Acrel Photovoltaic System Solutions
General
Solar PV has become one of the most popular new energy recent years. Therefore, a whole solution for power generation monitoring and reflux monitoring to each parts of Solar PV power distribution system become necessary for both distributed and centralized Solar PV.
Application 1. Distributed photovoltaic solutions
Nowadays, grid companies usually require photovoltaic grid-connected systems to be irreversible, that is, the electricity generated by photovoltaic grid-connected systems is consumed by local loads, and excess electricity is not allowed to supply to the grid. The system can regulate power generation in order to prevent the photovoltaic grid-connected system from generating reverse power.
Structure
• Solution for PV anti-backflow
• Solution for PV DC-coupled energy storage
• Solution for photovoltaic AC coupled energy storage
Main Functions
• Measure power generation and the use of electricity
• Data refresh rate: 250ms
• Split-core CT, 300A current
• Communication: RS485 and grid-connected inverter or energy storage inverter
Application 2. Centralized PV solutions
In the solar PV power generation system, the smart PV combiner box reduces the connection between the solar PV cell array and the inverter. The box can monitor the operating status of the solar panels, lightning protector and DC circuit breaker. With RS485 interface, the device can upload the measured and collected data and equipment status.
