➡️ Solar junction box Doktorvolt\u00ae, advantages:<\/p>\n

✔️ it is designed for the protection of crystalline modules on the DC side,<\/p>\n

✔️ it is equipped with high quality components in the field of current protection,<\/p>\n

✔️ for DC -overvoltage protection, two surge arresters are used, which are characterized by high performance and protection class T2,<\/p>\n

✔️ IP65 protection class, so that junction box is hermetic and waterproof.<\/p>\n

➡️ In the production of the power distributors, Doktorvolt\u00ae has implemented management system certified by T\u00dcV S\u00dcD:<\/p>\n

✔️ Guarantee of high quality,<\/p>\n

✔️ clear flow of information,<\/p>\n

✔️ guarantee of safety,<\/p>\n

✔️ good customer service.<\/p>\n

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\u00ae 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.<\/p>\n<\/div>
