The DC high voltage before the inverter is lower than the AC
A 48V battery-based inverter typically boosts the DC voltage internally before inversion you're going from 48V to maybe 350-400V, then inverting to AC. Each conversion step costs you 1-3% efficiency. A high voltage system feeding from a 400V battery or solar string skips. . Over the past decade, PV module prices have decreased roughly ten-fold and nominal operating voltages have increased from 600 VDC to 1,500 VDC. 25 to a range. . DC/AC ratio, also called inverter loading ratio (ILR), is the array's STC power divided by the inverter's AC nameplate power. So each string has to be above this voltage separately or does the whole array work to achieve this startup voltage independent of the amount of strings? I would say 90v for EACH MPPT input, separately. This method is standard practice within imperix power converter systems.
