P6) 416 OFPPk (Power Configuration)
416 POWER CONFIGURATION
With Power configuration, the capacity will be double as it adds more parallel packs to the existing configuration. When the stack increase, it can be rotated for a direct back to back mounting. Still using back the 10 screws.. is that simple. No wire or cable is needed.
(Option screws is required)

Note: Please note that there'll be some losses thru cables and connector when amperage goes high.
Capacity is greatly depends on each battery rating. Using higher rating with similar configuration will result in higher overall capacity and vice versa.
BMS (Battery Monitoring System) is a critical part of this system. It monitors and control the balancing of voltages across all the packs in the system. Balancing is needed for Lithium batteries to protect from operating outside its safe operating range. Selecting a good BMS with rated capacity is a MUST on a big system like Powerwall.
