Safety Measure; Symbols Introduction On The Inverter - Growatt SPH TL BL-UP Series Installation Manual

2.2 Safety Measure

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 470nF. 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 50mA due to the fact that the inverter would otherwise
automatically disconnect from the electricity grid as a protective measure.
Risk of high voltage！
·Relevant operation for professional personnel.
·Please notice children, disabled, laypeople do not close
·Supervise and make sure children don't play near the
installation position of energy storage machine
