GreenMore customized microgrid solutions

A microgrid combines local generation, battery storage and controls so a site can run connected to the grid or independently. No two sites need the same thing: a villa values quiet operation and appearance, a hotel or office values stable supply, a mine or construction site values fuel savings, and a hospital or data center values uninterrupted power. GreenMore designs customized microgrid systems in small, medium and large configurations, matched to each site's loads, local grid and available solar resource.

How the Three Configurations Compare

Small Microgrid Systems

Small systems serve lower-power sites such as factory office areas, hotels, high-end villas and scenic-area facilities, often behind a single connection point.

• Three-phase unbalanced-load support. The converter uses dynamic power distribution so the phases can run with unequal loads. If one phase carries a heavy single-phase load, such as a large appliance or charger, the system keeps output stable instead of tripping on imbalance.
• Environmental adaptation. Temperature control, condensation management and filtered ventilation support operation in humid and dusty locations; the rated operating range should be confirmed against the specific model datasheet for the site climate.
• Modular expansion. Multiple units operate in parallel, so battery capacity or inverter capacity can be added as demand grows, for example when new loads or charging points are added.

For lighter loads, smaller storage units such as a 10 kWh energy storage unit can be combined to reach the required capacity without replacing the installed equipment.

Medium Microgrid Systems

Medium systems serve construction sites, mining operations, shopping malls and remote projects where grid supply is limited or unavailable. They coordinate solar, battery storage and a backup generator so each source is used in order of cost.

• High solar input. The power-conversion stage can accept a large photovoltaic array, with solar used first where it is available so the generator runs fewer hours. Supported PV capacity varies by model and is specified during design.
• Built-in protection. Multiple protection functions cover overload, short circuit, over/under-voltage and islanding, isolating a fault while power to the remaining loads continues.
• Containerized delivery. Systems can be supplied in a standard container for sea freight and lifted into place on site, which shortens civil works and commissioning for overseas projects compared with building a plant room from scratch.

Large Microgrid Systems

Large systems serve industrial parks, hospitals, data centers and other sites where continuity is critical and loads are concentrated.

• Fire detection and suppression. Gas-based suppression, temperature sensing and BMS alarms detect abnormal heat and allow a controlled response; exact detection and response functions depend on the configured system.
• Grid-forming PCS. The power-conversion system can behave like a synchronous generator, supporting voltage and frequency when multiple loads start together or when renewables vary, and can operate grid-tied or off-grid.
• High-integration, liquid-cooled design. Liquid cooling and compact internal layout raise power density and reduce the footprint of large systems, while also lowering ventilation requirements compared with air-cooled equivalents.

What GreenMore Customizes

Because there is no single standard microgrid, each project is engineered around the site rather than supplied as a fixed package:

• Technical configuration — capacity, power rating, duration, PV and generator sizing, and communication protocols are set to match the loads and local grid.
• Project support — solution design, installation and commissioning guidance, plus operation and maintenance training for local teams.
• Partner collaboration — GreenMore works with distributors, dealers and system integrators so projects have local technical response and after-sales support.

If you are planning a site that needs to run partly or fully independently, share the load profile, location and reliability requirement and GreenMore will propose a configuration sized for it. To start a project, contact the GreenMore team or email export@gmsolarkit.com.

Frequently Asked Questions

What is the difference between grid-tied and off-grid microgrids?

A grid-tied microgrid works with the utility grid and can export or import power; an off-grid microgrid operates independently and must balance its own generation, storage and load. Most GreenMore systems can also run in a hybrid mode, staying grid-connected normally and islanding during an outage.

Does a microgrid still need a diesel generator?

Not always. Solar plus a suitably sized battery can cover many sites, but a backup generator is often retained for long cloudy periods or extended outages. The hybrid controller uses solar and storage first and starts the generator only when needed, which reduces fuel use.

How is microgrid capacity chosen?

Capacity is based on the site's peak load, how long it must run independently, the available solar resource and required backup duration. A load profile or monthly consumption data is usually enough to begin a preliminary design.

Can an existing diesel-only site be converted to a hybrid microgrid?

In many cases yes. Solar, storage and a hybrid controller can be added alongside existing generators so they run less often and at a more efficient loading point. Compatibility with the existing equipment and switchgear is checked during the site assessment.
