Mcu based inverter control with A.V.R using pic16f876a

Monitoring of an inverter during operation has being the major challenge faced by local inverter Manufacture which has lead to low demand for locally built Inverters due to sudden break down or Battery being overcharged. most of the Inverter schematic claimed or used by Local Inverter Manufacture downloaded from the internet are for tutorial purpose not not for commercial there are tendencies for failure therefore it is time for us to start developing things of our own...
proudly NIGERIA......
The featuring M.C.U is the Microchip 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
                                         : ERROR LED
                                         : BUZZER

    Thank you very much for this circuit, but the code is incomplete there are some errors in the code that disgracing the circle.
    1. You can not turn on or off ips when there MAIN SUPPLY
    2. In case ips in playback mode The MAIN SUPPLY exist
    When the outage will not be switching to the inverter only if it reaches the reading when I / Put VOLT This works to slow the switch
