Inverters will generally never output more than their max-rated AC power. During times when the DC input power is too high, the inverter will raise the operating voltage of the modules to pull the array off of its max power point and reduce the DC power. Why a 20% DC/AC ratio results in minimal clipping losses
Calculate the inverter power output. Given: RP (W) = 1000, E = 85%. Inverter power, P i (W) = RP (W) * E / 100 P i (W) = 1000 * 85 / 100 P i (W) = 850W. An inverter with an efficiency of 90% provides an output power of 450 watts (W). Calculate the rated power of the inverter. Given: P i (W) = 450W, E = 90%.
The key driver here is the “clipping loss”: when the DC power feeding an inverter is more than the inverter can handle, the resulting power is “clipped” and lost. We at Folsom Labs have found that many designers are overly conservative when thinking about DC/AC ratios.
Every inverter has a maximum rated power. This is important for two reasons. First, the component ratings of the power electronics in the inverter are often designed with a specific power and voltage range in mind. Second, at the system level, the home’s AC panel (and/or the grid connection point) are designed with a specific max power in mind.
For example, a 6-kW DC array combined with a 5-kW AC rated inverter would have a DC/AC ratio of 1.2 (6 kW / 5 kW = 1.2). The key driver here is the “clipping loss”: when the DC power feeding an inverter is more than the inverter can handle, the resulting power is “clipped” and lost.
Here’s where inverters come in. Inverter power (Pi) refers to the power output provided by an inverter, which converts direct current (DC) from sources such as batteries or solar panels into alternating current (AC) used by most household appliances.
