20.1 PARALLEL INVERTER MODE - CONFIGURATION
1.The inverters must be interconnected using the cable supplied, making sure to populate the inputs as follows:
•
Link port 0
of
Master
inverter → connected to
terminating resistor
(8-pin terminal)
•
Link port 1
of

of
Slave n
Inverter
•
Link port 1
of
Slave n
inverter → connected to
terminating resistor
(8-pin terminal)
Note: The terminating resistors are supplied as standard
NOTE: the inverter parallel cable supplied is 3 meters long and cannot be extended.
2.If the inverters connected are of the same size, the LOAD outputs can be connected in parallel in order to supply
power to the same group of priority loads. To do this, a parallel switchboard must be used. It is necessary to
ensure that the connections between each inverter and the parallel switchboard have:
•
the same length
•
the same cross-section
•
the lowest possible impedance.
It is advisable to install suitable protection on each connection line between the inverter and the switchboard.
3.The total load connected to the LOAD outputs must be less than the total sum of the power outputs of the
inverters in EPS mode.
4.The meters must be connected to the Master Inverter (Primary)
The terminating resistors (supplied) must be
connected to the first and last inverters
