sequence number, 0 to 365
Checksum l:A0002000148 -- Message checksum

This is the best documentation I could find on the serial output of the various devices, using the ve.direct protocol:


https://www.sv-zanshin.com/r/manuals/victron-ve-direct-protocol.pdf


Of particular note are the entries that correspond to the "MPPT" column on pages 4 and 5.
