6 FAQs about [Can a 12v AC contactor be connected to an inverter ]

Can multiple inverter/Chargers be connected in parallel?

Multiple inverter/chargers can be connected in parallel to create a larger inverter/charger. When connecting a parallel system to an AC supply it matters what length and thickness the AC wires have. Unlike DC cabling, for AC cabling it is important to not make the cables too short or too thick. Do not over-dimension the AC cabling.

How do I charge a battery from an inverter?

There is no problem as long as the Inverter stays off, but once the inverter is turned on, the AC-DC charger will try to charge the battery from the Inverter. I have seen the solution is to put a contractor (AC relay) between the AC Panel and AC-DC charger that is switched by power coming from the Inverter.

How to use E-stop contactor in an inverter?

First, if you put an E-stop contactor in the input leads of an inverter, from the time you open the contactor until the DC bus capacitors discharge, you will get normal motor at-speed operation. Following that you get coast-to-stop operation of the motor and coupled machine.

How do inverter Chargers work?

There are inverter chargers that have this functionality built in that would go between your incoming shore power and the AC panel. They automatically switch between shore and battery power, if shore is plugged in then it passes through the inverter to the panel and charges the battery automatically.

How to calculate fuses & wiring size & inverter size?

To be able to correctly calculate fuses, wiring size or inverter size, you will need to know how large the current in the AC circuit is. To be able to correctly calculate the current, there is one aspect of AC power that will need to be explained, namely Watt and VA. Like explained before, AC power is alternating power.

Can a Allen-Bradley drive be used with an output contactor?

"Allen-Bradley Drives can be used with an output contactor between the drive and motor. This contactor can be opened under load without damage to the drive. It is recommended, however, that the drive have a programmed “Enable” input and that this input be opened at the same time as the output contactor." Re 1. A contactor in front of the VFD:
