2.2 Safety Precautions
The GROWATT UE series Inverters is designed and tested according to international
safety requirements; 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 +86 755 2747 1942.
2.3 Assembly Warnings
CAUTION
WARNING
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.
Prior to installation, inspect the unit to ensure absence of any
transport or handling damage, which could affect insulation
integrity or safety clearances; failure to do so could result in safety
hazards.
Unauthorized removal of necessary protections, improper use,
incorrect installation and operation may lead to serious safety,
shock hazards or equipment damage.
In order to minimize the potential of a shock hazard due to
hazardous voltages, cover the entire solar array with dark material
prior to connecting the array to any equipment.
Grounding the PV modules: 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 and ground these in order to have optimal
protection of the system and personnel.
2.4 Electrical Connection Warnings
DANGER
Some components in the inverter are live. Touching live components
can result in serious injury or death.
Danger to life due to high voltages in the inverter
All work on the inverter may be carried out by qualified
personnel only.
The appliance is not to be used by children or persons with
reduced physical, sensory or mental capabilities, or lack of
experience and knowledge, unless they have been given supervision
or instruction.
Children are forbidden to play around the Growatt inverter.
WARNING
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.
The Growatt UE series inverters may only be operated with PV
generators (modules and cabling) with protective insulation. Do not
connect any source other than PV modules to the Growatt UE series.
Systems with inverters typically require additional control (e.g.,
switches, disconnects) or protective devices (e.g., fuse, circuit
breaker) depending upon the prevailing safety rules.
CAUTION
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 UE series inverters do not generate any energy,
e.g., at night, the consumers which are connected are supplied
by the public grid. The energy displayed on the LCD of inverter
is for reference only. When energy is fed into the public grid,
the energy meter spins backwards.
Energy is fed directly into the public grid. The Growatt UE
series inverters need install a separate energy meter. The
energy produced is compensated at a rate depending on the
electric power company.
2.5 Operation Warnings
WARNING
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.
The Growatt inverter is to be used solely to feed solar energy
converted photovoltaically into the public grid. The inverter is
suitable for mounting indoors and outdoors.
You can use the AC current generated as follows:
