    Dear Welcome all!!

    My question is that is Transformer used in Inverters or not???

    And Second is that:

    In an array of Solar Panels their voltages and power are added or multiplied???

    Regards,

    Muhammad Haris

    Some do, some don't.

    neither (sort of).

    If connected in series, you will get the sum of the voltage at a current equal to the lowest of the panels. If the panels are all alike then multiply voltage by number of panels and use the same current as one panel.

    If in parallel, then you will get the voltage of the highest voltage panel(s) at a current equal to the sum of those that can produce that voltage -- more current will be available at lower voltages. If they are all the same, sum the currents and use the rated voltage.

    Practically, there are other considerations. The rated voltage and current for a particular panel is not what you'll actually get since the voltage is the open circuit voltage and the current is the short circuit current.

    For best performance you typically make your life easier by using the same type of panel (since the array will tend to perform only as well as the worst panel) and use some sort of maximum power point tracking.
