«Example of connecting two or more inverters»
You can connect up to six inverters to one power regeneration common converter. The capacity of the power
regeneration common converter should always be greater than the sum of the connected inverter capacities or
the sum of rated inverter currents.
zWhen connecting several inverters, pay attention to the selection of the cables sizes since junction terminals or
jumper cables are used to wire the terminals P, N of the inverters. Make selection so that the inverter
capacities are added in order, starting with the one of the remotest inverter.
zWhen connecting several inverters, connect the inverters in order of larger capacities.

4) Connection of power supply and power regeneration common converter (power supply phase detection
terminals)
Note: 1. Correctly connect the terminals P/L+, N/L- with the inverter terminals P, N.
Wrong connection will damage the power regeneration common converter.
2. Do not insert the NFB between terminals P - N (P/L+ - P/+, N/L- - N/-, P/+ - P/+, N/- - N/-).

First inverter: Choose 38mm assuming
that the converter capacity
is 22K according to the sum
of inverter capacities,
11K+5.5K+3.7K=20.2K.
Second inverter: Choose 14mm assuming
that the converter capacity is
11K according to the sum of
inverter capacities,
5.5K+3.7K=9.2K.
Third inverter: Choose 3.5mm according to
the inverter capacity, 3.7K.
