Pure Sine Wave Solar Inverter 3000W / 4000W — 12V / 24V / 48V / 60V to 220V Voltage Transformer, Fast & Efficient 12V 220 Inversor

Durable aluminum-magnesium alloy housing — lightweight with excellent thermal conductivity to rapidly dissipate heat from components, allowing continuous operation without performance loss. The unit includes an intelligent temperature-controlled fan: when the temperature is 45 the fan stops working; when the temperature is 45 the fan starts working. Pure sine wave output with an intelligent filter ensures clean power that won’t interfere with or damage sensitive devices. High conversion efficiency (up to 95%) and low self-consumption help extend battery life. Supports a wide range of appliances — TVs, LED lights, LCD displays and especially inductive loads such as refrigerators, freezers and induction cookers. Designed to deliver city-quality power at 110 / 220. Built-in buzzer reminder — if any protection is activated the inverter will immediately cut output, put the load into protection mode and sound the buzzer. Eight-bit intelligent protection: overload protection, high voltage protection, low voltage protection, overheating protection, reverse connection protection, short circuit protection, overcurrent protection, insurance protection. All protections are managed by an intelligent control chip for reliable safety.
