A 4.5 kW array (or ten 450-watt solar panels) would just about cover your consumption. The type of solar panels you choose can also impact the size of the inverter you need. Different types of solar panels have different wattage ratings and efficiency levels. The three main types of solar panels are monocrystalline, polycrystalline, and thin film.
The need for an inverter size chart first became apparent when researching our DIY solar generator build. Solar generators range in size from small generators for short camping trips to large off-grid power systems for a boat or house. Consequently, inverter sizes vary greatly.
A solar inverter can be undersized in two ways, buying a smaller inverter or increasing the number of existing solar panels. Undersizing the inverter results in more power clipping, meaning that the inverter discards excessive power generated by the solar panels. Determining the size of the inverter you need is determined by a few critical factors:
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.
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.
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.
