The control cabinet houses a blue\u2019Log park controller from meteocontrol, which is used for regulating and monitoring a photovoltaic system. The system is complemented by a power quality analyzer for monitoring current and voltage values, network components for communication, and an uninterruptible power supply (UPS) for maximum operational reliability.<\/p>\n<p data-start=\"1332\" data-end=\"1611\">The optimal internal temperature of the control cabinet is between <strong>5\u00b0C and 40\u00b0C<\/strong> \u2013 with ambient temperatures ranging from <strong>\u201320\u00b0C to +45\u00b0C<\/strong>.
