The maximum power rating is the amount of DC power that the inverter can accept from the PV array before it starts shutting down in order to protect itself from damage. This value is usually about 20-25% higher than the nominal power rating which refers to the AC power that the inverter can deliver under normal operating conditions.
What is overloading? Overloading is when you install a solar array that has the ability to generate more electricity than your inverter’s maximum output capacity. For example, a system that has an inverter that’s “25 % overloaded ” (or 125% loaded) would mean the DC array size is 25% larger than the AC rating of the inverter.
An on-grid inverter does not have a demand for AC overload, as the inverter output power will not exceed component power. In a solar PV off-grid system, the component, battery, inverter, and load make up the electrical system. The output power of the inverter is determined by the load.
For example, a system that has an inverter that’s “25 % overloaded ” (or 125% loaded) would mean the DC array size is 25% larger than the AC rating of the inverter. Inverters are power electronics devices which give maximum efficiency when input power is close to 90-100% of the inverter’s rated power.
Inverters are usually sized so that they can handle 100% of what the PV array can produce under optimal conditions. Most residential systems have between a 3kW and 10kW inverter. Inverters also have limits on how much DC voltage they can take in, based on design voltages for safety reasons.
Solar inverters are devices that convert the DC power produced by solar panels into AC power that can be used by home appliances. Many people believe that it is better to undersize their solar inverter so that it produces less power than what is needed by the appliances, but this is not always the case.
