I am looking to extend my system with another inverter. I now have a Phoenix multiplus 24/3000/70 from 2009. I have a HEX number of 1812017.
On the form I read about not being able to connect compacts, phoenix inverters and newer multi's with my firmware. My question is three fold.
1. If I am able to get another Phoenix multiplus with the a simmilar HEX number (beginning with 18) is it then possible to connect them parallel?
2. What cable do I use to connect the two? I only have 1 RJ45 port for my control panel and 2 10pin ports of witch I don't know the name. The manual says it should be possible to connect with other devices from the port. (https://www.victronenergy.nl/upload/documents/Installation%20Manual%20Multi%20and%20Phoenix%20Inverter%20(Non%20VE.Bus%20models).pdf Paragraph 1.6.6.)
3. With the correct cable, will the parallel set than communicate via the old MK2 protocol? Or do I need to install a certain protocol?
See below for pitures of the inside of my current phoenix multiplus.
