2.1 Intended Use
Growatt TL3 series inverters are to be used solely to feed solar energy converted
photovoltaically into the public grid. Growatt TL3 series inverters are multi-string
inverters with multi-MPP trackers, which mean they are able to connect to different
PV module arrays.
Fig 1.1
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 as intended use. The manufacturer 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,
PV inverters, public grid and other components. Moreover, PV inverters always act as
key components.
When design a PV system contains Growatt TL3 series inverters or any other Growatt
inverters, the system designing software ShineDesign (download from site:
www.ginverter.com) will provide adequate supports.
AC
Abbreviation for "Alternating Current”
DC
Abbreviation for "Direct Current”
Energy
Energy is measured in Wh (watt hours), kWh (kilowatt hours) or MWh (megawatt
hours).
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.
