Well ya’ll got me nervous. I was excited because I didn’t like the idea of connecting the 460w panel to ONE battery…and not the other. I was concerned it would result in one battery aging differently than the other. So, sharing the over wattage between the two 200w inputs seems logical.
.
So, what might happen if it goes wrong? What does “mess up both” look like?
.
Is there an economical solution that could take the single PV outputs, and manage sending out the right amount of power to the B300 batteries? In other words, something other than a Y on the wires hoping the right amount goes to the right place?
.
Thanks!

There is a simple way to check that it is working properly when your additional panel is under the sun, and the b300 are connected in parallel with the y cables: disconnect the b300 from your ac300 (to be sure that they are not charged by your ac300) and observe the green LEDs on your 2 b300. if they both run (chasing) at the same rate, regularly, it is working!
I’m thinking about it to see if there is another solution! (I don’t see any at this stage)
