Controllers, switchgear and storage for commercial microgrids, sourced as an islanding-capable system rather than a standard grid-tied one with backup bolted on.

Source controllers, switchgear and storage for commercial microgrid and resilience projects. Islanding-capable equipment sourcing on Sunhub.
A true microgrid needs a controller that can detect a grid outage, disconnect safely and manage generation and storage while islanded, a different capability than a standard backup-rated inverter. Sourcing here filters for that distinction.
Automatic transfer switches and protective relays get sourced to the specific voltage and current the site's islanded operation requires, not a generic backup panel.
A microgrid's battery has to carry the site through an outage of a defined length, which is a different sizing exercise than demand-charge storage even at the same site.
Controller and switchgear selection targets real islanding capability, not a backup system marketed as one.
Battery capacity is set against how long the site needs to run islanded, not a generic capacity target.
A microgrid adds the pieces that let it run disconnected from the utility, primarily an islanding controller or microgrid controller, switchgear or a transfer device rated to isolate from the grid automatically, and storage sized for the outage rather than just peak shaving. Protection, metering, and controls that coordinate generation and loads during an island round out the package. Sourcing these as one islanding-capable system, rather than bolting backup onto a grid-tied design, avoids integration gaps.
It detects a grid outage, safely disconnects the site from the utility, and manages the transition to running on local solar and storage without dropping critical loads. During the island it balances generation against demand, keeps voltage and frequency stable, and reconnects cleanly once the grid returns. This is the control layer that turns solar plus batteries into a system that genuinely keeps running through an outage.
In many cases yes, but it is rarely a simple add-on. You typically need to add an islanding-capable inverter or controller, transfer switchgear, and storage, and confirm the existing array and interconnection can support island operation. The economics and complexity depend on how the original system was designed, so an upfront assessment of what carries over and what must be replaced is worth doing before committing.
