The configuration should be such that everything takes place automatically and the appliances are never switched OFF, just reverted from inverter AC to Mains AC and vice versa during mains power failures and restorations. So here I am with a couple of simple yet very efficient little relay. .
Looking at the diagram we can see that the unit requires two relays, however one of them is a DPDT relay while the other one is an ordinary. .
In the second concept below I have explained how to build a 10kva solar grid inverter changeover circuit which also includes a low battery protection feature. The idea was requested by Mr. Chandan Parashar. Circuit. .
I am looking for circuit comprising of the comparator (LM 324) to drive a relay. The objective of this circuit is to: 1. Sense AC supply and switch relay 'ON' when voltage is in between 180-250V. 2. Relay should turned 'ON' after 5. .
The 10kva solar/grid automatic inverter changeover circuit with low battery protection which is requested above can be built using the concept presented in the following figure: In. [pdf]
