logical and

[John Frum]

use case 0:
single fet based bms protected battery controls an inverter by way of an ssr.
The ssr is used because the inverter draws more amps than the bms can handle.

use case 1:
multiple fet based bms protected batteries control an inverter by way of a magical device which logically ands the bmss to control the ssr.

Does this magical device exist that provides power to the ssr only if both bmss are not tripped?
What is its name?
Where can I get it?

Hope that is clear.

Just use relay logic ... put 2 SSR in series ... one controlled by each BMS.

Geez I'm not even the sharpest spork in the drawer.
Thanks
