The old version (1.7.x) of my app worked with a tristar last summer, I haven't had a chance to test the version 2.x of the app with a real tristar.
The app will try to access modbus register 4101, if it succeeds then it assumes a classic, if it fails then it tries address 0001 (triStar) if that succeeds then it assumes it's a tristar.

Graham,
Do you have a modbus register map for the mppt Tristar or can you point me where to download it?
The only one I can find is corrupted and the d/l fails

Do you mean this one dgd ? It just downloaded for me .

Thanks, thats it.
I needed to update adobe reader then it worked ok

Did you try restarting your classic ?
Seems like it took me awhile to get it to work or for it to show up on the new webpage. But I didn't know what I was doing so not sure exactly what made it finally show up .

I think Andrew has said in the past that any changes to the network parameters requires the Classic to be restarted. I wouldn't think that for effect the username/password not working on the new site. Just wouldn't see the Classic logging data.

Maybe set the Classic for auto restart at 23:59

The network parameters are weird -- in fact most changes do not require a restart; however, the DNS settings, for some unimaginable reason, I did differently from the other settings and so any changes to the DNS settings (including setting the classic FROM STATIC to DHCP resulting in getting a new DNS server from the DHCP server) will require a reboot. I believe I rectified this in the latest network code but we still haven't released this for general consumption yet.
Sorry for the mess.

Here are the registers I use for Tristar, the values need to be converted using the scaling factor found in register 1 & 3

Register[] registers = modbusMaster.readMultipleRegisters(0, 80);
                if (registers != null && registers.length == 80) {
                    readings.set(RegisterName.BatVoltage, VScale(registers[24].getValue()));
                    readings.set(RegisterName.PVVoltage, VScale(registers[27].getValue()));
                    readings.set(RegisterName.BatCurrent, IScale(registers[28].getValue()));
                    readings.set(RegisterName.PVCurrent, IScale(registers[29].getValue()));
                    readings.set(RegisterName.Power, PScale(registers[58].getValue()));
                    readings.set(RegisterName.EnergyToday, WHr(registers[68].getValue()));
                    readings.set(RegisterName.TotalEnergy, (float) registers[57].getValue());
                }

    private float WHr(float val) {
        val /= 1000;
        return val;
    }

    private float PScale(float val) {
        val = val * v_pu * i_pu;
        val /= 131072;
        return val;
    }

    private float VScale(float val) {
        val = val * v_pu;
        val /= 32768;
        return val;
    }

    private float IScale(float val) {
        val = val * i_pu;
        val /= 32768;
        return val;
    }

                if (registers != null && registers.length == 4) {
                    foundTriStar = registers[0].toShort() != 0;
                    if (foundTriStar) {
                        float hi = registers[0].toShort();
                        float lo = registers[1].toShort();
                        lo = lo / 65536;
                        v_pu = hi + lo;

                        hi = (float) registers[2].toShort();
                        lo = (float) registers[3].toShort();
                        lo = lo / 65536;
                        i_pu = hi + lo;
                        reference = 0;
                    }
                }
            }

Thanks Graham
Those registers are all I probably need to get the Mppt Tristar interfaced via modbus RTU to my Arduino DUE web server. One of my customer sites has an unused  mppt60 since I installed a Classic 150 last year, time now to borrow it and start playing

BTW
these offsets are origin 0 so register[24] is modbus register address 25 (I always get this wrong...)

here is a table I used in my netduino project with the address @ origin 1

// TriStar modbus table
//            new Register { Address = 1, Label = "V Scale", UnitOfMeasure = "", Conversion = socketAddress => U32(socketAddress)},
//            new Register { Address = 3, Label = "A Scale", UnitOfMeasure = "", Conversion = socketAddress => U32(socketAddress)},
//            new Register { Address = 25, Label = "Average battery voltage", UnitOfMeasure = "Volts", Conversion = socketAddress => VScale(socketAddress)},
//            new Register { Address = 28, Label = "PV input voltage", UnitOfMeasure = "Volts", Conversion = socketAddress => VScale(socketAddress)},
//            new Register { Address = 29, Label = "Average battery current", UnitOfMeasure = "Amps", Conversion = socketAddress => IScale(socketAddress)},
//            new Register { Address = 30, Label = "Average PV current", UnitOfMeasure = "Amps", Conversion = socketAddress => IScale(socketAddress)},
//            new Register { Address = 45, Label = "Info flag", UnitOfMeasure = "", Conversion = socketAddress => Info(socketAddress)},
//            new Register { Address = 51, Label = "Battery charge state", UnitOfMeasure = "", Conversion = socketAddress => ChargeState(socketAddress)},
//            new Register { Address = 58, Label = "Total kWhours", UnitOfMeasure = "kWh", Conversion = socketAddress => U16(socketAddress)},
//            new Register { Address = 59, Label = "Average power to the battery", UnitOfMeasure = "Watts", Conversion = socketAddress => PScale(socketAddress)},
//            new Register { Address = 69, Label = "Average energy to the battery", UnitOfMeasure = "kWh", Conversion = socketAddress => WHr(socketAddress)}

//            new Tupple { Description = "(Start) System startup.", Value = 0 },
//            new Tupple { Description = "(Night check) No power, detecting nightfall.", Value = 1 },
//            new Tupple { Description = "(Disconnected) No power.", Value = 2 },
//            new Tupple { Description = "(Night) No power, waiting for power source.", Value = 3 },
//            new Tupple { Description = "(Fault) Detected fault.", Value = 4 },
//            new Tupple { Description = "(Bulk) Max power point tracking until absorb voltage reached.", Value = 5 },
//            new Tupple { Description = "(Absorb) Regulating battery voltage at absorb set point until the batteries are charged.", Value = 6 },
//            new Tupple { Description = "(Float) Max power point tracking. Seeking float set point voltage.", Value = 7 },
//            new Tupple { Description = "(Equalize) Regulating battery voltage at equalize set point.", Value = 8 },

Is it possible to  have the PVoutput transfer work if using your app with BlueStacks? Are the daily logs save somewhere when using BlueStacks?

It's the first time I hear about BlueStacks, I'll try it later this week.
Are you on Windows 7?

I finally got around to testing the app under bluestacks with the pvOutput upload

I ran wireshark to monitor the ip.dst==pvoutput.org with the test site http://pvoutput.org/list.jsp?id=30606&sid=28034

it took a couple of minutes to get started but it worked,
you can clear the log file in the app in the settings and try the upload again by restarting the app after pressing clear logs...

Clearing the logs seem to be the trick. Thanks Graham
