Description

Panel for protection against transient overvoltage in photovoltaic systems.

Photovoltaic installations are used to transform solar radiation into electrical energy, which can be self-consumed or injectedinto the power grid.
The ECO-DC-INV-AC also maintains the same number of inputs as outputs with the exception of the 2+2, for the new multi-MPP inverters, and the individual 1000Vdc fuse holder and Vdc surge protector protections. The inputs are via MC4connectors.
We also protect the AC part with a Type A differential protection, a circuit breakerand a Vac Type II transient overvoltage protection with its
associated protection
The protectors that incorporate the ECO-DC-INV-AC have been developed to protect against discharges and surges produced by lightning impacts in the continuous part of these systems. The protection consists of three stages of varistors equipped with thermal switches that indicate through a window the failure of the element. It has a remote output (indication contact).
