CAUTION: A very common cause of fires in PV installations is the use of solar connectors from different manufacturers. Connectors from different sources have different parameters – poor matching leads to the generation of resistance, the consequence of which is an increase in temperature that can lead to an installation fire. In Europe, IEC 62548 and IEC 60364-7-712:2017 do not allow the connection of DC connectors from different manufacturers. The use of connectors and components from other companies than those recommended by Doktorvolt® at the factory is not permitted. To prevent accidents and for the safety of our customers, we include a set of solar connectors M F 4 (4x female and 4x male) with the switching devices.
