AC - distribution and protection

AC Photovoltaic installations require different protection than ordinary residential installations
„

• Overcurrent protection must be determined according to the respective load of the solar inverter on the AC side

„

• Distribution boards in PV installations must not be dimensioned simply according to the number of consumers (as is the case with ordinary residential installations, where simultaneity factor is low), but you need to take into account wider cable cross-sections, higher rated currents etc.

„

• High power dissipation, as a result of constant high loads, is typical for PV installations and needs to be reducedbelow the maximum operating temperature of individual devices (larger enclosures, setting devices furtherapart to allow air circulation etc).

We provide design, engineering and consulting services and production of custom made AC PV junction boxes. You can choose between busbar system and mounting plate system.
