I have a question: As far as I know more than one battery can be connected in parallel. How will they be connected to each other and how with the inverter or maybe multiple inverters ? All red poles connecting together and putting this red cable on the inverter(s) and the same with the black poles. Right ?

yes , they are new batteries . If you need , welcome to contact me . Whatsapp: +86 18759902085 Thanks

I have just installed one of these batteries and the inverter. There are no instructions with the battery. Does it need communication links to the inverter? RS232? RS485? What should the DIP switches be set to? Also instructions should be written in much clearer English. Much of the text is difficult to read as it seems to have been generated by Google translate and not an English speaker.

I've got four inverters and 4 batteries. Each package had one additional cable for the communication. So YES, you need the cable. In my case I need only one cable for all inverters and batteries because the version of inverters I have handles that through the communication cable between the inverters 🙂
