Power
Power is measured in W (watts), kW (kilowatts) or MW (megawatts). Power is an
instantaneous value. It displays the power your inverter is currently feeding into the
power distribution grid.
Power rate
Power rate is the radio of current power feeding into the power distribution grid and
the maximum power of the inverter that can feed into the power distribution grid.
Power Factor
Power factor is the ratio of true power or watts to apparent power.
PV
Abbreviation for photovoltaic
Wireless communication accessories (optional)
The external wireless communication technology is a radio technology that allows
the inverter and other communication products to communicate with each other.

2.1 Intended Use
TL3-S series inverters are grid-tied inverters which convert DC current generated by
PV modules into AC current and feed it into the public grid in three-phase. TL3-S
series inverters are multi-string inverters with multi-MPP trackers, which mean they
are able to connect to different PV module arrays.
Grid-tied PV system Overview:
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 as intended use. The manufacturer/supplier is not responsible for any
damages resulting from unintended use. Damage caused by such unintended use is
at the sole risk of the operator.
As drawings shown above, a complete Grid-tied PV system consists of PV modules,
DC fuse or breaker (only for France, the other country is optional), PV inverters,
public grid and other components. Moreover, PV inverters always act as key
components.
When design a PV system contains any Growatt inverters, the system designing
software "ShineDesign" (download from site: www.ginverter.com) will provide
adequate supports.
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.
