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 or volt amps. They are
identical only when current and voltage are in phase then the power factor is 1.0. The
power in an ac circuit is very seldom equal to the direct product of the volts and amperes.
In order to find the power of a single phase ac circuit the product of volts and amperes
must be multiplied by the power factor.
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.
Safety

The Growatt MIN TL-XH US series inverter converts the DC current generated by the
photovoltaic (PV) modules to grid-compliant alternating current and performs single-
phase feed-in into the electricity grid. this series inverter is 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.
This grid-tied inverter system operates only when properly connected to the AC
distribution network. Before connecting the TL-XH US to the power distribution grid,
contact the local power distribution grid company. This connection must be made only by
qualified technical personnel to connect, and only after receiving appropriate approvals,
as required by the local authority having jurisdiction.
The GROWATT TL-XH-US Inverters is designed and tested according to international
safety requirements
（
UL1741
）
; however, certain safety precautions must be observed
when installing and operating this inverter. Read and follow all instructions, cautions and
warnings in this installation manual. If questions arise, please contact Growatt's
technical services at +1 (818)800-9455.

Danger to life due to lethal voltages!
Lethal voltages are present within the unit and on the power supply lines.
Therefore, only authorized electricians may install and open the unit.
Evenunit. Even when the unit is disconnected, high contact voltages may
still be present within the unit
Danger of burn injuries due to hot enclosure parts!
During operation, the four sides of the enclosure lid and the heat
sinkheat sink may become hot.
Onlyhot. Only touch the front enclosure lid during operation.
