Product Description

Distributed power access unit protocol converter

1.Product profile
In recent years, with the continuous integration of distributed photovoltaic systems on residential rooftops, the randomness, intermittency, and decentralization of distributed photovoltaic systems have posed challenges to power grid dispatch and management. To ensure the safe and stable operation of the power grid and accurately grasp the data of photovoltaic power generation, we have launched the "Four Possible" product solution. Power grid dispatch can analyze users' electricity load situation through big data, adjust the output capacity of photovoltaic inverters, and enhance the on-site consumption capacity of new energy.
This product is developed using modern digital communication technology, computer software and hardware technology, low-voltage power line carrier technology, etc. The downlink communicates with the inverter through RS485 serial port, and the uplink supports carrier dual-mode communication to upload data to the dispatch platform, achieving the "four capabilities" function for distributed new energy equipment.
This product has excellent electromagnetic compatibility performance, a wide temperature adaptability range, and a wide voltage adaptability range. The converter housing is made of ABS flame-retardant material, with a rail type structural design, which is lightweight, easy to install, supports multiple types of interfaces, and is compatible with multiple protocols. It has been tested by a third-party authoritative organization.
The four meanings are observable, measurable, adjustable, and controllable.
1) Observable: Achieve the acquisition of voltage, current, power, and power generation data for low-voltage user photovoltaic power plants;
2) Measurable: Integrating high-frequency collected data, such as user profiles and external meteorological data, to construct user power generation prediction and abnormal operation analysis
Analysis and violation of electricity monitoring model;
3) Adjustable: When distributed photovoltaics affect the power quality and safe use of electricity in the substation area, it can adjust the AC active output of the photovoltaic inverter
Perform flexible control;
4) Controllable: When photovoltaic power generation threatens the safe operation of the power grid, the main station can remotely disconnect to ensure the stability of the power grid.
