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.
