TESTIMONIALS

WHAT OUR CLIENTS SAY

“Their off grid pure sine power inverter compiance with (UL458)on first try. The dual China-Thailand production let us scale from 500 to 5,000 units/month without quality dips. More than a vendor – a power partner.”
Jack Wilson-CEO Energy Solutions 26 March, 2025
“Ordered 8,000 custom 3000W inverters with our branding and 50°C thermal specs. Sinemax’s Thailand factory delivered zero defects while cutting lead times by 40%. Finally, an Asian supplier that understands ‘rush’ means yesterday!”

Brian Murdoch– Supply Chain Director 11 December, 2024
”Initially, concerns existed about Chinese factories' communication efficiency, but Sinemax's team addressed them with English - fluent engineers and daily production photos. When the first batch of 2,000 12V 3000W inverters arrived, three had scratched casings. They swiftly air - freighted replacements within 72 hours - faster than our local suppliers.“ Richard Smith-Outback Mining Tech 09May, 2025
