Important Safety Warning
BEFORE BEGINNING: Read this guide carefully.
This manual will guide you during your installation and your check before starting the production.
CAUTION: This manual is for qualified staff having high skills and the necessary
experience in inverter installation as well as electricity. It is absolutely forbidden to
proceed to the mounting or dismounting of this kit if you do not have the necessary
skills.
CAUTION: Besides the electric risks on all the installation, the handling of batteries can be
dangerous. Never approach a spark of a battery recently charged. Gloves and safety
glasses are necessary to work near batteries for complete safety.
CAUTION: Authorized service staff should reduce the risk of electrical shock by
disconnecting AC, DC and battery power from the inverter before attempting any
maintenance or cleaning or working on any circuits connected to the inverter. Turning
off controls will not reduce this risk. Internal capacitors may remain charged for 5
minutes after disconnecting all sources of power.
CAUTION: Do not cover IMEON. It is fitted with a heat removal system to avoid any
overheating.
CAUTION: Do not disassemble IMEON yourself. It contains no user-serviceable parts.
Attempt to service IMEON yourself may cause a risk of electrical shock or fire and will
void the warranty from the manufacturer.
CAUTION: To avoid a risk of fire and electric shock, make sure that existing wiring is in
good condition and that the wire is not undersized.
The responsibility of the supplier could not be committed for damage caused by a bad maintenance or
by not respecting the instructions of this manual.

SMART GRID
Thanks to the intelligence of management and the multi energy real-time coupling of the IMEON, the
yield is maximized by choosing the mode of energy presenting the best cost/efficiency ratio: either by
consuming it (self consumption), or by injecting the produced electricity in the electric grid or both at
the same time. Automatic adaptation to the installation’s configuration without necessary parameter
setting, is one of its many smart features.
ECONOMIC
No need for solar charging regulator, for source’s switch or for additional inverters. Thanks to its
intelligent (SMART GRID) functions, IMEON allows to store energy only when it is necessary and, by
improving the efficiency, to lower the price of energy produced by more than 30%. The intelligence of
management and the real-time multi-energy coupling allow to decrease the capacity of the battery and
to improve its life expectancy (number of cycles reduces).

2- Overview of IMEON 3.6 inverter
2-1 Connections
IMEON is an inverter that is composed of a grid input, a solar panels output, a battery input/output and
an output for the 230 Vac production.
2-2 Compatibility
This intelligent hybrid inverter is designed to manage the continuous power of three different sources
of energy, the solar panels, the battery (with or without wind turbine), and the grid electricity, according
to various configurations.
The inverter uses the maximum power point technology (MPPT) to optimize the maximum quantity of
energy supplied by the solar panel. When the solar panels MPPT input is between 120Vdc and
510Vdc, this hybrid inverter can inject the power on the utility and charge battery. This inverter is only
compatible with PV module type of single crystalline and poly crystalline. When the PV input voltage is
lower than 250 Vdc, the deliverable power by the inverter will be reduced.
Some precautions must be realized to make sure that the maximum voltage of open circuit never
exceeds 510 volts. Please note that the maximum voltage will occur in the lowest temperature
planned. You will find detailed information about the influence of the temperature in the data sheet of
the PV module manufacturer.
2-3 Standard devices
The inverter contains the following standard devices:
4- Complete readable data thanks to the graphic design by LCD.
5- To prevent the electric risk, a current transformer is used to watch the difference of current
between L and N. When the difference is bigger than the indicated value in the section
"specification", the inverter will cut its grid (utility) injection.

3-4 PV Module (DC) Connection
CAUTION: Before connecting to PV modules, install separately a DC circuit breaker between
inverter and PV modules.
Put protections (circuit breakers, fuses and lightning conductors) according to existing standards.
Before the photovoltaic system is connected, the solar field’s tension must be verified to
make sure that it is correct.
Never open the inverter when the solar field is connected. Disconnect first this one if it’s necessary.
WARNING: Because this inverter is non-isolated, only two types of PV modules are acceptable:
single crystalline and poly crystalline with only Class A-rated. To avoid any malfunction, do not
connect any PV modules with possibility of leakage current to the inverter. For example, non-
grounded PV modules will cause leakage current to the inverter.
Step 1: Check the input voltage of PV array modules, which have to be included in the range of
functioning of IMEON.
CAUTION: Exceeding the maximum input voltage can destroy the unit!! Check the system
before wire connection.
Step 2: Disconnect the circuit breaker

3-7 AC Grid Connection
Before connecting to AC utility, please install a separate AC circuit breaker between inverter and AC
utility. This will ensure the inverter can be securely disconnected during maintenance and fully
protected from over current of AC input.
Note: Although this inverter is equipped with a fuse (30A), it is still necessary to install a separate
circuit breaker for safety consideration. Please use protections (circuit breakers,fuses and
lightnin conductors) according to existing standards.
WARNING: It is very important for system safety and efficient operation to use appropriate cable for
grid (utility) connection.

5- Commissioning
Verify the continuous Vdc voltage of the solar panels:
¾ Uncover the solar panels and expose them to the full sunlight. The sunlight must be rather
intense to produce the necessary voltage on the inverter.
¾ Measure the Vdc voltage on the open circuit of the solar panels through the positive
terminal C.C(-) and the negative terminal C.C(+). This voltage must be included between
120 V continuous and 510 V continuous to activate the electronics of the inverter.
Verify the Vac voltage :
¾ By using a voltmeter in Vac position, measure the voltage of the open circuit between L
(phase) and N (neutral). Assure that this output voltage is equal to the value of the grid.
Verify the battery voltage :
¾ Assure that the battery voltage is for the nominal value approximately planned for the inverter
(48 Vdc).
¾ Verify the good sizing of the cabling between the inverter and the battery.
CAUTION: Before switching on, verify again all the connectors and all the connectings.
