Determining the size of the inverter you need is determined by a few critical factors:

    Why are solar inverters sized lower than kilowatt peak?

    Inverters are usually sized lower than the kilowatt peak (kWp) of the solar array because solar panels rarely achieve peak power. The solar array-to-inverter ratio is calculated by dividing the direct current (DC) capacity of the solar array by the inverter's maximum alternating current (AC) output.

    How much power does an inverter need?

    Naturally, you'd need to spec the inverter to deliver the maximum power required, even if it is only for a short time, such as when accommodating surges from a motor or fridge compressor starting. Should the home draw, for example, 2500 watts at peak consumption, the inverter should have a continuous power output rating of at least 2500 watts.

    How to choose a solar inverter?

    Choose an inverter that has a surge watt rating equal to or greater than this value. As for voltage drop, check the wire length between your solar panels and the batteries. If the wire length is long, you may need to choose a lower voltage system (12V, 24V, or 48V) to minimize voltage drop.
