[QUOTE="binky, post: 389445, member: 490"] following on from the Schuco saga, we also fitted a Schuco inverter for the clients parents, 2.85kWp using Schott Panels. This inverter has also failed, and been replaced with an SMA 3000TL. This system is also overunning at 3.0 kW for a couple hours per day on good sunny day. Incidentally Schuco are Kaco inverters re-badged, the rust being down to a decorative trim Schuco fit which is suppossed to be stainless steel, but clearly is a very proor grade if it is! Part of the argument for fitting smaller inverters is the winter performance ie it's suppossed to be more efficient when the panels aren't working at full tilt, hence we fit 4kW of panels on a 3.6kW inverter aswell. Unfortunately we are going to have to wait for winter to resolve that argument now, but I am increasingly of the opinion that the C&G course teachings is wrong. Even if the winter argument is correct, ultimately for a system to pay for itself summer is when the most FiT is generated and that's what makes the system viable investments. [/QUOTE]
