Portable solar power generation test box is a solar photovoltaic power supply system, through it which can provide a practical teaching, testing, demonstration platform for solar cells, controllers and sine wave inverter work principle. Its work flow is firstly solar modules to convert solar energy into low-voltage DC power, and then through the controller to charge 12V battery, but also supply power on the back of the inverter, the inverter will make 12V DC into 220V AC, supply a variety of load use. Technical parameters: 1. Input power: 220V± 10% 50HZ 2. Equipment Size: 1 # box: long X wide X high = 590X490X200mm 2 # box: long X wide X high = 600X450X370mm 3. Working environment: temperature -10?? ~ 40?? 4. Relative humidity
