I'm unable to get any useful date out of my SB3000TL-21. It always says date 
error.

What steps will reproduce the problem?
1. ./smatool -v
2.
3.

What is the expected output? What do you see instead?
I always get date error!

What version of the product are you using? On what operating system?
Raspberry pi, wheezy image

Please provide any additional information below.
I have 2x SB3000Tl-21 (NETID2 and NETID3)
FW Version 2.50 HP 2.10

I forgot to add the output from smatool

Thanks!

Did you have correct time on je RS PI set?

I was not able to fix this yet. I also tried changing the inverter code.

You may be right about the time not being set correctly on the ras pi. I can 
try fixing this.

The time on the raspberry pi was off by two hours (too early), but it does not 
seem to help.

Also in order go get the above error i had to make sure my two inverters did 
not have the same NETID, otherwise i was unable to get anywhere. When using 
sunny explorer, the inverters have the same NETID as they are read as 1 plant.

I'm up and running with my Raspberry Pi <-> 4000TL-21 inverter !

Later this evening I will give a more detailed explanation about how I managed 
to get it to work.
For now some bulletpoints:

 - add correct inverter details in invcode.in
 - smatool.conf -> comment out lines of date error (maybe not needed)
 - smatool.conf -> change interval on line '?' to 13
 - rm smatool  -> make smatool -> split smatool
 - create script sma-cron.sh (file will be attached)
 - setup crontab (each 5 minutes) (don't forget to restart cron /etc/init.d/cron restart)
 - uncomment "cron" line in /ect/rsyslog.conf (!! /etc/init.d/rsyslog restart) -> maybe not needed

Looking forward to more details later this evening.

Does anyone know specifically which inverter code to use for SB3000TL-21?

I tried the default value for SB3000TL aswell as

"Codes for SB3000TL-21 Code1=9b Code2=8e Code3=e2 Code4=37 InvCode?=8a "

Oke, here we go:

In my case, the sma-bluetooth files are located at /home/pi/smatool

- add correct inverter details in invcode.in

  I added:
     Inverter        SB4000TL21
     Code1           0x38
     Code2           0x4f
     Code3           0xce
     Code4           0x35
     InvCode         0x8a

- smatool.c -> comment out lines of date error (maybe not needed)

      /*if( idate != prev_idate+300 ) {
          printf( "Date Error! prev=%d current=%d\n", (int)prev_idate, (int)idate );
          error=1;
          break;
      }*/

- smatool.c -> change interval on line '?' to 13 (maybe not needed)

$ on dd2.DateTime=DATE_FORMAT(dd1.DateTime,\'%%Y-%%m-%%d 00:00:00\') WHERE 
dd1.DateTime>=Date_Sub(CURDATE(),INTERVAL 13 DAY) and dd1.PVOutput IS NULL and 
dd1.CurrentPower>0 ORDER BY dd1.DateTime ASC" );

- rm smatool  -> make smatool -> split smatool

  remove and rebuild the smatool by following commands

  rm smatool
  make smatool
  split smatool

- create script sma-cron.sh (file attached)

    don't forget to change the parameters

- setup crontab (each 5 minutes) (don't forget to restart cron /etc/init.d/cron 
restart)

    - crontab -e  and add ...

      # m h  dom mon dow   command
      */5 * * * * /home/pi/smatool/sma-cron.sh > /dev/null 2>&1

    - restart cron
       /etc/init.d/cron restart

- uncomment "cron" line in /ect/rsyslog.conf (!! /etc/init.d/rsyslog restart) 
-> maybe not needed
   might be handy to check if cron is working

- logfile.log will be created if faulty data is found

I hope this will help you guys !!!!
