Solar Microgrids

One network. Coordinated power.

Bring local generation, storage and multiple loads under one control strategy—for campuses, communities and sites that need a defined path to energy resilience.

A microgrid is a system—not just a larger array.

A microgrid coordinates interconnected loads and energy resources within a defined electrical boundary. It may operate with the utility grid or independently. Its controller, protection scheme and ability to establish a stable local supply are as important as the generation capacity.

Generation. Demand. Engineering.
01

Campuses & institutions

Multiple buildings with a shared strategy for essential services, generation and load priorities.

02

Islands & communities

Solar, storage and dispatchable generation assessed alongside local distribution and operator capacity.

03

Industrial clusters

Coordinated energy resources around production loads, power quality and operational continuity.

02 / Energy in motion

Operate as a coordinated local network.

The controller manages local resources and the exchange with the utility, within the site’s electrical limits and connection rules. Demand forecasts and resource availability inform dispatch.

03 / The engineering decisions

Engineer the network, not only the generation.

The first decisions establish resilience goals, electrical boundaries and who will operate the system.

A microgrid’s resilience comes from its complete operating design. Adding solar and batteries alone does not establish safe islanding or black-start capability.

01

Resilience & load priorities

Define essential services, outage scenarios, allowable interruptions and how non-essential demand will be managed.

02

Resource & network studies

Assess solar, storage, existing generators, distribution assets and the aggregated load profile.

03

Control & protection

Review voltage and frequency control, fault protection, communications and switching in connected and islanded modes.

04

Operations & cybersecurity

Plan operator responsibilities, secure control access, maintenance, spares and recovery procedures.

04 / From assessment to operation

Engineering that carries through.

A clear path from the first site inputs to a system your team can operate.

01

Set the system boundary

Stakeholder needs, critical loads, existing assets and the point of utility connection.

02

Study the architecture

Resource mix, distribution, storage, control and protection assessed together.

03

Integrate & demonstrate

Controller interfaces and the agreed switching, islanding and restoration scenarios tested.

04

Plan long-term operation

Operating procedures, secure monitoring and maintenance responsibilities established.

Before you begin

The questions that matter.

A useful system proposal starts with the right information.

01

How is a microgrid different from off-grid solar?

Off-grid solar describes a standalone supply. A microgrid describes a coordinated local network with a defined electrical boundary, potentially multiple sources and loads, and system-level control. It can be off grid or connected to a utility.

02

Can existing generators be integrated?

Potentially. Generator controls, ratings, protection and communications need review. Their dispatch strategy must coordinate with storage, solar and the loads in each intended operating mode.

03

Does a microgrid guarantee uninterrupted power?

No universal guarantee applies. Continuity depends on generation and storage availability, transfer behaviour, load priorities and the outage scenario specified. Critical no-break loads may need additional equipment.

04

What is needed before a feasibility study?

A site and network plan, consumption and critical-load data, existing resource details, utility connection information, resilience objectives and an understanding of ownership and operating responsibilities.
