Typically different voltage classes need a minimum separation since a failure of the insulation could send high voltage down low voltage lines. Australian/New Zealand codes require 50mm minimum separation (and that applies to conduit as well) and inside a cabinet there must be a barrier (e.g. a dividing insulator) between the two sides.
What to do if the solar high voltage distribution cabinet has no power the realisation that if mains goes high the output will go very high. A "safer" alternativ is a UPS or inverter run

In case of energy storage failure of high-voltage switch cabinet, the high-voltage light opening cabinet cannot be closed, the power supply is not normally distributed, and the factory The low-voltage power distribution cabinet is mainly composed of an incoming line cabinet, an outlet cabinet, a capacitor cabinet, a metering cabinet, and
So our system generates fewer watts because the voltage is lower. I expect it''s about 2-4% loss of generation. EDIT: Enphase triggers load-shedding protection on high voltage and should shut off completely at 255v unless reconfigured by an installer. I would expect a lot of solar would be dead if it was that hot during production hours.

The PV voltage needs to be a minimum of 120V to start up, and also 80V to continue operation. Causes of zero or low PV voltage: Not enough solar irradiance into the solar panels: Night. Cloud cover or bad weather. Shading – see this shading blog story for more information. Dirty panels. Seasonal differences. Wrong orientation and/or inclination.
If the PV array power rating is less than the solar charger nominal power rating, the solar charger cannot output more power than the connected solar array can provide. When the solar charger heats up, eventually the output current will derate. When the current is reduced naturally the output power will reduce as well.
The solar charger stops charging if the PV voltage exceeds the maximum rated PV voltage. At the same time, it will display an overvoltage error #33, and will fast blink its absorption and float LED. Charging will not recommence until the PV voltage has dropped 5V below the rated maximum voltage.
The PV voltage should never exceed the maximum rated PV voltage of the solar charger. The maximum PV voltage rating is printed on the front or on the side of the housing of the controller, and in the product specification sheets. The solar charger stops charging if the PV voltage exceeds the maximum rated PV voltage.
In case the PV array is located in cold climates or if the night temperature drops close to or below 10°C the PV array can output more than its rated Voc. As a rule of thumb, keep an additional 10% safety margin. An overvoltage event can damage the solar charger, depending on how much the maximum PV voltage was exceeded.
The charger will become faulty. PV panel isolation resistance too low. Check the PV array cabling and panel isolation, the inverter restarts automatically once the issue is resolved. The ground leakage current in the PV array exceeds the allowed 30mA limit. Check the PV array cabling and panel isolation.
