The inverter PCB is easy to assemble by following the label of the components to be inserted. The choice of the voltage to be used to power the inverter ranging from 12v to 48v depends on kva you are designing. for any setup, a 12v relay is to be use.
The featuring M.C.U are the Microchip PIC16F72A OR PIC16F876A FEATURES OF THE ABOVE SCHEMATIC ARE STATED BELOW :
INVERTER PROTECTION : LOW-BATTERY SHUTDOWN
: OVER LOAD SHUTDOWN INPUT
: O/P SHORT CCT SHUT-DOWN INPUT
: HIGH TEMPERATURE SHUT-DOWN INPUT
: LOW-BATTERY : BEEP START AT 11 V
:INVERTER SHUT DOWN AT 10.5 V
:10 SEC DELAY BEFORE CHARGING
: AUTOMATIC VOLTAGE REGULATOR [INPUT: 180 V – 240 V] [OUTPUT: 211 V – 232 V]
INVERTER MONITOR : 16*2 LCD DISPLAY
