Use micro-inverter to optimize solar system




Solar system for optimizing the efficiency and reliability is concerned, a relatively new means of connecting to each solar panel with micro-inverter (micro-inverter). For each block, with a separate mini-solar panel power inverter allows the system to adapt to changing load and weather conditions, allowing for the single-block panels and provide the best conversion efficiency of the entire system.

Micro-inverter structure can simplify cabling, which means lower installation costs. By making consumers more efficient solar power system, the system "recall" the original use of solar energy technology will shorten the time required for investment.

Power inverter is the key to solar power generation system of electronic components. In commercial applications, these components are connected photovoltaic (PV) panels, storage batteries and local electric power distribution system or utility power grid. Figure 1 shows a typical solar inverter, it is the output from the PV array into low DC voltage battery DC voltage, AC line voltage and voltage distribution network several kinds of voltage.

In a typical solar energy collection system, a number of solar panels in parallel to an inverter, the inverter will come from the variable number of photovoltaic cells convert the DC output of clean sine wave inverters 50Hz or 60Hz.

In addition, it should be noted that in Figure 1, the microcontroller (MCU) module TMS320C2000 or MSP430 typically contain, such as pulse width modulation (PWM) module and A / D converter on-chip peripherals such key.
