Micro Inverter

Micro Inverter

Customer Location: Switzerland, Europe

Requirements: The customer was looking to build a 600W micro inverter for solar panels that can be connected to the grid. Microinverters must be designed with panel and control system protection, whether connected in series or in parallel.


Designed Solar micro inverter with TI DSP microcontroller to generate pure AC signal from solar panel DC power. For inverters, we used a bipolar PWM switching mechanism. The inverter is protected against overvoltage, low solar input, short circuit, and isolation.

Electrobit is an expert in the development of a high-efficiency solar inverter and has offered the complete solution.
