2.1 Safety Instructions
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. Even when the unit is disconnected, high contact voltages may still be present within the unit.
DANGER
DANGER
Danger of burn injuries due to hot enclosure parts!
During operation, the four sides of the enclosure lid and the heat sink may become hot. Only touch the front enclosure lid during operation.
CAUTION
Possible damage to health as a result of the effects of
radiation!
In special cases, there may still be interference for the specified application area despite maintaining standardized emission limit values (e.g. when sensitive equipment is located at the setup location or when the setup location is near radio or television receivers).In this case, the operator is obliged to take proper action to rectify the situation. Do not stay closer than 20 cm to the inverter for any length of time.
NOTICE
Grounding the PV generator
Comply with the local requirements for grounding the PV modules and the PV generator. Growatt recommends connecting the generator frame and other electrically conductive surfaces in a manner which ensures continuous conduction with ground these in order to have optimal protection of the system and personnel.

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
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.
NOTICE

Certified countries
With the appropriate settings, the unit will comply with the requirements specified in the following standards and directives
UL 1741
IEEE 1547
CSA C22.2 No.107.1-1
FCC Part15
Growatt can preset special grid parameters for other countries installation locations according to customer requests after evaluation by Growatt. You can make later modifications yourself by changing software parameters with respective communication products (e.g. shinebus or shineNet ect). To change the grid-relevant parameters, you need a personal access code, if you need it ,please contact with Growatt
DC and AC Switch
Separate the Growatt -US securely from the grid and the PV generators using DC and AC Switch. DC and AC Switch shall be able to disconnect all unground conductors after installation.
Grounding the PV modules
The Growatt-US is a transformerless inverter. That is why it has no galvanic separation. Do not ground the DC circuits of the PV modules connected to the Growatt -US. Only ground the mounting frame of the PV modules. If you connect grounded PV modules to the Growatt -US, the error message "PV ISO Low".
Approprite Usage
The Growatt Inverter converts DC Current from PV generator into AC current. The inverter is suitable for mounting indoors and outdoors. You can use the AC current gernerated as follows:
House grid:
Public grid:
Energy flows into the house grid. The consumers connected, for example, household devices or lighting, consume the energy. The energy left over is fed into the public grid. When the Growatt is not gernerating any energy, e.g., at night, the consumers which are connected are supplied by the public grid.The Growatt does not have its own energy meter. When energy is fed into the public grid, the energy meter spins backwards.
Energy is fed directly into the public grid. The Growatt is connected to a separate energy meter. The energy produced is compensated at a rate depending on the electric power company.

This unit or system is provided with fixed trip limits and shall not be
aggregated above 30 kW on a single Point of Common Connection.
PV Panel: Provide DC power to inverter.
Converts DC (Direct Current) power from PV panel to AC (Alternating
Current) power. Because Inverter is grid-connected, it controls the current
amplitude according to the PV Panel power supply. Inverter always tries to convert
the maximum power from your PV panel.
Connection system: This“interface” between Utility and PV-Inverter may
consist of electrical breaker, fuse and connecting terminals. To comply with local
safety standards and codes, the connection system should be designed and
implemented by a qualified technician.

Under any condition! Make sure the maximum open circuit voltage (Voc)
of each PV string is less than 450Vdc for Growatt1500-US,500Vdc for
Growatt2000-US&Growatt3000-US.
Wiring step:
Do not connect strings with an open circuit voltage greater than the Max. input voltage of the inverter. If the strings voltage exceeds the Max. input voltage of the inverter, it can be destroyed due to overvoltage. All warranty claims become void.
Check the design of the PV plant. The Max. open circuit voltage, which can occur at solar panels ambient temperature of -10 , must not exceed the Max. input voltage of the inverter. Before connecting PV panels to DC terminals, please make sure the polarity is correct. Incorrect polarity connection could permanently damage the unit. Check short-circuit current of the PV string. The total short-circuit current of the PV string should be less than the inverter's maximum DC current. Connect the positive and negative terminals from the PV panel to positive (+) terminals and negative (-) terminals on the Inverter. Each DC terminal on Inverter can withstand 12Adc for 1500-US,14Adc for 2000-US, 17Adc for 3000-US. High voltages exist when the PV panel is exposed to the sun. To reduce risk of electric shock, avoid touching live components and treat connection terminals carefully

Glossary
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). The energy is the power calculated over time. If, for example, your inverter operates at a constant power of 20,000 W for half an hour and then at a constant power of
10,000 W for another half an hour, it has fed 15 000Wh of energy into the power distribution grid within that hour.
,
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 or volt amps. They are identical only when current and voltage are in phase than 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 photovoltaics.

Operation Modes12 Operation Modes12
12.1 Normal Mode
In this mode, the inverter works normally and LED turns green.
1.
Whenever
the DC voltage is higher than 150Vdc, inverter converts power to grid
as generated by the PV panels;
2.
Whenever
the DC voltage is lower than 150Vdc, the inverter will work in waiting
state and attempt to connect the grid. In waiting state the inverter consumes just
enough power generated by the PV panel to monitor the internal system status;
NOTICE
The inverter starts up automatically when the DC power from
the PV panel is sufficient.
12.2 Fault Mode
The internal intelligent controller can continuously monitor and adjust the system
status. If inverter finds any unexpected conditions such as system fault and inverter
fault, the fault information will be displayed on the LCD. In fault mode the LED turns
red.
NOTICE
Detailed fault information refers to 13. Trouble shooting.
12.3Shutdown Mode
Inverters automatically stop running during periods of little or no sunlight. In
shutdown mode the inverters take no power from the grid and panel, and the LCD
and LED turns off.
NOTICE
If the PV string DC voltage is too low, the inverter will also
turn to Shutdown Mode.
De-rating Operation 13De-rating Operation 13
Temperature
The inverter will monitor the temperature of the heat-sink. Once the temperature
exceeds 75°C (167°F) ,the system will reduce the output power until the temperature
drops under the critical value. The inverter will shut down the power output to the
grid if the temperature reaches 85°C (185°F). If this occasion happens often, it is
necessary to check whether the inverter is mounted at an appropriate place with
good ventilation and not directly exposure to the sunshine.
