Technical FAQs 4

Can an old inverter be turned into an emergency power system?

In this project, we would be modifing an old inverter into an Emergency Power System by constructing an automatic on/off switching circuit for the inverter.

How do I connect 230V AC to a home inverter?

The 230V AC output from the inverter is now available through the N/C contact. Fig. 4 shows a connection of the on/off switching circuit to the main inverter circuit. If the inverter output load is known, this simple circuit can be inserted in any home inverter for auto-on/off switching.

How does an inverter AC work?

The connected appliances are instantly diverted from the inverter AC to the mains AC within a split second such that the appliances doesn't even blink, giving an impression that nothing had happened and the are kept operative continuously without any interruptions. A comprehensive version of the above can be witnessed below:

How does a 12V regulated inverter work?

The 12V regulated output is fed to a 12V change-over relay through which the switching action takes place. When the 230V AC mains is available, the relay energises and its common pole shifts to the normally-open (N/O) contact. The 230V AC output from the inverter is not available at its output socket.
