We need an inverter of 75 kwatt power for our mini grid. Do we get inverter of such a large size? Or we have to connect tw0 or more inverters in parallel. How can we connect inverters in parallel.

    There are a number of inverters designed for parallel operation. I run a pair of Outbacks in a parallel config.

    At 75kw, you should probably be talking to the likes of Schnieder for a properly engineered solution though - not really a DIY IMHO.
    Off-grid.
