Great to see credits coming in through the energy account.

This month saw the first sizable dollar credits  in our power account, albeit that it may have been due to their estimation process. We had a credit of over $65 for the month.

The month also generated for the first time over 300KW's for the month averaging over 10KW each day and peaking at 15.1KW on the 31st October. The next few months leading up to the longest day should give really good results.

The rest of the house is working really well, although we did have an incident part way through the month. We had a planned power outage on one day for 3 hours, but no one told us, and as a result the hot water system that collects heat and heats our hot water and stores heat in our core over heated. The pumps turned off once the Uninterrupted Power Supply (UPS) ran out. The water in the solar panels on the roof then went to over 120 degrees C and turned into steam. Once the power came back on the pumps pushed this steam down into the core and blew two of the six pipes at the ground level in our laundry. Luckily the door to the rest of the house was closed but we ended up with a sauna in the laundry and total loose of pressure. The system survived but still needs to be fixed so that we can run it properly. The redundancy in the piping in the slab and core have taken over and we are collecting heat still but only providing storage to two thirds of the core.

The power company has admitted liability, having failed to notify us of the outage. We are now looking at solutions to ensure that the UPS can survive in the future.
