An addendum to a posting a couple of months ago.
The installation is 15 x 270 watt Canadian Tier 1 solar panels each connected to Enphase S-Series microinverters and then to an Enphase Envoy S-Metered 'gateway'. The Enphase Envoy is accessed through the Enphase MyEnlighten app in my iPad. The Envoy feeds into the internet via the wifi here, with the performance of the individual panels able to be monitored worldwide.
Though it took a couple of months to get it working properly, the final link in my ability to monitor performance was completed last week when the Jemena smart meter began to show both consumption and feed-in when the meter is accessed on-line.
During the period the system has been operating we have been able to determine the least costly (best) time to use the high load appliances such as dishwasher and washing machine and only use the gas fire to supplement reverse cycle air conditioning, particularly sitting around the 'fire' at night.
The cost savings in reduced gas and electricity from the grid are already apparent.
Summarised, at this stage very satisfied.
