Has anyone been able to confirm compatibility with newer hybrid Infinisolar VII 6kw split phase?

[derekyle]

I have a SunGoldPower BluePower TP6048 which I believe is the same as the Voltronic Infinisolar VII and also the MPP Solar LVX-6048. I have been testing with a project that I believe is based on this one, and someone there confirmed it working for a Voltronic Axpert King II 5kva, which looks identical on the outside but has slightly lower specs and is off-grid only. All commands I send are being responded to with NAK (rejected). I am inclined to think that this unit would be using the same protocol as the Axpert King II. But I have not been able to find any confirmation from anyone else that my particular unit or the other brandings of the same unit are working on the same P18 protocol.

Try a QPI command using the default PI30 protocol and see if you get a result

[smrruby]

On my LVX6048 here is all I get from QPI

root@raspberrypi:/home/stever # mpp-solar -p /dev/hidraw0 -c QPI
Parameter                       Value           Unit
error                           NAK

[derekyle]

QPI command on the PI30 protocol gives a NAK response. However, everything seems to be working great with the PI18 protocol!

mpp-solar -P PI18 -c GS

Gives a nice general status report and the commands for changing battery status priority seem to work as well. So for anyone else that might be looking for this issue, the SunGoldPower BluePower TP6048 is confirmed working with protocol PI18. I also believe that this is an identical unit to the Voltronic Infinisolar VII and the MPP Solar LVX-6048, so I would say there is a very good chance they all use the same protocol and will work as well.

[smrruby]

I have the MPP LVX6048 inverter and I'm having a hard time getting data out of it. I want to get to PV power, battery voltage, charge current, etc. but I'm getting "NAK" in some responses even though some seem to have limited information.

I tried the suggested PI18 example from @derekyle above but I only get this:

root@raspberrypi:/home/stever # mpp-solar -p /dev/hidraw0 -P PI18 -c GS

the best I can get out of it is this for live status, which seems to indicate am really talking to the inverter.
mpp-solar -p /dev/hidraw0 --getstatus

fair enough
seems like the right protocol, interesting that you get 0 volts for the battery
lets see what it gives when the SCC is on

[smrruby]

Do you know if the LON1 command should be able to turn on the inverter (equivalent of pushing the silver button on the display)? If I could turn on the inverter remotely that would help with some of my use cases and need. And if I could turn on the inverter right now I would expect it to go into more of a normal operating condition. It appears that the function is with no solar, inverter off, battery only that the inverter is off (no display, no wifi connection) at night and comes up (display on and wifi connected) when it gets to 120Vdc solar or so. Except that if a USB cable is connected it powers it up enough to show error "32" on the screen and it is generally (as you see) in a responsive state. Seems as though the 5v USB connection is powering something. it says the "SCC" is powered up in the --getstatus query but I'm not sure what that means

warning0                        Command LON1 was rejected

the vendor said that I should be able to turn it on or off by shorting across some pins in the display panel's RJ45 connection but he hasn't been able to provide documentation.

[jblance]

i dont know sorry. i have no first hand knowledge of this particular inverter
i think someone else was having trouble with that (and other) commands that should work according to the docs

[smrruby]

I am getting a battery voltage and some other reasonable values from the GS query now that the sun is up.

Hello. What is SCC ?

[jblance]

Good news Looks like this protocol could do with an update to get the value correct (ie change from 0.1v to v as the unit and correct report the voltage) I wonder how many others would get broken....

I have the LVX6048 and noticed there seems to be a "GS2" command the SolarPower windows program uses to pull information about L2. Prefix is "^P006". The response seems to be padded with zeros. I have a custom protocol written for myself that gets the job done. I might be able to get more wireshark captures if that helps anyone.
Example Response:
b"^D0781259,0000,600,000,1200,0000,600,000,0216,0000,0135,0000,007,000,0000,0000,0\xefx\r"

[jblance]

Do you have the info on what each item in the response is?
