Write the control firmware for every SST cell and block: modulation, closed-loop voltage and current control, and voltage sharing across dozens of series-stacked cells. Build the fast protection path that detects a fault and shuts the converter down within microseconds, from sensing to safe state. Sequence startup, precharge, cell bypass, and the reconfiguration of the output from 800 V to 1,500 V. Connect cell controllers to the block master and the site control system across isolation barriers, with telemetry operators can act on.
