My system has 2 AC300 with each bank having 3 B300 batteries. I am running in split phase mode and currently charging with AC from the grid. I would like to charge by solar input and would like to know the correct way to connect. Do I have to have separate panels for each AC300? Or is there a way to charge both at the same time like I am doing now.

I have a similar setup with four B300 on each AC300. You do have to install two sets of solar panels, one for each AC300. My setup has four 400 watt panels per PV input (two per AC300), for a total of 16 panels (up to 6 kW) . Each PV can accept safely up to 150 VDC ( try to kerp it under) , and will limit current inputs to 10 A. But each PV input is limited to just 1.2 kW. Read the AC300 user guide to understand more.
Do you have solar panels already? or what are you thinking of buying?
You should be able to set it up as 2 arrays or 4 arrays depending on your panels.
Thank you. Your reply was exactly what I needed!

I am thinking of buying and trying to plan out how to design the system and what I need to purchase. I appreciate the information.
