Hi everyone,

I need a heater circuit for inverter so that when the inverter is turn off
heater starts and maintain the temperature of air above 20 deg celcius.

Kindly help me out thanks
 

Instead always swicthing on the heater when the inveter is off, you may consider to design it in a precise way, so that you switch a heater coil, through a relay, when the temperature in the Inverter cabinet decreases below a certain point. This can be easily done with a comparator IC like LM324 or LM358 or so.
Cheers
 

Seems like a simple relay (SPDT, coil off inverter main
switched power) and resistor (via NC contacts to inverter
unswitched power feed).
