ZA Tech Inc. is a technology company in Irvine, California, with two branches under one roof: renewable energy testing equipment, designed and built with HOTOTECH, and marketing and brand development through the True American brand.

Marketing

The True American brand.

True American is our consumer-facing brand: patriotic print-on-demand merchandise, apparel, accessories, and everyday goods, sold directly on this store. Choose your piece, add it to the cart, and check out on Shopify. There are no quote forms on this path. If you came to shop, you're in the right place.

Renewable energy testing

Designed and built with HOTOTECH.

ZA Tech with HOTOTECH designs and builds any test equipment, including custom. Labs and manufacturers use these field instruments and factory test systems to strengthen quality control and issue certificates backed by real test results. Battery and ESS products are quoted on a separate path.

This branch serves:

• Installers
• O&M
• EPCs
• Module manufacturers
• Testing labs
• Inspectors
• Government inspection labs
• UL / certification bodies
• Battery/ESS labs

Tell us the instrument or the test, and request a quote. Nothing in this branch goes into the shopping cart.

For the wider catalog, use lab-tester.com (opens in a new tab). That site is the HOTOTECH catalog. ZA Tech does not own it.

Visit us at RE+ 2026, Booth C5080, Central Hall, Las Vegas, November 17-19. There is no equipment in the booth.

We also support data center cooling projects on a limited basis. Mention data center cooling when you contact us.
