It supports function verification, metrological testing and performance evaluation, and is compatible with both simulated and physical photovoltaic inverter connections. It also enables the simulation of various types of distributed generation equipment.
Functiongs
- The communication ports of the units under test at each meter position of the verification device are independent and parallel, supporting multiple communication methods including Bluetooth, RS-485, Ethernet, CAN, Modbus, etc.
- It supports DL/T 698.45 protocol testing.
- Automatic judgment and data rounding processing are available for test results.
- The device comes with proprietary verification software, and also provides middleware to support verification with the official verification software issued by the power grid.
- The device adopts an integrated structure.
- Both voltage and current of the device can be independently adjusted up and down, featuring fully automatic range switching and automatic load matching.
- The device is equipped with comprehensive fault detection, protection and alarm functions. It is fitted with an emergency stop switch, along with voltage and current circuit protection, which can effectively prevent device damage caused by human operation errors.
