Connection possibilities

Inverter, charger and transfer relay

The Xtender basically works as an inverter and as a charger, combined with a transfer relay.

2 or 3 units in parallel on 1 phase

Increase of the power on one phase by setting 2 or 3 Xtenders in parallel.

1 phase In and 3-phase Out

Three-phase power supply from a single phase source.

3-phase In and 3-phase Out

Three-phase source for a three-phase power supply.

3-phase + with one reinforced phase

Three-phase power supply with increase of the power on one phase by setting 2 or 3 Xtenders in parallel on this phase.

3 Xtenders in parallel on 3 phases

Three-phase power supply with 3 Xtenders on each phase; for power up to 72kW.



The inverter/charger has a continuous power rating of 3.5kVA up to an ambient temperature of 40°C. In addition, it has a 30 minute power rating of 4kVA, and can deliver 10.5kVA for up to 5 secondsThanks to this very high surge power capacity, it can supply without worries loads with a high start-up current.

The battery charge current can be adjusted between 0 and 50Adc. The factory default settings include a battery charge curve best suited for lead acid batteries with gelled electrolyte (GEL). This battery charge curve can be easily adapted to other types of batteries including OPzSNiFeLithium and Redox Flow, to name but a few.
