(2PCS) Luminous NXG 1500va OLD Microcontroller IC

​Key Microcontroller Details ​Part Reference: Often identified in spare part markets as the "1500_1A" Microcontroller IC. ​Package Type: Usually a 28-pin DIP (Dual In-line Package), which makes it easier to replace if it fails compared to modern SMD (Surface Mount) versions. ​Function: It acts as the "brain" of the unit, controlling the PWM (Pulse Width Modulation) for the sine wave, managing the solar-to-grid changeover, and protecting against overloads or short circuits
