The CTS5000 series is an integrated automotive-grade DC-AC inverter that converts vehicle battery DC into clean 110V/220VAC. With full isolation, anti-vibration design, and bottom cooling for IP67 sealing, it powers onboard AC appliances in trucks, RVs, construction equipment, and marine vessels.

The CTS5000 takes DC power directly from the vehicle battery pack and produces a pure sine-wave AC output suitable for sensitive onboard electronics, power tools, kitchen appliances, and marine AC loads. A full isolation barrier separates the DC input from the AC output, protecting both the vehicle low-voltage system and connected equipment.
Built with full-digital soft-switching control, the module maintains high efficiency and low THD across the load curve. The automotive-grade mechanical design withstands continuous vibration, dust, and moisture, while bottom cooling enables a sealed IP67 assembly for under-chassis or battery-box mounting.
The unit supports single-phase output by default and can be paralleled for three-phase or higher-power configurations. Bootloader-based firmware updates and backend debugging let OEMs tune output voltage, frequency, and protection thresholds per vehicle program.

Every mechanical and electrical choice is driven by the reality of on-road, off-road, and marine duty cycles.
Automotive Modular Design
Board-level integrated construction with automotive-grade PCB layout, optimized for under-hood and chassis-mounted EV environments.
Digital Soft-Switching Control
Full-digital soft-switching power stage delivers high efficiency, low EMI, and stable pure sine output across the load range.
Full DC/AC Isolation
Galvanic isolation between DC input and AC output protects vehicle batteries and connected AC equipment from ground faults.
Anti-Vibration Rated
Mechanical design meets automotive vibration and shock specifications, suitable for trucks, construction equipment, and marine applications.
Bottom Cooling & IP67
Direct bottom-plate cooling enables a fully sealed IP67 integrated assembly, eliminating exposed fans and moving parts.
Parallel & Bootloader Ready
Supports single-phase or three-phase paralleling, plus Bootloader-based firmware updates and backend parameter tuning.
Pick the input voltage matching your battery pack, and the output voltage (110VAC or 220VAC) matching your regional AC standard. All models share the same 200×140×50mm mechanical footprint.
