Not a big fan for relais or contactors, they tend to get stuck in the "on" position when activiated for months without switching.
I beleave the contactors in a EV switch off when the contact is off, so they toggle often,while in a powerwall type ofsetup, they will only switch off if there is a critical event. ( so in best case never )
Only kind of downsidewith the shunt trip activated breakers is, there is no way to "remotereset" them onceactivated ... they have to be manual re-activated, in my mind this is not a negative thing but a plus for safety...
Interested in the value/rating of this - do the Leaf's normally have a high voltage pack?Sean said:Relays A/B are buss connects, relay C is for the 30 ohm 40 watt precharge resistor.
