In the past few years, due to large demands for solar energy, the photovoltaic industry has seen increased development in China. However, increase has been slower than expected after booming at the very beginning. After the '5.31 new policy' has been enforced, urgency turns to alleviating the decreased demands, thus enterprises should focus on obtaining technology breakthroughs or find other ways to reduce costs.
Solar Array Simulation Power Supply - IT6000C/B + SAS1000
Photovoltaic inverter is a special inverter that is designed for photovoltaic power generation. Given that the utility rate of solar cells is not only affected by it's natural features, but also influenced by climate, seasons, temperature, sunshine, cloud shadow, rain, snow and so on. It will show a different I-V curve at different times. Therefore, a PV inverter must have a solution to deal with all these situations whilst keeping the solar cells working under at maximum power. The efficiency of the PV inverter is the key factor to whole PV generation system, as it decides the long term profit of the system. Based on this, the simulator needs to simulate the output of different kinds of solar cells, simulate I-V curves in different temperatures and sunshine, generate new climate report flexibly and show irradiance changes with high resolution and speed.

Features
- Supported by SAS1000, it is responsive, controllable, repeatable, stable and precise.
- With the built-in EN50530 and Sandia SAS template, it is simple and convenient to set the parameters, such as regulations compliance, materials, Vmp and Pmp, etc. Then the I-V curve can be generated.
- Table mode enables you to choose 4096 points of curves or save 100 I-V curves generated under different temperatures and sunshine. The operation order and time of each curve can be set too.
- Shadow mode enables you to edit any shadow I-V curves and get the dynamic shield effect.
Applications
Battery simulator - IT6000B/C
Thanks to solar power and other distributed power, grid power is not the only power source anymore. However, when the load is small, we need an energy storage device to save the power collected by solar panels. We need to save the energy and prepare a back up for rush hours of energy consumption. There are many ways to store energy, e.g. physical energy storage, chemical energy storage, mechanical energy storage etc. The most common way is to store energy in a battery. Since it is not flexible or reliable enough to use real batteries to test, engineers rely on battery simulators. IT6000B is a high power, high power density DC power supply integrated with source and load functions. It can simulate the charging and discharging of batteries efficiently and smartly. Meanwhile, it can feed energy back to the grid with an efficiency of up to 95%, which reduces energy consumption. Above all, it is a highly efficient, energy saving and environmental friendly battery simulator.
- Design and verify MPPT of PV inverter
