Power Factor
Power factor is the ratio of real power and apparent power.
PV
Abbreviation for photovoltaic
wireless communication
The external wireless communication technology is a radio technology that allows the inverter
and other communication products to communicate with each other. The external wireless
communication does not require line of sight between the devices and it is selective purchasing.
2.Safety
2.1 Intended Use
The unit converts the DC current generated by the photovoltaic (PV) modules to grid-compliant
alternating current and performs three-phase feed-in into the electricity Grid.
PH5000-T series inverters are built according to all required safety rules. Nevertheless, improper
use may cause lethal hazards for the operator or third parties, or may result in damage to the
units and other property.
Principle of a PV plant with this PH50-XXXXT three-phase inverter
Fig1.1
The inverter may only be operated with a permanent connection to the public power grid.
The inverter is not intended for mobile use. Any other or additional use is not considered the
intended use. The manufacturer/supplier is not liable for damage caused by such unintended
use. Damage caused by such unintended use is at the sole risk of the operator.
PV modules Capacitive Discharge Currents
PV modules with large capacities relative to earth, such as thin-film PV modules with cells on
a metallic substrate, may only be used if their coupling capacity does not exceed 2.2uF.
During feed-in operation, a leakage current flows from the cells to earth, the size of which
depends on the manner in which the PV modules are installed (e.g. foil on metal roof ) and on
the weather (rain, snow). This "normal" leakage current may not exceed 100mA due to the
fact that the inverter would otherwise automatically disconnect from the electricity grid as a
protective measure.
