In this paper,we design a portable tester based on the volt ampere characteristic of MSP430. The power supply of the electronic device is a lithium battery, and the central control chip is MSP430, which has the characteristics of strong practicability,good compatibility, high cost performance and portability, both for large-scale photovoltaic field also applies to household photovoltaic power supply of solar array. According to the principle of capacitor charging and discharging, the portable tester is designed to test the hardware circuit and application software. Taking full account of the actual needs of the geographical environment, the good performance, easy to use, high accuracy, high speed and good real-time solar cell tester is designed.
