Types of Inverters. There are several types of inverters that might be installed as part of a solar system. In a large-scale utility plant or mid-scale community solar project, every solar panel might be attached to a single central inverter.String inverters connect a set of panels—a string—to one inverter.That inverter converts the power produced by the entire string to AC.
Installers typically follow one of three common solar inverter sizing ratios: For our example 7 KW system, this translates to inverter sizes between 8,750 watts and 9,450 watts. While the above wattage rules apply to a majority of installations, also consider the following factors before deciding the sizing ratio.
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.
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.
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:
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.
Using three 12.6 kW string inverters in this 30 kW commercial solar PV system allows for modular expansion later. The inverters are perfectly sized at 1.25 times the array’s capacity. Improperly sizing the solar inverter can undermine the purpose of investing in an expensive PV system.

To size an inverter correctly, you need to consider: The Total Capacity of Your Solar Panels The combined wattage of your solar panels (e.g., a 6 kW solar array) is the starting point. Your inverter size should align closely with this value.
Solar inverters are rated according to their maximum output in VA, KVA, or Watts. A 5kw inverter will deliver a maximum of 5000 watts of AC power. Microinverters coupled with a single solar panel have particular solar panel requirements in terms of DC input to the inverter. Calculating the size of the inverter required is straightforward.
However its output can vary depending on how much solar energy is converted. Imagine you have a 7 x 300W solar array and a 2000W load on the inverter. At noon the sun is at its peak and the array produces 2000 watts. But the output will go down eventually. From 290 watts the number will drop to 280, 250, 180 and so on until the sun sets. When computing sun hour availability, …
The size of your solar inverter can be larger or smaller than the DC rating of your solar array, to a certain extent. The array-to-inverter ratio of a solar panel system is the DC rating of your solar array divided by the maximum AC output of your inverter. For example, if your array is 6 kW with a 6000 W inverter, the array-to-inverter ratio is 1.
When sizing an inverter, calculate the total wattage needed and understand surge vs. continuous power. Choose the right size with a 20% safety margin. Factor in simultaneous device use and peak power requirements and add essential margin for future power needs and system upgrades.
A general rule of thumb is that the inverter size should be about 80-100% of the solar panel capacity. For example, if your average daily energy consumption is 20 kWh, and you have 10 solar panels at 300 watts each (totaling 3 kW), then your inverter should be sized between 2.4 and 3 kW. 4.
