Product Description

Features and Beneifits of PV Inverter EMI Filters:

• Prevention of the electromagnetic interference of inverter towards controller and solar panel. 
• Prevention of the electromagnetic interference of inverter towards other grid-tied equipments. 
• Effectively get rid of the electromagnetic pollution of inverter output current, guarantee the grid power quality. 
• Effectively eliminate the negative influence of radiated interference of solar panel towards inverter and controller. 
• Greatly improve system reliability and effectiveness. 
• 600VDC, 1200VDC or above high voltage versions available upon request. 
• Strict temperature rise control and much better performance than actually required assure product reliability even under special working conditions.

Typical Applications of Inverter Filters:

• PV inverters 
• High power frequency conversion device 
• Other electronic equipment comprising inverters

Technical Data of PV Inverter Filters:

1. Storage of EMI Filter for Inverter: 

•  The RFI filters mustn't be left out in the heat of the sun or exposed to the rain, it should be stored in warehouse with good ventilation, surrounding temperature between -30℃ and +65℃ , the highest relative air humidity lower than 90%, and no corrosive liquid or gas.

2. Installation of EMI Filters:  

• PV Inverter filters should be installed at power input, and the line inside the chassis be as short as possible to reduce radiated interference. 
• Both input and output lines of Inverter filters neither be intersected nor be tied up by string.
• Make sure the mounting flange fully grounded, and keep the ground cable as short as possible if filters are connected to other equipment. 
• If the terminal is stud, please use two spanners to fasten the screw nut when connecting to avoid stud rotating and thus causing changes to the internal circuit and consequently leading to filters arcing, short circuit, broken down or the filtering effect worsened. 
• First use spanner1 to fix the screw nut near the metal case, then use spanner2 to tighten the screw nut in front( shown as Figure1), otherwise the terminals may be damaged. 
• Apply the same for the connection of other phases.
