Microgrid Controller
The intelligence layer of a residential microgrid — a dedicated power management computer that monitors all energy sources and loads in real-time, optimizes battery state of charge, decides when to start/stop generators, manages power flow between sources, executes load shedding if needed, and enables remote monitoring. A microgrid controller is what distinguishes a true microgrid from a collection of independently operating devices. Consumer battery products use basic inverter logic, not a dedicated controller.

An operating state in which an appropriately configured property electrical system is isolated from the utility grid and supplied by local resources such as storage or generation. Island-mode capability, transition behavior, supported loads, and runtime depend on system architecture, approved protective equipment, available energy, and site conditions.
The intentional, controlled reduction of electrical consumption to match available generation capacity. Executed automatically by a microgrid controller during low-generation periods (cloudy days, low fuel) or high-demand spikes. Load shedding prioritizes critical loads and temporarily suspends lower-priority loads (pool heaters, EV charging) to maintain system stability. Prevents battery depletion during extended outages.
The current energy level of a battery bank expressed as a percentage of total capacity. Example: a 40 kWh battery at 75% SOC holds 30 kWh of usable energy. Microgrid controllers continuously monitor SOC and use it to make operational decisions — when to charge from solar, when to start the generator, and what minimum SOC floor to maintain for emergency reserve.

Customer-sited generation + energy storage + backup generation + intelligent controls = whole-property power continuity.
