The inverter used is a bi-directional inverter that facilitates the storage to charge from the grid as well as from the PV. This configuration is similar to DC coupled, but the storage can be charged using PV only, not from grid electricity. This is also known as the DC tightly coupled configuration.
BESS is charged by converting the PV electricity from DC to AC and then back to DC at the BESS inverter for the BESS to store it. Since there are no shared components, the storage can still act independently of the PV system.
The next step in the battery manufacturing process is calendering, which acts as the finishing process for the coated rolls. Like the previous step, it is a roll-to-roll process, where the coated rolls travel through two heated rollers to compress the material and thus, ensure constant thickness, density and better adherence. 1.4.

As mentioned at the beginning, the battery production industry is also characterised by its high degree of digitalisation and automation, which are key for process optimisation and productivity. Thus, solutions based on machine learning and artificial intelligence will be very common in the future gigafactory generations.
