No sensor can tell the current direction and the inverter draws 75W in standby. So, whilst Wattson thinks you are producing 75W you are actually using an 150W more than the 'net power' figure on the display. The only 'solution' is to isolate the system at the switch of or the fuse. It saves 10p per night but will cost much more if you forget to turn it back on in the morning. The inverter only works to a certain level and once it switches off (red light on the meter) it draws 140W for a few minutes to cool down before dropping to 75W in 'sleep' mode. Does this help?

Hi. I am using a Wattson to monitor my consumption and PV generation. The meter appears to give an error when the PV output is below a 100W, reads no lower than 140W and when the PV is shutdown 75W. If the 230v AC is isolated the meter reads 0W. Any ideas?

Regards Warren Richards
