DC photovoltaic switchboard, 1000V surge arrester, T1 T2, IP65
Additional set of solar connectors
⭐⭐⭐⭐⭐
➡️Doktorvolt photovoltaic switchboard:
✔️ is fitted with high-quality current protection components,
✔️ a surge arrester from a recognised brand, characterised by high performance and protection class T1 T2, is used for DC surge protection,
✔️ the switchboard has an IP65 protection rating, ensuring it is hermetically sealed and watertight,
➡️ Doktorvolt® has implemented a TÜV SÜD-certified management system for its switchgear manufacturing process:
✔️ a guarantee of high quality,
✔️ a transparent flow of information,
✔️ a guarantee of safety,
✔️ excellent customer service is guaranteed.

PLEASE NOTE! A very common cause of fires in PV installations is the use of solar connectors from different manufacturers. Connectors from different sources have different specifications – a poor fit leads to the generation of resistance, resulting in a rise in temperature which may cause the installation to catch fire. In Europe, the IEC 62548 and IEC 60364-7-712:2017 standards do not permit the connection of DC connectors from different manufacturers. The use of connectors and components from manufacturers other than those factory-recommended by Doktorvolt® is not permitted. To prevent accidents and ensure the safety of our customers, we include a set of solar connectors (2x female and 4x male) with the distribution board.
➡️Doktorvolt specialises in the manufacture of high-quality construction distribution boards with sockets, photovoltaic distribution boards and extension leads. The company stands out on the market for its quality, attention to detail and comprehensive customer service. Doktorvolt products are manufactured using tried-and-tested components sourced from European suppliers.
