Still in idling mode after being pulled from set-up last month for COVID.
Sites deployed:
s1 - Barometer not reporting (configuration?). Station only comes up when batteries fully charged. (Had worked ok initially after setup.). Sometimes, files are not opened. Most of the time the time stamp is bad.
P.S. Site was visited by Leila and Charles on 18 Apr. They replaced batteries and Victron, which brought power up to DSM and sensors, but DSM still hasn't come up. This suggests either a fault or wrong setting (mode 4 instead of mode 3?) of the old Victron. Dan things the next step is a DSM change, but the DSM was swaged closed so the PIs couldn't get into the box. A DSM issue is odd, though, since it was working last week.
s3 - TRH died in rain on 6 Apr. Otherwise ok
s4 - ok
s8 - EC150 never installed. GPS not receiving most messages as of 14 Mar(!). (At that time, about 13 Mar 23:30 nsat drops from 10 to 7, then further drops to 0 about 14 Mar 02:30.) Otherwise ok
s10 - ok
s14 - Mote data never worked properly, last data on 3 Apr. Cable from DSM to mote found to have water during site visit by PIs on 11 Apr, but didn't have spare. Barometer highly intermittent (but Pirga ok). Otherwise, ok.
s15 - ok
s17 - Site pretty much never worked. Just a few hours of data early on. Last data 26 Mar. From log snapshot taken when station was last up, seemed to be a DSM USB issue.

When running and last connected, the (old) Victron message was:

Since ERR=0, it is happy. Load is on at 1200mA, PV input is 39.5V, system voltage is 13.5V – all just fine. I = 210mA means that only a little more than load is being used, so batteries are mostly charged. CS=5 means in "float" mode, consistent with the batteries being fully charged. MPPT=1 means "voltage or current limited". I don't see a "mode" report to indicate which program it thinks it is using.
From the VE.Direct Protocol:
CS The state of operation. See the table below for the possible values.
MPPT Inverter Off 0 • •
Low power 1 • (load search)
Fault 2 • • (off until user reset)
Bulk 3 •
Absorption 4 •
Float 5 •
Inverting 9 • (on)
and:
MPPT The possible values for the tracker operation are listed in this table.:
Off 0
Voltage or current limited 1
MPP Tracker active 2
The last message before the station died was a bit different:
PID\t0xA05F\r\n
FW\t146\r\n
SER#\tHQ1901UCJCE\r\n
V\t8640\r\n
I\t190\r\n
VPV\t35200\r\n
PPV\t16\r\n
CS\t4\r\n
MPPT\t2\r\n
OR\t0x00000000\r\n
ERR\t0\r\n
LOAD\tON\r\n
IL\t1600\r\n
H19\t1168\r\n

HSDS\t37\r\n
ERR still is 0 and PV is at 35.2V, but V has dropped to 8.6V and Iload increased to 1600mA (probably due to the lower voltage). Now CS indicates "absorption" – trying to charge (though I is still only 190mA) and MPPT=2 ("MPP tracker active").
