Available Energy at Inverter Output

What this step does

The AC energy at the inverter output after every inverter loss and the night consumption, summed over the inverters.

The math

$$E_{inv} = E_{mpp} + \sum_k \Delta E_k \tag{1}$$

where

Symbol	Meaning	Unit
$E_{inv}$	the energy at the inverter output	kWh/kWp
$E_{mpp}$	the array energy at maximum power	kWh/kWp
$\Delta E_k$	the inverter rows between the two, losses negative	kWh/kWp

Reading the number

A total, positive: usually 94 to 98 % of the array energy at maximum power, on utility and rooftop systems alike. A high DC-to-AC ratio and string voltages outside the inverter's MPPT window lower it.
