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.
If the solar panels have minor shading issues during certain times of the day, increase the inverter’s capacity to compensate for the reduced energy generation. High outdoor temperatures will lower solar panel efficiency. So for hotter locations, oversize the inverter slightly to account for performance dips.
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.
Derating Factors Derating factors are conditions that can reduce the output of your solar panels, such as high temperatures, shading, or soiling. To account for these factors, you may need to size your inverter slightly larger than the DC rating of your solar array.
Solar inverters are the brains of the operation when it comes to solar systems. The inverter is the central meeting point for the power coming from the solar panels, grid power in and out, battery power in and out, and sometimes a generator port.
Solar panels operate best at between 30-40V for residential and 80V for commercial systems. While there are single-phase and three-phase grid-tied solar inverters available, residential units typically feed to split phase 120/240V panels. Note the voltage specifications when choosing the appropriately sized solar inverter.
