Solomon Islands Power Plugs, Wall Sockets & Electrical Outlets
In Solomon Islands, power plugs and sockets (electrical outlets) of Type G (BS 1363, three rectangular pins in triangular pattern, grounded) and Type I (AS/NZS 3112, two angled flat pins plus vertical grounding pin, grounded) are used. Wall sockets run at 230V and 50Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to Solomon Islands.

Power Sockets and Plug Types in Solomon Islands
Solomon Islands power plug standards reflect the country's history of British and Australasian influence, meaning travelers may encounter two different types of AC power plugs and sockets depending on the building or region they are visiting. The electrical supply runs at 230V and 50Hz, matching the standard used across most of the South Pacific and former British territories. Both Type G and Type I plugs and sockets can be found in use, so it is worth checking your accommodation in advance or packing an adapter that covers both configurations.
Type G, the British BS 1363 standard, features three rectangular pins in a triangular pattern and is commonly found in properties built with UK-influenced wiring systems. Type I, the Australasian AS/NZS 3112 standard, uses two angled flat pins plus a vertical grounding pin and is also widely installed, reflecting regional trade and infrastructure ties with Australia and New Zealand. Each socket-outlet is designed to accept only its corresponding plug type, so having the correct adapter is essential for a secure connection.
Grounding and the Earth Pin
Both plug types used in Solomon Islands are grounded designs, providing an added layer of protection for appliances and users. The Type G plug places its earth pin at the top of the triangular arrangement, where it opens the socket's internal shutters and connects before the live and neutral pins. The Type I plug's vertical grounding pin serves the same protective function, ensuring that any fault current has a safe path to earth rather than through the user.
Where to Buy a Travel Adapter for Solomon Islands
Universal travel adapters that include both Type G and Type I configurations are widely available at airport shops, electronics retailers, and online marketplaces before you depart. Buying one before your trip is generally easier than sourcing one locally, since availability in Solomon Islands itself can be limited outside major towns. Look for an adapter rated for at least 10-13A and 230V to safely match the electrical standards used on the islands.
What Plug Type Does Solomon Islands Use?
Solomon Islands uses both Type G and Type I plugs, so the correct adapter depends on the specific socket-outlet installed at your destination. Type G, familiar from the UK and many former British territories, is rated for 13A and includes a built-in fuse for individual appliance protection. Type I, the Australasian standard also used in Australia, New Zealand, and other Pacific nations, is rated for 10A and features distinctive angled pins.
- Type G (BS 1363): three rectangular pins, 13A, includes internal fuse
- Type I (AS/NZS 3112): two angled flat pins plus vertical grounding pin, 10A
- Voltage: 230V, Frequency: 50Hz
Frequently Asked Questions
Yes, unless your home country already uses Type G or Type I plugs, you will need a travel adapter to fit Solomon Islands' sockets. Since both plug types are found in use, a universal or dual-standard adapter is the most practical choice.
Solomon Islands uses both Type G (BS 1363), with three rectangular pins in a triangular pattern, and Type I (AS/NZS 3112), with two angled flat pins plus a vertical grounding pin. Which type you encounter depends on the building's electrical installation.
Solomon Islands operates on a 230V supply at 50Hz, consistent with the standard used throughout most of the Pacific region and former British and Australasian territories. Travelers from 220-240V countries can typically use their appliances without a voltage converter.
Yes, both Type G and Type I sockets used in Solomon Islands are grounded designs. Type G includes an earth pin that connects first and disconnects last, while Type I incorporates a vertical grounding pin, both providing protection against electrical faults.
