Pure Sine Wave Solar Inverter 12V/24V/48V/60V to 220V — 3000W & 4000W Voltage Transformer with Multiple Safety Protections

Durable aluminum-magnesium alloy housing: lightweight with excellent thermal conductivity to quickly dissipate heat from internal components so prolonged operation is unaffected. Equipped with an intelligent temperature control fan — the fan stops working when the temperature is 45 , and the fan starts working when the temperature is 45 . True pure sine wave output with an intelligent filter prevents interference and safeguards connected devices. High conversion efficiency (up to 95%) and low self-consumption help extend battery runtime. Compatible with a wide range of appliances including TV, LED lights, LCD displays, and inductive loads such as refrigerators, freezers, and induction cookers. Designed to match city mains quality with 110 / 220 support. The unit includes a buzzer reminder: if any protection is triggered the inverter will immediately disconnect output power, place the load into protection mode, and alert users with a 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. Intelligent chip control provides reliable protective management.
