Battery Connection - IMEON ENERGY 3.6 Guía De Montaje

Use earth ground cables. Remove insulation and connect it at the location marked with "
Ensure the earth ground wire is properly connected before turning on the IMEON inverter.

3.6 Battery connection

WARNING: It is very important for system safety and efficient operation to use appropriate
cables and to install the system in a correctly ventilated area. Thereis a risk related to the
voltage and current of the battery. It is necessary to cover the battery terminals.
Note: You can use lead acid or lithium batteries. Use lead acid batteries corresponding to IMEON
specification. Use only Lithium batteries approved by IMEON (see website).
Note: Lithium batteries installed in parallel on the same installation must be of the same model.
Note: Please check maximum discharge current 200A. The maximum charging current is 160A. In

current must be between 10% and 20% of the total battery bank capacity. The cable losses
between the battery and the inverter have to be integrated via IMEON OS. ONE. In order to

define the battery bank capacity necessary, a plant design has to be done at first.

Note: To preserve and optimize the lead acid battery life time, it is necessary to set the voltage
thresholds (see information supplied by your battery manufacturer).
Note: In case of Lithium battery, charge and discharge currents are dynamically imposed by the
battery‟s BMS. It is necessary to ensure that the consumption on AC BACKUP does not
exceed the discharge current of the battery, otherwise the inverter will go into error when the
grid is unavailable.
Note: In the case of a Lithium battery, at the request of the Battery Management System, a charge of
the battery by the network can be done in order to secure the battery (balancing charge).
WARNING: Before connecting to the batteries, please install DC circuit breaker and fuses
between inverter and batteries according to the existing standards.
Step 1: Make sure the nominal voltage of the battery corresponds to the technical specifications of the
inverter.
Step 2: Check polarity of the battery bank and identify the positive "+"and the negative "-" terminals.
WARNING: Incorrect polarity of the battery bank will damage the inverter! Check the system
before connecting the batteries.
Step 3: Switch the breaker and fuses to OFF position, in order to avoid electric arcs and the risk of
damage.
