Is it a good deal? Can I negotiate further? (Remember my budget was Rs.15500/-).

In Delhi the 800VA inverter is about 2K. So the rest goes for the battery. Find the cost of battery from an independent source. I doubt you will get a 150AH tubular battery for less than 14K. As summer is coming to an end the demand for inverters is coming down, so you can negotiate like hell, as there may be unsold stock with the dealer!

800VA Sinewave inv is quoted at 5.5K.
Are you sure about the price - 2k? Which brand?

Are you sure it is sine wave. Even local sinewave cost 4500/-

Luminous 800 va cost about 5500 to 6500, so the rest 10000 for a 150 ah battery is not a good deal, buy a branded battery

Last year I paid 12K for Luminous 800VA Inverter consisting of
- Inverter
- Trolley (Steel body on wheels)
- 150AH Exide inverter battery.

The battery was 9K. The original asking price was 15K, but as the dealer was a friend of by brother in law and after negotiating hard he came down to 12k. He told me that the Inverter is "dirt cheap" especially when you factor in the offers dealers get for achieving targets, and he is a very large dealer. The rest was the cost of the trolley and two service visits for the battery. So if you negotiate well, especially at the end of summer; when the sales are dwindling; you can get a very good price.

Note.

No this is not the "Sine Wave", that was 1K more. I tested the output, as our load is less than 300VA on inverter it delivers sine wave. It is only at higher output > 350VA that the waveform starts getting distorted.

The reason for not going for pure sine was primarily the backup time. The modified sine wave inverters give the highest efficiency and for modern fans and lighting, partially distorted wave form does not affect their operation and.or life span. (most of the fan regulators distort the wave form anyway). By the way, the 800VA inverter can run the whirlpool 200L fridge, though now we have it off the inverter to increase backup time.

Any idea about a brand called Southern?

And can't I get 120Ah tubular for 9XXX INR?

[Chipz]

Southern is a good brand in kerala. Check how much guarantee you are getting. Also if any of the dealers is your friend, it would be good to buy from them. Amco semitubular one model has a guarantee of 3 years for the price of about 10000, it might be good too

Aroy; you have got a semitubular battery, which cost around 9000 last year. but the tubular batteries are costly now.

You said you got sine wave in modified square wave inverter?? Square wave is good, but todays LCD tvs have problem with the square wave.

I have run both the 23" TV/Monitor and 50" LED TV on this inverter. There was absolutely no problem. By the way the waveform is not square wave but truncated sine wave, same as delivered by most of the fan regulators. The lower the power drawn the better the waveform.

Also remember the batteries are rated at 10 hour discharge, hence I design my requirements to get at least 6 hours and at the most 10 hours from my inverter at 25-30% load. That gives me plenty of reserve for emergencies.

[Chipz]

I said in general. some Lcd tvs are having problem working with square wave inverter. It is better to check the compatibility before buying.

Hi Chipz,

Final quote I have got:
Luminous 800VA Sinewave Inverter = Rs.5500/-
Luminous 150AH Full-Tubular Battery (18months replacement warranty) = Rs.9500/-
Trolley = Rs.1000/-

Total = Rs.16000/-

Installation = Free; Wiring material = Actuals.

For 4yrs warranty battery he's quoting 1500 rs extra.

[Chipz]

I am not sure of the quality of the tubular battery you are getting since it has only 18 months warranty.

So it is good to give 1500 extra for 2 years additional warranty. Peace of mind for 4 years.

Is he giving 2 years replacement and 2 years service guarantee ?

Nope. Only 18months replacement warranty. Nothing else.

My budget is stirctly 15.5k since it's reimbursed by my company and that's the limit.
I am trying to negotiate for 15k from his quoted 16k.

[Chipz]

I dont think the 18 month warranty battery is good. If it is your company's money, why dont you go for a 120 ah battery with 4 year warranty.

My inverter guy says the battery is Amco 120T and I have 4 year warranty. Is that Tubular? And the price seems ok?

[Chipz]

Ya the 120 "T" is tubular. If it is "F" it is flat plate (not tubular). Check that while taking delivery.

Amco is good and it comes with 4 years guarantee. Have got some good review regarding that from lots of people.

Many thanks Chipz

Bought Amco Insta Power 120T for 9500Rs. Some pix to show how tall it is! The old battery used to sit inside the cabinet.
