We bought an EV – our Zappi does a great job

We said as soon as our local town got an EV charger we would buy an electric car. In September, a charger was installed, so we carried through and bought a car. Our car has two and a half times the battery capacity as our house, so we needed a smart charger – one thatContinue reading “We bought an EV – our Zappi does a great job”

A solar update

So with the installation of the Daikin ducted RCAC, water & sand filter pumps and the Reclaim 315l heat pump hot water we are finally able to draw some reasonable power from the solar system and start testing things. SMA – Sunny Boy/Sunny Island Inverters SMA have been very unimpressive to deal with. In Australia,Continue reading “A solar update”

After quite a bit of fiddling (didn’t get any decent instructions from the installers on start up and shutdown) and some googling manuals, finally managed to fully shut itContinue reading “Solar systems problems – 2 x 50% saves the day”

We wanted to be able to heat the whole house, so wanted something beyond the  wood heater planned for the living room. One of the reasons that we chose our builder was because they had recentlyContinue reading “Heating”

Cooling

Cooling was an easy decision. Installing ducted air conditioning might seem counterintuitive for an off-grid, energy efficient house, but one of the learnings from the shed is that there is a lot of excess energy available in summer. When you do the numbers, it works easily. Depending on our final system sizing, it might notContinue reading “Cooling”
