4 FAQs about [Inverter plus AC contactor]

What is a power contactor?

A power contactor is an essential component in electrical systems, providing efficient control over power distribution in industrial, commercial, and even residential applications. By understanding the power contactor working principle, types, and specifications, you can select the right contactor for your needs.

How do I connect a contactor coil to a Multiplus-II?

Any standard contactor can be used. Since inverter current flows through the AC outputs of the MultiPlus-II units, ensure the external transfer contactor wiring is appropriately sized and symmetrical. Connect the contactor coil directly to the NO and COM terminals of the MultiPlus-II "AUX RELAY" terminals of the L1 phase master unit.

How do you wire a Multiplus-II inverter?

Since inverter current flows through the AC outputs of the MultiPlus-II units, ensure the external transfer contactor wiring is appropriately sized and symmetrical. Connect the contactor coil directly to the NO and COM terminals of the MultiPlus-II "AUX RELAY" terminals of the L1 phase master unit. Fuse this wire with a 2A fuse.

What are DC contactors used for?

These contactors support operations through AC voltage and find their use in HVAC systems, lighting control applications, and motor control centers. The applications needing direct current utilization employ DC contactors in battery chargers, solar inverters, and railway systems.
