Inverter plus AC contactor

4 FAQs about Inverter plus AC contactor

What are the advantages of a contactor in a central inverter?

Now contactors are increasingly used, offering numerous advantages: since they can be operated remotely, automated switching operations can take place in the central inverter. Thus the string connections can be modified to increase the system's efficiency.

What is AC contactor?

An AC contactor is an electromechanical switching device designed to switch AC loads on/off. It is used for switching high-current AC loads. The working principle of the AC contactor involves electromagnetic force cooperating with the spring force to make and break the connection between the source and load.

What are the different types of AC contactors?

AC contactors are mostly available in 3-pole and 4-pole versions. You can choose between them depending on the load type and control circuit requirements. For instance, 3-pole AC contactors are usable in three-phase systems, while 4-pole AC contactors can be used in 3 phase 4 wire system or 1 phase 2 wire system. 4. Lifespan

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.
