I have a vessel with 2 Quattro 8000VA inverter/chargers and two 24V Skylla-i 100 amp standalone chargers. They are located in an air conditioned space. I am unable to get full charge capacity from the Quattros when charging our large battery bank. Each inverter/charger is rated for 200 amps of DC charge output so together they should produce 400 amps. I initially get very close to that but after a few minutes charge production falls off to around 300 amps - a loss of about 25%. The units are installed with the required perimeter clearance around them. My suspicion is that the charge capacity is degrading due to heat. I see no degredation in the charge output of the Skylla chargers. Their charge output is always 99.9 or 200 amps. They too are installed with the required perimter open space clearance and are in very close proximity to the Quattros. I am located in a warm climate and can cool the room where this equipment is installed to a temperature of 70°F. I am suspicious that regardless how cool the environment is where this equipment is located their internal operational temperature will be excessive enough to cause the charge output to diminish. If so, then the rated amperage of 200 amps per unit is misleading and unrealaistic. Is there any publised information as to how specific temperatures might influence the Quattro? If they are heat sensative and there is a sensor that throttles the output does anyone know where it is? I am frustrated that I cannot consitently get the maximum rated output when these are installed in an unusually cool environment for a vessel. I am trying to better understand just how they work.
