QPIGS update for PV power for a 2424LV

[nigel16494]

I needed the PV input power from the panels so I changed the QPIGS a little at the end to add some extra fields and fix the unknown byte issue, it seems to be working OK now for several weeks.

My qpigs.json is { "name": "QPIGS", "description": "General Status Parameters inquiry", "help": " -- queries the value of various metrics from the Inverter", "type": "QUERY", "nosupports": ["LV5048"], "response": [ ["float", "AC Input Voltage", "V"], ["float", "AC Input Frequency", "Hz"], ["float", "AC Output Voltage", "V"], ["float", "AC Output Frequency", "Hz"], ["int", "AC Output Apparent Power", "VA"], ["int", "AC Output Active Power", "W"], ["int", "AC Output Load", "%"], ["int", "BUS Voltage", "V"], ["float", "Battery Voltage", "V"], ["int", "Battery Charging Current", "A"], ["int", "Battery Capacity", "%"], ["int", "Inverter Heat Sink Temperature", "Deg_C"], ["int", "PV Input Current for Battery", "A"], ["float", "PV Input Voltage", "V"], ["float", "Battery Voltage from SCC", "V"], ["int", "Battery Discharge Current", "A"], ["flags", "Device Status", [ "is_sbu_priority_version_added", "is_configuration_changed", "is_scc_firmware_updated", "is_load_on", "is_battery_voltage_to_steady_while_charging", "is_charging_on", "is_scc_charging_on", "is_ac_charging_on" ] ], ["int", "RSV1", "A"], ["int", "RSV2", "A"], ["int", "PV Input Power", "W"] , ["flags", "Device Status2", [ "is_charging_to_float", "is_switched_on", "is_reserved"

Hope this helps

great thanks - can you run a QPI command mpp-solar -c QPI (add any device / model parameters as needed) This is because I think the different protocol versions have slightly different responses and I am trying to put together a better way of choosing the correct response definition

So, maybe the tool checks QPI first then selects the right response definition from there (ie my 4048 gives PI30)

[nigel16494]

pi@raspberrypi:~ $ mpp-solar -c QPI -d /dev/hidraw0 protocol_id PI30

Also I was doing some fuse and rewiring work and so I could test the "unknown byte" flags. I found that it works also. is_switched_on 1 ---> when my inverter is on is_switched_on 0 ---> when my inverter is off

Let me know how I can help further.

Thanks, Nigel

Great thanks Have added this change to the repo Cheers John
