Is over-allocation allowed for PV inverters
Global electrical codes provide clear guidelines for safe over-allocation: "Proper over-allocation can boost annual energy yield by 8-15% without compromising system longevity," says a 2023 IEEE report on solar optimization. A German commercial installation using EK SOLAR. . PV inverter over-allocation refers to connecting a photovoltaic (PV) array with a higher DC capacity than the inverter's rated AC power output. For example, pairing a 12 kW solar array with a 10 kW inverter represents a 20% over-allocation ratio. Such as a string inverter, its AC side rated power parameters is 36kW, but according to its DC side of the real maximum power can be configured to the power of only 34KWp, taking into. . The potential capacity of the inverter can be fully tapped through over-allocation design (i. Designers often talk about a. .Read More Download PDF
