Overview
The NXP® Solar Panel Inverter reference design demonstrates the ability of the 16-bit digital signal controller MC56F8023 to control whole inverter functionality.
- The inverter converts the input voltage from the solar panel to isolated one-phase AC output voltage
- The application comprises all needed circuitry for power transfer, control and measurement
- The main power board provides standard 64-pin PCI Express® connector as the interface for the daughter card control board, providing the ability to control this inverter by other digital signal controllers
Features
- DC input voltage from the solar panel in the nominal level of 36V
- Possible to use one 36V or two 18V solar panels in series connection
- Maximum power point tracking feature in the control software implemented
- Battery charger for the 3 x 12V lead-acid accumulators in series included
- Galvanic isolated output voltage 230V 50Hz up to 400W output power
- True sine shape output voltage
- RS-485 isolated interface for the external communication
- Internal low-power DC power supply maintains proper functionality without battery connection
- Overvoltage, overcurrent and overtemperature protection implemented
- Embedded software example for off-grid available
