1.4 System introduction
The whole system can be divided into hardware and software two parts. Photovoltaic off-grid system consist of photovoltaic components, controller/inverter, mains supply (city electricity network). Photovoltaic off-grid system structure is as follows:
Hardware part contains three independent photovoltaic power generation system, off-grid inverter, power box, meter box, hanging load box, etc., three photovoltaic panels connect in parallel, connect to off-grid inverter via hotovoltaic (pv) interface,measure system parameters.
1. Solar panel with aluminum bracket, the bottom is equipped with universal wheel, is flexible mobile and can be locked, solar elevation angle is adjustable.
2. Off-grid inverter is fixed in the training workbench desktop, through the cable connection and convert electricity from solar panels to power frequency 220 v alternating current (AC), for the use of the load.
Software part is composed of PC software and data communication cable, PC monitoring software can real-time monitor the working state of the photovoltaic off-grid inverter system, the input voltage, output voltage, battery voltage, load rate, battery capacity, the output work power, such as real-time data.
