I purchased this product 2 years ago, and thats why I am liable to write a detailed review on this product.
I live in a three story building, I have this inverter which is getting power of 2 batteries of the same brand, when we need less power, I turn on the ECO mode and when we need more power in summers, then Inswitch it to UPS mode. All you need to do is to push and hold the power button for 3 seconds, and it will change its mode.
The power consumption is also good. I live in Ghaziabad, and earlier, there was too much of power cuts, so this inverter never disappointed us.
It is of complete copper electronics, which are reliable, and the after sale service is also up to the mark.
Thanks luminious for lighting our house. ??
