⚡ Function in the Electrical System

The FN2200B is installed between the photovoltaic field and the inverter to reduce high-frequency conducted emissions on the DC side and limit interference that could propagate toward the PV modules. The filter also helps protect the panels from HF leakage currents, which can contribute to premature aging of the modules.

🏭 Identification and Connections

The PV-FIELD, INVERTER, +, −, and PE indications are also visible, with a recommended tightening torque of 17–20 Nm.

🛡️ Safety and Product Condition

The component shows normal signs of use and installation, with light abrasions on the metal housing. Functionality is not declared without specific testing.
⚠️ 1200 VDC / 150 A: component for high-voltage, high-power photovoltaic circuits. Connection must be carried out exclusively by qualified personnel, respecting polarity, PV-FIELD/INVERTER direction, PE, and tightening torque. Dangerous DC voltages may be present even when the system appears to be switched off.
