3 fans for 15 hours but after that light came back didn't notice the maximum backup time. liquid battery need proper maintenance . in dry battery, brand of battery and manufacturing date does matter

on what load ??
i sm talking about durability that dry battery has long life as compared liquid cell battery

[capricon2]

i mtalking about used dry batteries manufacturing date end of 2010 imported from france

[Maaru]

but i have bought this osaka battery now cant replace it.

When I went to buy a ups for my other home I was also thinking of buying homage hax-1002 but the seller told me that this model has been giving complains, so I bought NS! And its working perfectly!

NS stands for? ya ye he pura naam hai ups ka?

I am not really sure. It's easy to calculate though- All you need to know is how many Watts there is in an unit of electricity and how much Gree 1.5 Ton ac consumes in an hour. Then you start adding the numbers up

Sir you are right but the latest ACs like gree since consume less power due to variable speed compressor (as i have heard) prove to be more efficient compared to the usual ACs in which compressor runs on full speed. That's the reason, i am trying to estimate the consumption by a gree AC in a typical month based on the per day operation.

@ capsat sb.; sir any input from your end. Thanks.. Gree / Mr. Slim/ Mr. Elephant (Daikool!)

High-Frequency Chargers

The input mains voltage is rectified and then converted into a high operating frequency (50kHz) by a high-frequency chopping circuit. This high-frequency input is then passed through a transformer and rectified to the correct DC voltage with only a negligible ripple. Because of this high frequency, the transformation can be done with a small ferrite transformer. This makes HF chargers suitable for all types of lead acid batteries.

so this is the entire advantage then....
a smaller transformer is needed.

No need to call me sir, I am probably much younger than you are:)
And, my Gree AC is 8 years old. For the exact specs of new AC's, you would have to take a look at Gree's website:P

Any brother using Gree new AC, please detail about the results.

The only problem with these UPSes is that their charging rate is fixed. Homage introduced Hi-Low charging speeds of 10&20amps but the difference is too big.

Formula of battery charging speed is total battery amperes/10
the osaka battery you have bought has 135 written on it but its actual amperage might be mere 110, 105amps hence you need 10.5 or 11 amp charging speed.

Now 10 ampere speed is too low for the kind of load shedding we face here... but 20amps speed would be too high!

In locql UPSes, which are now available with all kind of goodies the charging rate is adjustable by just turning a screw on the chip.. you can set 15amps in summers to help ur batteries coupe with extreme loadahedding and set it back to 10 during winters.

bdw.. if u want an inverter than try cyberpower.. its a better built than homage

Bought two Gree inverter type AC , one is 1.5 ton and other is 1ton, but the sad part is they are still laying around , could not get time to install . but from operating cost point of view they are cheaper on pocket if and only if you provide electricity contentiously,

[omar4494]

Another plus is as they require less Amp in start up so can easily run on generator , more these units use R410 type gas which has the ability to cool down the temp much faster than R22.

so availability issue....?

wait, R410 is the car AC gas right?

[omar4494]

No! as per my information car AC gas is R134,
Availability of R410 is not an issue, although its bit costly than R22 but easily be sourced in major cities, and as the more local companies are introducing products with R410, i think in next year the price difference of R22 and R410 will disappear, any way a professional can put more insight view about it.
Google the difference of R410 and R22, you will get lots of articles.

Please share the operating results with bill savings.. Thanks

[Farhansa]

You should buy homage.
Peace of mind.

[harib4u]

this one is 1002 660 watt n 1202 is 800 watt n price diff is 500-1000, go for 1202

[heater123]

Please tell me the specs of your solar panel and how many panel. Then i would be able to suggest you type of charge controller

[heater123]

Thin film panels actually need more mounting rails , wires etc and take longer to install; adding to the overall cost of the system, Output efficiency of Thin films are 33% less then crystalline modules so 1.33 KW will equals to 1 KW of crystalline panels, so all the cost you saved on buying thin film will be equals to crystalline because the price difference is almost 15-20 % per watt
