I have seen several comments/questions regarding the use of the expansion batteries along with the 500pro. I get that the Pro will not charge the B300. I guess what i do not understand is why you say it will not expand the capacity? If I am drawing power out of the Pro and have the B300 plugged into the 500Pro input with the P090D-MC4, won’t it charge the 500Pro as the power is drawn out through the Pro output? What is the difference between this and “expansion” just trying to understand.
Thanks!

Hi @shirschhorn
The B300 act as power income source. Like PV or AC input.
So it will charge the EP500Pro but you cant charge the B300 the same way. It doesnt work like a AC300 for example. Its just a simple input for EP500Pro, just one way.
Powerstation like the AC300 with expansion batterys work two way. You can charge and discharge it from the same connection.
The B300 can be combined with a T500 AC adapter. In this case you can charge your B300 when have enough sun and discharge it when needed.
Does this answers your question?
