Can this is used with 12v 850va power inverter.

No you need to buy 150 watt 12 volt panel for the same. To calculate the energy it can supply the battery with divide the watts by the voltage of the solar panel. The fact is that solar panels are passive energy gatherers and we can t tell much just looking at or touching them. I would like to have about 300ah of 12v battery 6x2vx300ah flodded units.

With a total of 1200 watts capacity they make 12 volt batteries in the same form factor too but hold less amp hours like around 100 ah but still with a total capacity of 1200 watts since they are higher voltage eg. Overall if everything is on it will be drawing about 240w 20 amps but most of the time i will be using 100w or less and for 2 3 hours per day on average.
