48VDC-380VAC 20KW Low Frequency Inverter from China Suppliers | Factory Direct Pure Sine Wave Solution

Rated DC input voltage of 48V, supporting an ultra-wide voltage range (e.g., 42V–100V or customised range), capable of adapting to extremely low voltage scenarios as low as 42V, ensuring stable output even under battery under-voltage conditions.

Rated output power 20kW, output voltage 380VAC (three-phase), frequency adjustable 50Hz/60Hz, pure sine wave output (THD ≤3% for linear loads), dynamic response time ≤50ms, power factor ≥0.99, efficiency ≥88%.

Utilises a line-frequency isolation transformer to achieve complete AC/DC isolation, effectively suppressing harmonic interference and enhancing system surge resistance. Supports inductive loads such as motors and water pumps (e.g., automatic recovery after 10 seconds at 115% overload).

Through wide voltage input design (e.g., 42V–100V) and intelligent boost technology, it ensures full power output even during deep battery discharge or fluctuating PV input, preventing shutdowns caused by insufficient voltage.

Shielded enclosure and optimised grounding, certified to CE (EMC/LVD) standards, meeting industrial-grade anti-interference requirements.

Reduces switching noise and suppresses harmonic distortion to ensure pristine output waveforms.

Input over/under-voltage, output overload/short-circuit, overtemperature, fan failure, and lightning protection. Supports RS485/CAN communication interfaces for remote monitoring.

Utilises IPM smart modules (e.g., Mitsubishi 6th generation IPM) and power frequency topology, supporting operation across -25°C to 50°C with altitudes ≤3000m (derating required). Service life extends to 15 years. Modular design facilitates maintenance.
