Just found a second hand B300 and need to know:
Can I connect my AC500 to a B300s and a B300 together?
I need an adapter wire, must I plug that into the AC500, or can it be daisy chained in the B300s too?
Will this limit the max wattage of my AC500?
To connect the B300 to the AC500, you need an extra P150D to P090D cable.
AC500+1* B300, max charging power is 3000W
AC500+2* B300, the max charging power is 5000W.
Interesting. In order to reach 5000W with 2* B300, do you need 2* P150D to P090D ? Or is 1 enough as in the following ASCII diagram shows, connecting the B300 with their default cable?
[AC500] === (P150D to P090D) === [B300] === (basic P90D cable) === [B300]
Right. You’re wired the right way. One P150D to P090D cable is fine.
Interesting. Especially since it seems that the self-heating feature is only available when the battery is connected to a grid, correct? Grid, or simply put, an AC source.
Only the B300S has automatic heating, B300 does not.
Sorry, I took a shortcut in my phrasing; I meant, since B300S needs to be connected to an AC source to benefit from its self-heating feature, it makes B300 more attractive in my case since I don’t have an AC source where I plan to install the AC500… so for a lower price tag, adding a B300 seems like a better option.
That’s been my thinking as well. My AC500 came with a B300S and since then I’ve added two B300’s. The only downside is if I wanted more than four batteries it wouldn’t work.
The self-heating function of B300S can be activated by AC or PV charging.
Thanks, good to know. PV charging from either AC500 or B500, or only one of them?
Self-heating function can be activated by charging the B300S with PV, without the need for an additional AC500 connection.
Excellent, this makes a huge difference
