Default Re: Inverter or generator?

I'm exploring backup power for home and may soon buy a 1.5Kva unit. It looks like an Amaron inverter with two tubular Amaron 150AH batteries will cost around 36k.

Before I bite the bullet, I'm looking for information on Solar-based inverters as well.

How do these compare to the regular inverters, in terms of cost, capacity and performance? Any input on this matter will be greatly appreciated.

They are quite expensive, much more than the inverter.

Hi Airfoil
Better than this you can get a solar inverter combo unit from Sukam directly and it will be much better in technology and also will also have much better support network. Do see the product range from Sukam which they launched some time back.
The link to their product is :

and

What is the opinion on Su Kam brand with regards to after-sales service ? How is the product fit, finish & quality as compared to say an APC ?

I have been using microtek inverter for about 2 years now and find it working good apart from a couple of problems such as the fuse going off due to loading.

Repairs take place in 2 working days.
So far so good. Not sure about sukam but have heard they too are quite good with their products.

thanks for the feedback, APC it seems doesn't have a fuse but uses a reset button on the CB. Which seems convenient because one doesn't need to fiddle around with the fuse. Does Sukam have this fuse as well ? I was looking at a 2.5 kva model from Sukam because APC really goofed up on the service ever since they change the local service provider. So looking out for model which has some local backup and service. How is the Sukam fusion series. Does anybody have experience with this model.

4 hours power cut is driving me crazy. Decided to go for a Inverter. Need to suffice 2 tube lights, 2 fans, modem, wifi router. Which brand, KVA, type of battery. It would be much helpful, if I get the dealer details in Hyderabad/Secunderabad too.

My two bits.
I have been living in a rented house and the owner has already got a Microtek UPS (or is that an inverter?) supported by a 100 AH battery.
http://microtekdirect.com/upse2_625va.php
This is sufficient for our requirement. We don't have too many power cuts out here. The inverter/ UPS can power a couple of lights and fans for a few hours (at least). We never used it beyond that limit since the need was never felt. I don't know why others need 5-7 KVA, but perhaps they face bigger power cuts.

The service from the Microtek franchise is OK. We need to follow up several times before someone comes up to top up distilled water which is needed every 3-4 months.
The last time the guy came, he spilled water all over the place on the battery.
The charge for a fill up is Rs. 200-300 (depending on your negotiation skills).

Once the UPS stopped working and we got the part replacement within warranty.
A few months ago the UPS did not switch over to the mains power even after it returned back. This happened a few times. The technician could not find any fault as such.

The bad part about this setup is the fans make a lot of noise while on UPS mode. I also suspect that the fans are getting damaged due to the low quality output from the UPS, since all our fans have started making noise over the last 6-8 months. The tubelights also make a humming/ buzzing noise, but that is livable.

What is the experience of others with respect to the fan/ light noise?

Now, I have to shift our residence and may need to buy a similar unit at the new place which does not have an inverter.
What is the budget I need for an equivalent setup? I am guessing 10-12K should be enough. This time, I will try something other than Microtek.

I have both an inverter (Sumak 1400VA with Amaron 180AH batteries) and an Usha DG Set (7.5kVA). Of late we seldom require the DG set. We may curse but Kanpur power has improved. The DG is used specifically for the Tubewell and some minor Kitchen work when there is no power and the job has to be done.

I find the Inverter vary good but do have a small issue. While my earlier Luminous had a MCB the current one has a fuse. So replacing a fuse is more painful than just switching On the MCB, after fixing the source of the tripping.

I suspect the noise is coz of the type of your inverter. You would be using a square wave inverter. We have a sine wave inverter and we have not experienced any of these issues.

I would suggest you to go for a pure sine wave inverter at your new place. We have been using sukam smiley 1400VA for almost 6+ years without any issues.

I have a trapezoidal wave form type inverter. I have heard that sine wave inverters are not efficient and expensive too.

That information was from years before...now you wont find much square wave inverter in the market. They are efficient, everyone have changed to sine wave. Ya they are a little bit costly than their counterpart.

Please provide some model numbers and pricing information in the 650 VA range.
