Thanks Zsde, but i was never able to connect to RS232A on the device. It's a special cable, and serial to usb converter. As such, i was never able to change the battery protocol. 
I needed a dsub-9 to rj11, and i don't have either end at home, but the serial to pi, and pi to ICC option at least i had all the parts. 
 

Here is the document from Svolt explaining in detail how to communicate with different Inverters.

Renier, no, the inverter and the battery seem to speak past eachother. 
I have an ICC installation on a raspberry pi which speaks to both, so i can monitor battery and inverter using the same online portal, works rather well.

I had to get a serial to USB converter for the battery to pi connection. 
This is similar to the way the hubble BMS setup works.
