This is the device which converts DC voltage from solar panel to 240 volts AC without requiring any battery basically a inverter. The unique thing is it does not require any battery to run you can connect it directly with solar panels , not like other solar inverter which requires a battery adding the battery means adding the maintenance, this thing will last for years as this has only the circuit and transformer which is not easily gets damage all n all Maximum output you can take from this inverter is 100 watt so you can run appliances which consume less than 100 watts like LCD or LED tv , laptop charging , multiple phones and smartphone charging , table fan , ceiling fan , tube light , cfl , led lights , printer , water filter or any thing which consume less than 100 watts. Note - device will only work with 12 volts panels, not with 24 volts or panels which are connected in series.
