Luminous Inverter and UPS Review

                                Luminous Inverter and UPS Review

This is Alex.Searched a lot with many dealers and distributors for the good backups and finally ended up with a good deal. This is gonna be a genuine review based upon my experience with the product.

I have recently installed the Luminous 875 Sine wave inverter + 150ah Okaya Tubular battery for Rs. 16K including the installation cost. It's really worth the money spent on it.

The battery backup is good and it will make you realize you with the beep sound for 5 times once the power goes off.

Let's start with the Luminous 875 pure sine wave inverter. It costs me around 5k. It consists of the copper winding for better stability while operating and it's better than the silver winding used by the Microtek inverters. The inverter has two switches for battery selection at the back. One is for Tall Tubular battery and another one is obviously for Tubular battery

Modes of Inverters:

Regulated Mode:

I have used the inverter in ups aka regulated mode selected.

The issues faced while in the ups mode is that once the power goes below  i.e, 180 volts, the ups mode get's activated in spite of mains current is available.

This will surely drain the battery and it's advisable to use only if you are using a desktop.

Unregulated Mode:

Now comes the Unregulated mode in the inverter.

If this switch is activated things changes in the inverter.

An audible humming sound in noticed and when the voltage drops to below 120 volts that are where this inverter runs onto ups mode.

This is the most recommended mode for the Indian cities where power fluctuates from below 180 - 250.

The switching time to ups mode is quite similar to the regulated mode. This is the triumph card of this inverter.

Okaya Tubular Batteries:

The smart charging gets activated once the power comes on.

The performance of the batteries is up to the best till now and hope to be the same in coming years.

No of hours backup = (ah of battery * 12 volts) / Load (watts used).

2 Fans - 160 watts + 1 CRT TV - 120 watts + 2 Tube light - 80 watts (Load) = 360 watts

Practical formula = (150*12)/ 360 = 5 hours of back up.

Good one.

Need to add this user-friendly feature. Displaying the backup time available in ups mode.

Happy reading folks.
