About Us

CalTech is a South African energy and technology company based in Randburg, Gauteng. We supply high-quality solar equipment and tech products to homes and businesses across the country — from Victron Energy inverters and charge controllers to laptops, monitors, and accessories.

As an authorised Victron Energy distributor, renewable energy is at the core of what we do. We help customers build reliable, high-performance solar systems with components they can trust — backed by accurate product information and real after-sales support.

Beyond solar, we carry a curated range of technology products selected for performance and durability, whether you're kitting out a home office or sourcing hardware for a business.

You'll find CalTech on all major South African e-commerce platforms, including Takealot and Amazon.

Every product we sell is sourced from authorised suppliers. We operate transparently, stand behind our listings, and are fully compliant with South African consumer protection laws.
