Do you mean if you can connect a consumer in Delta connection? What type of device or motor do you want to connect? Do you have a foto of the nameplate of the motor?

Hi @Alexis Kalogerakis, no that is not possible. From the manual:


4.4.4 Three-phase operation

The Phoenix Inverter can also be used in 3-phase wye (Y) configuration. To this end, a connection between the devices is made by means of standard RJ45 UTP cables (the same as for parallel operation). The system (Inverters plus an optional control panel) will require subsequently configuration (see Section 5).

Pre-requisites: see Section 4.4.3.

Note: the Phoenix Inverter is not suitable for 3-phase delta (Δ) configuration.

Dag Matthijs, and in case of a 230V Delta network on board of a sailing yacht? Do we have any options?

Dag Piet, Yes we could do this with two units in serial connection and the 120deg splitphase settings. Then a third virtual phase is created which makes the system 3 x 230Vac. Or transformers inline creating 3p+n from 3p can be used.
