    Hello Sir
    Previously I used WEP inverter which was producing sine wave output. It got failed recently. I want to purchase a new one. As you mentioned in the above article, I want to go for a inverter which should have LCD display, voltage stabiliser, ELCB and other latest technologies.

    Kindly suggest me a new branded inverter.

    And also tell me about the inverter which supports the solar technology. This will help me to upgrade solar technology in future.
