Abstract
This work targets modular nanogrids for remote locations, where photovoltaic modules can be gradually introduced to grow the renewable energy capacity at minimal capital cost, while reducing diesel fuel consumption. Today's grid-tied micro-inverters provide a modular solution for ac power generation in nanogrids but battery storage remains centralized, requiring an additional ac-dc converter. The main contribution of this work is a new micro-inverter platform and control scheme with bidirectional power flow between the nanogrid, the photovoltaic module and integrated short-term storage, using new high energy-density Lithium-Ion Capacitor technology. A real-time power smoothing algorithm is also proposed and the performance of the new 100 W micro-inverter is experimentally verified under various closed-loop dynamic conditions.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
