About 3cubeTech

We are a Freetown-based, full-service electrical and smart home technology company. We integrate three core offerings: smart automation, solar backup, and ongoing retainer support – because your property deserves one team that handles everything.

Why Sierra Leone Needs 3cubeTech

Unstable grid power and voltage fluctuations damage ordinary electronics. 3cubeTech solves that with surge protection, voltage regulation, and solar backup – then layers on smart automation to give you control, security, and energy savings.

We are not just a product reseller. We are an electronics-engineering led service company. Every smart switch, sensor, or inverter we supply can be installed by our trained electricians, and we stay on call to keep your systems working year after year.

Our Operational Promise

3cubeTech stocks critical spares in Freetown. We never keep you waiting for a replacement Shelly relay or a Tuya hub shipped from China. Our vans carry common parts, meters, and safety gear.
