FYI.. this is old news now but for those that were interested. I had my solar PV system upgraded recently with Sustainabode.

All went well. I have upgraded from 3.7kW worth of panels to 4.9kW running on a SMA 4000TL 4kW inverter. I have 18 panels facing north and 6 panels facing west (no more north facing roof space)

The highest I have generated in a day is 33 units. There's a 3 hour period in the middle of the day when my inverter maxes out.
