About Define

Define Engineering (known on its website as DEFINE) is based in Cheras, Kuala Lumpur, and is primarily an integrated engineering and security systems company, providing CCTV, access control, alarm and other ELV (extra-low voltage) systems, with additional offices in Vietnam and Singapore. It has since added a Solar Energy Solutions division serving residential, commercial and industrial clients across Malaysia, per its website.

The company's solar product listing includes a combiner box, KUKA solar PV cable, a CHINT DTSU666 smart meter, and a product listed as 'XG40KTR-S', though its website doesn't describe an installation process or publish any completed solar projects. Its core security systems business lists client industries including telecommunications, manufacturing, shopping complexes and government, without naming specific projects.

Enquiries for both its security and solar offerings go through its Kuala Lumpur office by phone or email. The website doesn't mention battery storage, EV chargers, maintenance plans, or financing options for its solar division specifically.

• Define Engineering's core business is security systems (CCTV, access control, alarms); ask about its specific track record and experience in solar installations before proceeding, since none are described on its website.
• No panel or inverter brand or warranty terms are published for its solar division — ask for these in writing.
• Confirm which of its offices (Malaysia, Vietnam, Singapore) would handle your project and after-sales support.
• Confirm the application is under Solar ATAP, which replaced NEM 3.0 on 1 January 2026.
