Option SI performance 3-phased

Three SI inverters can be connected together to build a 3-phased grid. They have to be equipped with the PE option.

Working

Two ways of working are possible with the SI performance :

1) Working alone

One SI inverter can be used alone. The inverter works then as a single one, like it is described in this manual.

2) Working in a grid

Thanks to the connecting cable, three inverters can be connected together in order to obtain a 3*400V 3-phased grid.

Connecting

1)Check that the inverters are in OFF position.

2)First link together the neutral of all 3 devices by taking care that this connecting point be not further than 1 m from each inverter.

3)Link together the battery cables (take care to not reverse the polarity). The 3 inverters have to be connected together to only one battery bank.

Commissioning

At the time of commissioning it is necessary to operate all the 3 inverters. The inverters work independently from each other and can be loaded in an asymmetrical way. They can work either in stand-by mode or in ON mode (see working description in this manual.
