Eco-Dc-2-Inv

Protection panel against transient overvoltages in photovoltaic systems. Photovoltaic installations are used to transform solar radiation into electrical energy, which can be self-consumed or injected into the grid.

Unlike the ECO-DC model, the ECO-DC-INV maintains the same number of inputs as string outputs, each of the strings are protected with 1000Vdc fuse holders and Vdc surge protectors.

On the other hand, the inputs are made with MC4 connectors (optional) for a faster and safer connection. This system is designed for inverters with multi-MPP management that incorporate different string inputs. The protectors that incorporate the ECO-DC-INV have been developed to protect against discharges and overvoltages produced by lightning strikes in the continuous part of said systems. The protection consists of three stages of varistors equipped with thermal disconnectors that indicate through a window the failure of the element. It has a remote output (indication contact).
