As everyone will be aware, Cyclone Alfred is bearing down on some pretty populated parts of Queensland and New South Wales. Solar installers have been posting useful links, so without adding to the information overload we’d like to put a few of the best tips we’ve found together.

Last weekend, I found myself at a gig in Adelaide watching “The Smythes” – a tribute band to The Smiths. As I stood there with my Coopers enjoying “There Is A Light That Never Goes Out”, I thought of the blackout protection I enjoy thanks to my Powerwall 2.

Update 24th Feb 2025:  I mistakenly wrote that the Globird Zerohero VPP allows a household to use up to 0.3kWh of grid electricity during the two hour Zerohero peak and still receive a $1 credit.  But the actual figure GloBird gives is 0.03kWh per hour.  This makes for a total of 0.06kWh over the two hour period.  This figure is low and has the potential to make it difficult for battery households to claim the $1 credit because it’s normal for battery households to still draw a small amount of power from the grid even if they never exceed their battery’s continuous power output.  I called GloBird but wasn’t able to talk to anyone who knew details about the VPP.  I have sent them an email and, hopefully, they will respond to it.  Until I get clarification from Glowbird, I can’t recommend using their Zerohero VPP as it may be difficult for households to take advantage of one of its major benefits.

Update 3rd March 2025:  GloBird have responded and said, for the batteries they have tested, households are able to get through the two hour Zerohero evening peak without exceeding the 0.03kWh per hour grid electricity consumption limit, so are able to receive the $1 credit.   They also sent some bill information on four households showing this.  However, this information was all from summer when small amounts of solar generation during the peak period could have helped the households avoid the 0.03kWh per hour limit.  Until we receive information showing homes can receive the $1 Zerohero credit outside of summer, I recommend assuming you won’t get it any time your solar system isn’t producing a small amount of energy during the second half of the Zerohero evening peak.  I have placed the bill information at the end of the post.

I’ve looked into the pros and cons of a range of Virtual Power Plants, and so far, I haven’t been impressed.  But GloBird Energy’s Zerohero VPP stands out as the best of a bad bunch.  Rather than providing inadequately meagre payments — so long as you have a suitable battery and electricity consumption patterns — its payments have the potential to be adequately meagre.

The only thing that’s grown more than electricity bills recently is the number of new solar power systems installed with batteries. I’m guessing a close third is the growth of my inbox, specifically with questions about small unwanted energy imports. Read on while I explain; please, stop emailing me…

While it’s not a hard and fast rule, my advice for home battery owners who are moving house is this: once they’re installed, batteries are better value staying put. While batteries are expensive, moving them is doubly so. [Read more…]
