Details :
Now my sukam inverter has two modes UPS mode and W-UPS Mode ( Wide UPS mode)
UPS mode output range - 185V ~270V ( as one can see very narrow operating voltage)
W-UPS mode Output range - 115V ~295V ( Wide operating voltage- Good if power in your area, like my area, fluctuates )
UPS Mode:
If I keep inverter in UPS mode, PC will not reboot when inverter goes into back up mode.
but if I keep inverter in W- UPS mode - Pc reboots in back up mode.
So naturally I will want to keep inverter in UPS mode so that PC does not reboot during back up right?
But the disadvantage of UPS mode is that as soon as supply voltage falls below 185 , it goes into back up mode , so in spite of their being power , but low voltage , inverter will be in back up mode and drain the battery. During this time there will be no charging , so battery will drain soon.
So voltage dropping below 185 is like power failure for inverter in this mode, hence battery is not getting sufficiently charged and I will get less back up, although PC does not reboot in this mode.
W-UPS mode-
Battery charges fabulously as in this mode the Range is wide 115~295, so even if voltage drops below 185 or 140, inverter is still on mains and does not go into back up mode , battery gets charged well, but when inverter is in this mode and there is power failure , then PC will reboot. As there is slight delay in back up in this mode, ( although I cannot understand why manufactures cannot overcome this disadvantage of this Mode)
So what mode do I keep the Inverter in especially when the supply voltage , most of the time is falling below 185V in my region, causing inverter to go into back up when in UPS mode?
if I keep in UPS mode battery Drains and if I keep in W-UPS mode, PC will reboot in case there is a power failure in this mode. I cannot control the Supply voltage to be over 185V all the time can I? so that I can get the Best of Both Modes.
My Intention:
Connect a Small Computer UPS (online interactive UPS), the ones that are small and come with every computer, the ones that provide 15 to 20 min backup.( Cost Rs.2000 - 3000 )
These provide instant switch over, no rebooting takes place.
So Power supply -> Inverter -> Small Computer UPS -> PC
I intend to connect this computer UPS to the output of my inverter, and keep my inverter in w- Ups mode,
so now in w-UPS mode, even if the voltage falls below 185 or 140 my inverter will not go into back up mode, and when there is power failure, the small computer UPS will instantly switch over to back up and prevent my PC from Rebooting,a few seconds later , my inverter will start supplying power to my Small computer UPS and my small computer UPS will dis- engage from Battery mode. So no rebooting even in w-UPS mode.
So for the small Computer UPS, it will be like power has come back on.
so I will have the best of both the Mode, No Rebooting and No going into backup mode when low voltage comes, so good charging.
The only problem; When output of Inverter is connected to Small Computer UPS there is this tick tick noise from the small UPS.
Some say small UPS voltage sensitivity needs to be adjusted, because this clicking sound is from Relay of small UPS.
I really don't know how to solve this.
Inverter is pure sine wave , the out put of inverter is like the output of supply voltage( According to Manufacturer) ,Yet when the Small UPS is connected Directly to the supply there is no Tick tick noise but when connected to inverter there is this Tick tick noise , so what do you people think?
Why is the small UPS behaving differently with inverter? Inverter power = Supply power, as both are pure sine wave.Or is there a defect in the inverter ,maybe it is not able to produce pure sine wave so Small UPS is having difficulty .
My Small UPS model : Microtek HGE600AZ
Inverter Model: Sukam Shiny Series 850VA( Pure Sine wave )
Please suggest, thank you.
