High-Surge Power with Dual Remote Control

Take full command of your power supply. This model combines heavy output with ultimate user control. The oversized, crystal-clear LCD screen keeps you completely informed by displaying real-time input/output voltage, load power, frequency, battery status, and safety protection codes. For maximum flexibility, the 30-foot wired remote lets you manage power from inside your RV cabin, while the wireless remote provides instant backup control from a distance. Built-in UL-listed 20-amp GFCI outlets provide premium ground fault shock protection wherever you go.

 Customizable Battery Settings

Designed to adapt seamlessly to your DIY power configuration, this inverter features advanced battery compatibility. It fully supports 12V LiFePO4 (Lithium), lead-acid, ternary lithium, and other matching battery types. To protect your battery bank from over-discharge, you can custom-adjust the low-voltage protection threshold from 9.5V to 11.5V through the simple interface, tailoring the system to your precise power preferences.

 Heavy-Duty Construction & Advanced Safety

Built for life on the road or in the wilderness. Our inverter features a rugged aluminum alloy housing that accelerates heat dissipation while defending the core from bumps and drops during travel. For a high-output 4000W system, safety is non-negotiable—that's why we include fully insulated ring terminal cables, providing a far more secure and safer connection than risky, plastic-covered alligator clips.

The system also includes a comprehensive multi-protection suite guarding against undervoltage, overvoltage, overtemperature, overloading, and short circuits.
