Islands and remote communities share a power challenge: electricity has to be generated close to where it is used, fuel often arrives by sea or long road journeys, and the local grid is small enough that every load change is felt. Abundant sunshine changes the equation. A hybrid system that combines solar power, battery storage and generator sets delivers dependable 24-hour supply while reducing the fuel each kilowatt-hour requires. MPMC POWERTECH CORP. (MPMC), founded in 2008 and headquartered in Shanghai, manufactures every part of such a system, from small all-in-one storage units to containerised power stations, and has delivered island and off-grid power from Indonesia to Kenya and Chad.

Three Scales of Island and Remote Community Power

Homes, Clinics and Small Businesses

At the smallest scale, MPMC's HBD-E Series integrates inverter, PCS and EMS in one cabinet, from 10 kW / 30.7 kWh to 125 kW / 261.2 kWh, with PV input of up to 250 kWp. CE and CEC certified, with remote control by app or PC, these units suit homes, clinics, shops and hotels on islands and in field camps, and most models ship eight to ten units per 20-foot container.

Villages and Community Microgrids

For a village or a group of public buildings, MPMC's GSB hybrid power stations combine a 2,375 W slide-out solar array, LFP storage and a generator set in one mobile unit from 10 kVA to 120 kVA, while the GB Series, with optional solar MPPT input, covers outputs up to 500 kVA with up to 430.1 kWh of storage. SPK mobile solar plants from 7.65 kWp to 231.84 kWp add further generation as demand grows.

Island Power Stations

Island grids are built on containerised generator sets from 800 kVA to 3,750 kVA per single-engine unit, with two-engine units from 1,250 kVA to 3,000 kVA. Multiple sets in parallel provide N+X redundancy and independent black start, and HBD-A storage from 125 kW / 261 kWh to 1,125 kW / 2,170 kWh per unit acts as a power buffer in VSG and grid-forming modes. For extended island layouts, the MCLS2000H(S)-1 generates 2,000 kVA prime at 11,000 V for direct high-voltage distribution.

Growing the System in Stages

Because every building block is containerised and managed by the same EMS, a community can start with the capacity it needs today and add more as demand grows. A common path begins with generator sets and battery storage, which right-size the engines and cover evening peaks; solar arrays follow as land and funding allow, and DC-coupled HBD-DC 410 or HBD-DC 5000 storage suits large solar-plus-storage additions. Each new block joins the existing system under the same controls, so operators keep familiar procedures as the network expands.

How the Hybrid System Runs

Solar First, Storage Second, Generator Sets on Demand

MPMC's self-developed EMS uses multi-source data and weather forecasting to maximise PV generation, schedule battery charging and dispatch generator sets as demand requires. During the day, solar carries the load and charges the battery; in the evening, storage supplies the community; and generator sets run at efficient output to cover longer periods and recharge the battery. Switching between solar, storage and diesel is seamless.

Grid-Forming Storage for Small Grids

Small island grids benefit from storage that can lead as well as follow. MPMC systems support PQ and VF control, VSG mode that emulates inertia, black start, grid-forming operation and reactive power regulation, so the battery stabilises voltage and frequency and can re-establish the grid on its own.

Remote Operation With a Small Local Team

MPMC's SCADA platform provides real-time monitoring and control across all sites, alarm management, maintenance work orders and automated reports, with ten years of data retention under an SL3-level cybersecurity framework. Starlink satellite communication serves as a backup link, which keeps island and remote sites visible to engineers wherever they are. In Kenya, a four-site microgrid of this design delivers stable 24/7 power in a high-UV, sandy environment with minimal on-site staffing.

Renewable Fuel for Firm Capacity

Generator sets in a hybrid system can also run on renewable fuel. MPMC's 21.6 MW island power station in Indonesia runs entirely on biodiesel using Cummins KTA50-GS8 engines and Leroy-Somer LSA50.2 L8 alternators. A separate 18 MW project in Indonesia uses eighteen 1 MW containerised sets on B35 biodiesel, each rated 1,200 kW prime and 1,000 kW continuous, lowering lifecycle CO2 by up to 85% compared with petroleum diesel and complying with RED II and RFS standards. Natural gas and methanol generator sets widen the fuel choice further.

Engineered for Coastal and Tropical Sites

Island equipment works in salt air, humidity and heat. MPMC containers are protected to ISO 12944 C4 or C5 standards, sprayed products undergo 500 to 700 hours of salt spray testing twice a year, and generator sets are designed for 50°C ambient with copper radiators. The Kenya microgrid reports zero corrosion. Containerised formats ship efficiently by sea, with up to four GSB units per 20-foot container, and each generator set is load-tested from 0% to 110% before it leaves the factory.

Why Island Utilities and Community Developers Choose MPMC

MPMC supplies generator sets, battery storage, solar arrays and hybrid power stations from its own factories, all coordinated through one EMS and SCADA platform, so a utility or community developer can grow from a first village system to a full island station with a single supplier. MPMC is also the developer of China's national standards for mobile hybrid power stations, and every project includes design consultation, customisation, factory testing, logistics and commissioning support.
