FAQ

Which installations is it for?

Inverters with three MPPTs or several inverters, and roofs with three orientations or three panel groups. Each string is protected and can be disconnected on its own.

What does a PV protection box do?

It protects the DC line between the panels and the inverter: fuses isolate a shorted string or reverse current, the surge protector (SPD) diverts lightning surges to earth, and the DC breaker lets you disconnect the panels to work on the inverter safely.

What is the maximum string voltage?

Up to 600 V DC. Check the string's open-circuit voltage (Voc) at low temperature before installing — in winter it can exceed the nominal value by 10–15 %.

Where is it installed?

Wall-mounted near the inverter or on the roof. The enclosure is IP65, suitable for outdoors, with MC4 connectors for the strings and cable glands for the output and earth.

Does it need a qualified electrician?

Yes, it must be installed by a certified electrician under low-voltage regulations, with the SPD earth connected. Bilotex installs it together with the panels and inverter.
