Upgraded Pure Sine Wave: The 3000W Pure Sine Wave Inverter converts 12V DC battery power into stable AC 110V/120V 60Hz household electricity. It provides 3000W continuous power and 6000W peak surge power, featuring 1 DC 5V 2.1A USB-A port, 1 DC 18W USB-C port, and AC outlets. Pure sine wave output (THD <5%) ensures clean and stable power for sensitive electronics. LCD Display & Remote Controller: The integrated LCD display indicates input voltage, output voltage, load power, output frequency, battery level, and error codes, enabling real-time monitoring of system performance. An optional remote control panel with RJ12 port and 6m cable allows convenient operation from a distance, suitable for RV or truck installations. Advanced Multi-Protection: Engineered with 10 built-in 35A fuses, the inverter offers comprehensive protection including overload protection, over-temperature protection, short-circuit protection, over-voltage protection, and under-voltage protection. Temperature-controlled cooling fans automatically activate above 65°C to maintain stable operation. High-Power Direct Connection Terminal: Unlike standard inverters that rely only on outlets, the DSU3000 includes a heavy-duty 110V direct-connect terminal, permitting direct wiring for high-load applications. This design supports stable power delivery under heavy electrical demand, suitable for RV systems, off-grid solar setups, large appliances, and high-power equipment that require reliable and continuous energy. Package. Versatile Application Compatibility: This 12V to 120V inverter is designed for use in RVs, trucks, boats, off-grid solar power systems, and emergency home backup situations where reliable AC power conversion from DC battery sources is required
