Engineering Standards & Architecture
At Varnix Technology Co., Ltd., pure sine wave inversion relies on high-speed SPWM (Sinusoidal Pulse Width Modulation) microprocessor control. This guarantees distortion levels below 3%, matching utility grid wave cleanliness and preventing premature winding burnout in motors, compressors, and telecommunication hardware.
Smart LCD Diagnostics
Digital instrumentation provides real-time telemetry of DC battery voltage, AC output voltage, output frequency, continuous load percentage, and active fault codes (over-temp, short-circuit, over-voltage).
6-Point Hardware Protection
Equipped with galvanic isolation between DC inputs and AC outputs, reverse polarity protection, low-voltage battery shutdown, over-temperature protection, and automated short-circuit recovery.
OEM/ODM Engineering
Full design customization including customer brand logo, custom AC sockets (US, EU, UK, AU, Universal), modified DC terminal blocks, custom communication bus protocols (RS485/CAN), and private-label packaging.
Verified Manufacturing & Quality Control Floor
Every pure sine wave inverter is produced in our 1,229 m² SGS-verified manufacturing plant in Guangdong. Below are authentic photographs of our live production lines, automated testing benches, and quality assurance stations.

Frequently Asked Questions for Sourcing Managers
Can Varnix customize input voltage ranges and AC sockets for regional requirements?
Yes. Varnix Technology Co., Ltd. manufactures custom DC voltage solutions from 12V, 24V, 36V, 48V, 60V, 72V to 110V DC, and outputs for 100V, 110V, 120V, 220V, 230V, and 240V AC (50Hz or 60Hz). Sockets can be specified for North American (NEMA), European (Schuko), British (BS1363), Australian (AS/NZS 3112), or Universal configurations.
What is your typical production lead time and minimum order quantity (MOQ)?
Standard catalog units can be ordered in quantities as small as 1 to 10 units for sample verification and initial validation. Volume OEM production runs generally have a lead time of 12 to 20 working days. Rapid delivery of popular converter models is also supported via our US overseas stock.
How does Varnix guarantee true pure sine wave output?
Every inverter unit is tested via high-precision digital oscilloscopes during the 5-stage QC process to verify waveform purity. We guarantee Total Harmonic Distortion (THD) under 3% under linear loads, ensuring compatibility with inductive motors, variable speed pumps, and sensitive communications hardware.
What international certifications and audit reports are available?
Our pure sine wave inverters are fully certified with CE (EMC & LVD directives), RoHS environmental compliance, and FCC certifications. Furthermore, Varnix Technology Co., Ltd. is verified onsite by SGS Group, and comprehensive test reports can be furnished upon request with each shipment.
