Sabah Electricity's Banggi Island station is a solar-battery-diesel hybrid supplying homes, schools, and businesses on the island. Current owner documentation gives 1,200 kWp of PV, a 720-cell gel battery bank, and eight diesel generators ranging from 200 kW to 1,000 kW against an approximately 950 kW served load. A Leonics engineering presentation for the project records a 1,200 kWp array, 2,075 kW of inverter capacity, a 2,880 kWh main battery bank, and 1,650 kVA of diesel capacity. The station has received battery, inverter, and diesel upgrades and remains in service, but no source found provides a current annual renewable-energy percentage.

Research status
Operating under Sabah Electricity as of the owner's current ESG account reviewed in July 2026. That account says battery and inverter upgrades and added diesel capacity have sustained performance. Commissioning dates conflict by phase/source: TNB describes commissioning in 2013, while Leonics records commercial operation on 25 January 2014 and operation since February 2014.

Project delivery

Who was involved in Banggi Island Microgrid?

4 publicly identified organizations. Where a recovered source named a participant without explaining its work, the role remains explicitly unspecified.

Organization

Leonics

Supplier of bidirectional battery inverters, PV grid inverters, MPPT equipment, and hybrid control equipment documented for the 1.2 MWp project. [6][7]

Organization

Sabah Electricity Sdn Bhd (SESB)

Owner and operator of the Banggi solar-hybrid station and the island distribution service. [5]

Organization

Tenaga Nasional Berhad (TNB)

Parent utility of SESB and publisher of the current operating account. [5]

Organization

Usaha Sirimas Sdn Bhd

Main contractor identified in Leonics' project record. [6]

System evidence

Energy mix, capacity, and specifications

Values can describe different project phases, generation sources, storage systems, or other components. Source citations are attached to each figure so discrepancies remain visible.

KW Solar
1200 [1]
KW Gas/Diesel
1350 [1]
Storage
4300 kWh [1]
Solar PV capacity
1,200 kWp [5][6]
Leonics project battery rating
2,880 kWh main bank; the engineering diagram also shows a 720 kWh remote-bank value, which should not be silently added without phase clarification [6][7]
Current owner battery description
720 gel cells; a current energy capacity is not disclosed [5]
Leonics inverter capacity
2,075 kW total: 1,100 kW battery-side and 975 kW PV/grid-side in the vendor project table [6]
Leonics diesel capacity
1,650 kVA in the project summary; individual-generator values vary between vendor diagrams and appear to reflect configuration or phase changes [6][7]
Current diesel fleet
Eight generators, each rated between 200 kW and 1,000 kW; aggregate current capacity is not stated [5]
Served load
Approximately 950 kW serving homes, schools, and businesses [5]
Energy mix
Solar generation with battery storage and diesel backup/supplement; no verified annual percentage split was located [5]

Controls and hardware

Equipment and controller details

Manufacturer and model are shown only when a source names them. Generic descriptions are not converted into guessed product assignments.

01

Bidirectional battery inverters

Leonics

The engineering diagram identifies three 300 kW bidirectional inverter blocks (900 kW shown at this level), within a project table that reports 1,100 kW of battery-inverter capacity. [6][7]

02

PV grid inverters

Leonics

Three 250 kW PV grid-inverter blocks (750 kW) are shown in the main-station diagram. [6][7]

03

PV charge control

Leonics

Three 70 kW MPPT blocks (210 kW total) are shown for DC-coupled PV, alongside three 75 kW remote grid-inverter blocks (225 kW). [6]

04

Hybrid control

Leonics

Hybrid Control and Communication Unit (HCCU) coordinating PV, batteries, and diesel generation. [6][7]

Technical record

Architecture, performance, and project updates

Concise technical facts, milestones, operating results, and later developments. Dated notes distinguish historical design claims from current evidence.

  • General

    Sample application of PV – Wind Turbine- Diesel Generator Hybrid Minigrid System [1]

  • Architecture

    The vendor diagrams show a mixed AC/DC-coupled hybrid: PV grid inverters feed the AC bus, MPPT units charge a 480 VDC battery system, bidirectional inverters form/support the island grid, and diesel generators provide backup and firm capacity. [6][7]

  • Commissioning record

    TNB's current account says the plant was commissioned in 2013. Leonics' project documentation instead gives 25 January 2014 as COD and describes operation since February 2014; these may reflect construction, handover, or phased commercial-operation milestones. [5][6][7]

  • Later upgrades

    The current owner says battery and inverter upgrades have sustained performance and additional diesel capacity has been installed for high demand. It does not identify the replacement vendors, models, dates, or energy capacity. [5]

  • Rating caveat

    A Leonics slide labels 4.93 MW by arithmetically summing PV nameplate, inverter capacity, and diesel capacity. That figure is not a valid independent generating-capacity rating and is not used here as plant output. [6]
