Technical writing on battery analytics and grid-scale BESS operations
Electrochemistry, fault detection, asset management, and integration patterns — from engineers who work with operator telemetry every day.
State of Health vs. State of Charge: The Operator's Guide
SoC tells you how much energy is left. SoH tells you how much the battery can still hold. Most operators track the first and ignore the second — here is why that matters.
