suntwins 5000TL

[GoogleCodeExporter]

Using solarmonj with a Suntwins 5000TL unit is giving me incorrect readings.

I've captured data to CSV as follows:

1396162955,35.7,18,25.76,384.7,242.2,0.7,4.78,0.8
1396163135,35.6,18,27.12,389.2,283.4,0.7,4.8,0.8
1396163218,35.5,18,26.77,368.5,288.1,0.6,4.81,0.7

According to main.cpp the column order is:

now  << "," <<   data.temperature << "," << data.energyCurrent << "," << 
data.energyToday << "," << data.energyTotal << "," << data.voltageDc << "," <<  
   data.voltageAc << "," << data.frequency << "," << data.current

The 4th column, 'data.energyToday' went backwards on the last reading (from 
27.12 to 26.77). I would expect that counter to always increase. Am I 
mis-reading this?

The other problem is that the values do not match the readout from the unit's 
LCD display. For example, the LCD says 'ETot 301' whereas the corresponding CSV 
values (data.energyTotal) are all higher than this!

Is anyone else using solarmonj with a Suntwins 5000TL?

After some tinkering, I discovered that the values I was getting were correct 
however in the wrong order. I've attached a patch to fix that.

As far as I can tell, my inverter does not provide a reading for the total 
energy generated. It does however provide a reading for 'PAC' (photovoltaic 
AC?). My patch removes field 'energyTotal' and adds field 'pvoltageAc'.

I have the same issue, will try your patch and compare.

FYI, the 'frequency' value needs to be divided by 100. I've updated the patch.

Hi GoogleCodeExporter,

Hope you don't mind but I have applied your patch to a branch of this repository.

Hello all.
Sorry I did not get notified as this was an exported project from Google Code.
Thanks benleov for fixing the issue. Are there any other issues here or can this be closed now?

[benleov]

No worries. I didn't fix the issue, just applied the patch that @GoogleCodeExporter created to my own branch then made a small modification to send the data out a socket which I'm reading into Elasticsearch via Logstash. You guys did all the hard work! As far as I know its working fine.
