    Peak output exceeding quoted panel output?

    Hi - I have a 2.99kW solar array, and the top output I have had had previously been yesterday's 2800w at one point at lunchtime which I was more than pleased with as I was under the impression the maximum could be 2999w? Today on 3 occasions output was over 3000w (peak was 3080w). Have I got the...

    4000TL: no output

    I noticed yesterday that my SMA 4000TL spent 30 or so minutes producing 0 Watts. There are two arrays on the system and when I checked the inverter display it was showing one of them at 305V between the panels and the inverter and 245V between inverter and the grid. The red light was also on on...

    peak real-world output of Power One Aurora PVI-3.6-OUTD-UK

    My PV system (4kWp of panels with a Power One Aurora PVI-3.6-OUTD-UK inverter) seems to regularly peak at 3608-3610 W. In reading the literature on the inverter I was expecting to see a peak output of 16A which is 3680 watts at 230 volts or 3840 watts at 240 volts. Grid voltage as seen by the...
