Scalability / Modularity
The ability to expand a power system's capacity by adding additional modules — battery strings, solar arrays, or generation units — without replacing the existing architecture. LFP battery systems are generally modular; new battery cabinets can be added to expand kWh capacity. Inverter and controller platforms must support the expanded capacity. Scalability is relevant for estate owners whose electrical loads grow over time (EV chargers added, home additions, new pool equipment). A properly specified microgrid architecture accounts for planned future expansion.

On-site electrochemical energy storage that allows a property to store electricity and discharge it on demand. In a microgrid, storage may support backup operation, energy buffering, and reduced generator runtime. Transfer behavior depends on the selected equipment, system design, and operating conditions. Storage is sized in kWh for energy capacity and kW for power output; both metrics affect supported loads and duration.
A power electronics device that converts DC (direct current) electricity — from solar panels or batteries — to AC (alternating current) electricity that home circuits use. In a microgrid, inverters are bidirectional: they can also convert AC grid power to DC to charge batteries (operating as a rectifier). Inverter capacity sets the maximum AC output a battery system can deliver. A 10 kW inverter can sustain 10 kW of continuous AC output regardless of how large the battery bank is. Inverter selection is a critical engineering decision — residential microgrids typically use multi-mode inverters capable of grid-tied and off-grid operation simultaneously.
