Can you stack an EG4 3 slot battery rack on top of an EG4 6 slot rack? More specifically can the busbar of the 3 rack be connected to the busbar of the 6 rack, which is then connected to the inverter?
E775 did a video where a customer stacked the 6x racks on top of each other-custom modded them with all thread rod to connect and secure them. Something like 217kW of them
Maybe if you review it in detail you can glean some info on how they strung the actual batteries and bus bars together.
