hi, new to this side, i have just got installed 5048D-ES and i have no way to monitor the system, i cannot reigister the inverter on sems it say's the plant is already in use elsewhere, i think the electrician did it but didnt give me the details for it, anyway, this thing Cef has made looks very good, question is does it take up much space on my computer and slow it down? ore is it just an easy running thing, im not good with computers ore anything but will try this, thank's
