Recently replaced the 4.5 yrs old SF Sonic 150AH battery being used for Inverter at my place. The cost of new battery came to Rs 9K in exchange for the old battery.

On similar lines, got a Microtek Inverter USPEB 900 and SF Sonic battery 150AH recently installed at my parents place for a total cost of Rs 16.5K. The Inverter and the battery come with 2 yrs warranty, no pro rata and at all.

Don't go for any Shiny-Finy-Falcon-Salmon. They are best suited for 850 va type applications and will begin to fumble when connected to 40 LED/Plasma type load.

For reliable performance, go for Numeric Digital HPH HR series of heavy duty inverters

OR

APC (any make)

OR

If you are insistent on Sukam, then go for fusion series. 2.2 KVA or 3.5 KVA.

these are reliable models in Indian market at moment.

Kindly excuse if this might not be the right thread. I'm looking for purchasing a clamp type digital multi-meter that could measure a minimum of 100A, both AC/DC. Can anyone recommend me a good and a safe one?

[khoj]

The answer is in your post itself, no? Shiny being sine wave (read squared sine wave) & Falcon being "Pure" sine wave.

Sukam does have childish names for their products but the quality is quite mature.

I have been using a 'Smily' pure sine wave 1400 VA inverter for nearly 6 years now. Have a couple of panels connected & running without any issues.

But all the sellers put Shiny as Pure sine wave. I checked many sellers online and offline.

Could anyone throw some 'light' on this ?

As far as I know, most of the Clamp Type meters are AC only. The only DC ones are based on Hall Effect and are quite expensive (used those with Oscilloscopes a long time ago)

Can you recommend me a good one?

I use a Fluke 374 AC/DC clamp meter along with Fluke DVMs. Fluke makes some of the best measuring devices & test equipment. AC/DC clamp meters are more expensive. But you might as well get an AC/DC model to measure both types of current flow.

I recently replaced inverter at my home with an Exide 850VA inverter with Exide 150 AH Invamaster IM10000 Tubular battery . Total cost minus the old battery is 17200/-.
Why i am quoting a 5year old post is that the replaced battery was of a local Trivandrum make -JAS- 100 AH - Purchased in Aug 2006 I replaced unwillingly because the back up became very poor. I was also filling distilled water religiously every 3 months.
Now seeing the above post and having replaced with a branded Exide battery, I am keeping my fingers crossed!

Been using Exide for several years in cars (decades) and for the inverter since 2010.

While the quality of car batteries has dipped a bit and I have now shifted to Amaron as a trial, luckily the far more expensive 2 x 200AH tubular batteries run well without any issues.

Just keep the distilled water topped up. Check every 2-3 months especially during hot weather and when there are frequent blackouts. Also make sure your inverter's charge voltage and amps are according to recommendations. Normally bulk charging current is at approx. 5-10% of capacity in AH. Float voltage is about 13.8-14.4V (+/- 0.2 V). Read the warranty booklet that comes with the battery. Charging specs are normally specified therein.

If inverter voltages are out of spec get it rectified by the inverter manufacturer. That's critical because the life of the battery depends on the charging voltage/current among other things.

As you can see the AC/DC meter is quite expensive.

That's why I suggested the OP should 'Choose as per your budget'

Fluke instruments are expensive but they are probably the last clamp or DV meters you would need to buy for a very long time.

There are less expensive Indian and Chinese brands like Mastech, Meco, Sanwa etc. But when it comes to electricity I prefer not to take risks and buy a product that's built to international safety standards.

Gentlemen,

I need to get an inverter for running 1 tube light (36W) 2 all out mosquito repellant machines ( 2 *10 watts i think ) 2 medium size Ceiling fans ( 50*2 watts i think ) for around 5-6 hours backup ( max ).

I will have to place the inverter in the living room ( no other place available ) where a very active toddler keeps playing. So i have no choice but to get SMF batteries.

I was initially thinking of

a) Exide it500GEL with a exide 850 va inverter.

But the exide bettery spec sheet mentions its weight as 60KG.
This will make the battery unwieldy to handle.

So instead i am thing of

b) Two 65ah AMARON Quanta batteries with a 850 SU-Kam inverter. I will connect the two batteries in parallel. Each battery is 20 kg so will be much easier to lug around if the need arises.

What say ?

[Aroy]

Just take into account the capacity calculations.
. The capacity in AH is for 10 or 20 hours discharge. For shorter duration you have to derate accordingly.
. The rated capacity is generally at 25 degrees centigrade. At 40 degrees the capacity will be at the most 60%.
. The inverter efficiency is between 80-90%, take that into account.

So in general for Indian Summer conditions and 5 hour capacity, the capacity in AH will be at least 2 times that calculated based on load.

If your requirement is 2xfans + 2xlights(CFL/LED), the total load will be around 150W. For 5 hours that gives 750W-H, with derating 1500W-H. with 12V battery that is around 120AH.

The battery electrolyte indicator stalk broke. Can i use 5 rupee Anabond/fewi qwik to fix it?

Will the dried adhesive react in/with the electrolyte?

Don't. Better buy a new one from a battery shop - doesn't cost much. Sticking it back might contaminate the electrolyte and reduce life of that cell.
