This is the reverse kind-of thing. I have an arduino with a canbus shield talking to a Venus-GX (in this application it is pretending to be a battery, it makes it possible to test code with all sorts of rubbish in the can frames). But you could easily reverse it and have it talk to a battery using the CAN-bus.

Just a few things to remember when installing a Ziehl 
You will need the following:  AND One or two 63A contactors  
 
Install using the following connection diagram.    Please remember to bridge L1 - L2 - L3 when single phase are used.  Return wires (Feedback from Contactors) are not required in SA. I have used 48VDC to power the unit, but you can can chose to use the grid voltage. I have used grid voltage to switch the contactors.  I have Chosen 63Amp Din rail mount DB contactors (Schneider)   
Putting the unit into programming mode: Switch the supply on.  Look at the following picture.  The unit comes with the seal not in place.  If the Led between the 2 locks are Red, slightly lift the key cover and turn it 180 degree. While turning you will see a Small blue pin like switch behind the key cover.  Use the key cover and press down firmly on the blue pin for 2 seconds.  The Led should turn to Green now.   Once the LED is Green you can continue with the configuration.   
Configuration: There are 2 Programs to chose from PRG5 is used for 230Volt Phase to Neutral, 1 or 3 Phase PRG6 is used for 400Volt phase to phase systems with no Neutral.  Press the UP arrow 1 time to display "InFo." Press the RIGHT button 5 times to display "PR 1" Press the UP button till you reach "PR 5" or "PR 6"  Press the RIGHT button 1 time to display "no" Press the DOWN button 1 time to display "YES" Press the Right button. The Device will reset and start with the new program.  Every time a new program is selected, all the settings revert to the default settings.  Changing Settings:  ONLY after you selected the relevant program for your installation, you should continue to the settings.  Press the UP button 2 times to get to the first Menu on the Settings LIst.  Use the Right Button to Scroll through the 5 settings of each Parameter. Use the UP and Down buttons to change the setting to mach the settings on the list.  Once done with all 5 settings, use the UP button to scroll to the next Parameter on the list.   The settings for South Africa are as follows.  Once you done, remove and re-apply the power, the unit will go through a 60 Second "self check" that might be followed by another count down.  Once that is complete and all conditions are within spec, the Contactors should energize.  Once you are satisfied with the settings, press the blue pin till the LED turns red.  Apply the seal, but dont crimp it till you are sure no one wants to check your settings.    

ABB has sold their solar manufacturing facilities to FimerSpa. This includes all three R&D centers as well as the Power-One factory where the string inverters are manufactured. As for the products, they are still exactly the same and operate with the same functions and still 100% compatible with Victron. Only the name changes. We were the technical partner for ABB string inverters in Sputh Africa and we are now the technical partner for FimerSpa.
When trying to decide whether to use AC or DC coupled, you have to look at a couple of things. What time of day is your load mostly. How big is you system and to an extent, what size battery do you want to put in.
