Vocational Physics Experiment Solar System Educational Teaching Board Kits

Brief introduction

To help students understand the principles of solar photo voltaic and learn the engineering application of solar photo voltaic. This system is a solar photo voltaic power system that can provide a practical teaching, testing and demonstration platform for solar cells, sine wave inverter and controller. The work flow will be: 

1.The solar energy is converted to low voltage 12VDC by solar cell module.

2.Then charge the battery through the controller. 

3.Then convert 12VDC into 220VAC for all the load by sine wave inverter.
