WARNING
CAUTION
Make all electrical connections (e.g. conductor termination,
fuses, PE connection, etc.) in accordance with prevailing
regulations. When working with the inverter powered on, adhere
to all prevailing safety regulations to minimize risk of accidents.
Systems with inverters typically require additional control (e.g.,
switches,disconnects) or protective devices (e.g., fusing circuit
breakers) depending upon the prevailing safety rules.
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 generated as follows:
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 generated 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.
House grid:
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 .
Public grid:
2.6. Operation Warnings
WARNING
Symbol description
Ensure all covers and doors are closed and secure during operation.
Although designed to meet all safety requirements, some parts and
surfaces of Inverter are still hot during operation. To reduce the risk
of injury, do not touch the heat sink at the back of the PV-Inverter or
nearby surfaces while Inverter is operating.
Incorrect sizing of the PV plant may result in voltages being present
which could destroy the inverter. The inverter display will read the
error message“PV Voltage High!”
Turn the rotary switch of the DC Disconnect to the Off position
immediately.
Contact installer.
CAUTION
All operations regarding transport, installation and start-up,
including maintenance must be operated by qualified, trained
personnel and in compliance with all prevailing codes and
regulations.
Anytime the inverter has been disconnected from the power
network, use extreme caution as some components can retain
charge sufficient to create a shock hazard; to minimize
occurrence of such conditions, comply with all corresponding
safety symbols and markings present on the unit and in this
manual.
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.
