I have my Mahindra powerol inverter 1000VA making continuous beep and all led glow except battery indicator on inverter panel . should I change the PIC16F72 or any resistor ?
if you unplug everything from the output side of the UPS, the "overload" will (presumably) go out
that should give the UPS a chance to charge the battery
and (presumably) the beeping will stop
i think the beeping is related to the overload and/or the low battery
is the input side connected to the appropriate power source?
if there is an input voltage switch, is it set to the correct supply voltage?
(i blew up an HP ARB, yes, it was HP in those days, not Agilent, by plugging it into a 220V Source, with the switch set to 110V)
as noted before, what does the owner's manual say about the beeping and the LEDs?
what does the owners manual say about the first charging, when you take it out of the box to use it?
how old is it?
how old is the battery?
did you follow all of the steps to set up the UPS?
