Negative power = charging into battery; positive = discharging out of battery.
Battery (emerald), DC side (amber), AC side (rose). Sustained battery temp > 35 °C in cool ambient suggests heavy cycling; sustained inverter temps > 60 °C suggest poor ventilation.
Each full cycle ≈ one full charge + full discharge. Lithium chemistries are typically rated 6000+ cycles to 80 % capacity.
Lithium chemistries are healthy at 90–95 %. Sustained downward trend suggests cell aging.
Healthy cells trace a tight, repeatable curve. Widening cloud suggests cell imbalance or sensor drift.
The purple bar shows the daily SOC sweep. Shallow cycles (small purple bar high up) = long battery life; deep cycles (tall bar reaching low) = aggressive use.
