Invertor for New house

[ramki067]

In order to optimize the battery Ratings and to get long duration back up using UPS Line,

1) Do not use Regular Tube lights. They consume more power(Nearly 50W including the Choke). Instead use CFL lights(you can use 4 Nos of
11W-14W CFL's in place of 1 Tube Lights).

2) Use less number of Fans during back up time, they consumer more power and unwanted usage of all fans will drain out your back up capcity.

3) Always use Sine wave Output UPS Systems. Square wave Inverters may reduce the life of your appliances or may not give the best performance.

Thanks for the insight.
But instead of CFLs, if we use LEDs its even more saves half the cost of electricity bill over CFLs right?
Also the life of LEDs are more compared to CFLs.

Of Couse, you are right.

White LED Lights works on DC Voltage, against UPS system which gives AC Voltage.

So in order to use LED lights, either you need to use DC Voltage from the Batteries bypassing the UPS,
which requires separate wiring or need to use Electronic Ballasts. Moreover the transmission loss is
more for DC voltage in case of lengthy wirings, which also gets added in addition to the self drainage
of the batteries.

Also at present the LED Light Cost is at least 5 time higher than the CFL Lights.

Hi,
You can use LED lights that comes with built in choke (transformer).Now the prices of led lights are just about 2-3 times the cfl ,at the same time life of led is 4-5 times more than cfl.
In general led life is about 50,000 burning hours (life time).

Thanks msn1270 for the insight.
So, if we have to cover 4 tubelights and 4 fans all over the house using UPS, do we have to do a separate wiring from UPS to these lights and fans?

Even though ideally Mfr's claim 50,000 hours as the life time for LED's, practically we don't get it.
Same case for CFL lights also, they claim 10,000 hrs, but it will not last more than 2-3 years, @ 4hrs/day, which gives
around 4000-5000 hrs life Max.

We may get cheaper LED Lights, but not a good quality or branded one. Recently I tried 2 No's of Wipro make
0.5W color Light(similar to the 10W (Zero Candle) Bulb @ Rs. 110/pc, unfortunately, it did not even last for 2 weeks.)

If we go for a known brand like Philips/Osram(Siemens)/...etc, for even a 3W - 4 W LED bulb, the entry level
price is around Rs. 650. Higher wattage & better one goes in the range of 3,000 to Rs. 4,000/- for each bulb.
IMHO, it is still not affordable to the middle class.

I am interested in hybrid UPS\inverters where we can use both solar and regular means to charge the batteries. Due to lack of funds I am planning to install the inverter only in the future with the wiring in place now. What provision should i make from the roof to the place where i plan to place the battery setup if i need to connect a solar collector in the future and make it charge the batteries? Will just a set of wiring from roof to battery enclosure suffice?
