How can convert 600VA ups to simple inverter


It already is an inverter. When on battery power it becomes an inverter.

UNINTERRUPTIBLE POWER SUPPLY


UPS – UNINTERRUPTIBLE POWER SUPPLY
Uninterruptible power supplies provide protection against mains power faults to computer equipment.
These faults include voltage spikes/interference, over voltage and under voltage, mains supply interruptions and surge protection etc.
These faults can cause computer and electronic equipment that are connected to an unprotected mains supply to malfunction and/or sometimes fail.
A common problem, when burning Cds, DVDs etc. any slight power interruptions to the burning process will halt the recording process and rendered the disc useless.

There two type of Uninterruptible Power Supplies
The lower powered and cheaper type UPS are switch-over types, when the mains supply fails, the UPS switches over to the batteries and inverter in milli-seconds which then supplies mains power to the computer and peripherals. A faulty inverter circuit and or flat batteries won’t deliver standby power when the mains supply fails.
NOTE : The mains waveform from these UPS is a pseudo sine wave (i.e. not a true sine wave).
The true UPS types are usually the higher KVA units (over 1500 VA) that supply continuous mains power. The mains power is connected to a charger which charges the batteries and then the inverter draws power from these batteries and converts it to true sine wave mains power to the computer equipment, therefore there is no switch over time lag when the mains supply fails.

UPS - Battery Fault


UNINTERRUPTABLE POWER SUPPLY
Batteries in the UPS typically last 3 to 5 years and it depends upon several factors. Including the number of times the unit must go on battery power and environmental conditions. There are usually several batteries in the UPS and while the battery voltage may show 13 volts, this may only be a float charge/voltage and a true indication of the battery voltage and condition requires the batteries to be tested under a load. If one battery is faulty in a set of batteries it will causes the whole battery system to fail and indicate a battery fault. A faulty charging circuit will not charge the batteries and will also cause a fault condition.

A faulty inverter circuit and or flat batteries won’t deliver standby power when the mains supply fails.

Can i have all the basic details of UPS system


UPS come in two types, lower powered cheaper types are usually switch over power.
These units senses a power outage and then switch over to the battery power to generate mains supply. The switch over occurs in milli-secs and does not affect the computer.
True UPS types constantly run off battery power to generate mains supply so there is no switch over time lag. These units are higher powered and higher costs units.

Both type of UPS have the same components.
Battery charger.
Batteries
Inverter that converts battery voltage to mains voltage
Electronic controls

When UPS is shut down the lights go out on front pannel but power remains on plugs. It is coming from the AC side not the battery.


The UPS has a fauly/problem.
If your UPS is approx. 600VA, then it is not a true UPS unit but a switch over type. When the mains power fails the UPS switches over to the battery and inverter in milli-secs to provide mains power.
If you turn off the mains supply and shut down your UPS, but you are still getting mains power, then there is a fault with the switch over circuit.
You need to get this unit serviced.

Dead appearing ups/inverter


keep on your main switch. off all the lights fan and other electrical items, let that inverter get charge first
