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…
Battery Owners: Why You Still See Small Energy Imports Despite a Full Battery
New Catch Control: 6 Channels Of Kick Ass Home Energy Management
For years now, Catch Power has offered what I think is the go-to consumption meter for single-phase houses. Now that the six-channel unit has arrived, your three-phase house can enjoy the same benefits.

I’ve seen more than one instance where roof restorers have ruined solar arrays, and it’s a horribly wasteful lesson for people to learn. If you’re thinking of having your roof painted, then make sure it doesn’t go pear-shaped with this simple guide to restoring a roof with solar panels on it.

When Solar Monitoring Fails: How a Simple Oversight Cost Thousands
A year’s consumption data with a solar power system that stopped dead
Flicking through some photographs recently, I was reminded of a very expensive saga where thousands of dollars of electricity would have been saved with some free solar monitoring. Read on as we detail episode one of several expensive mistakes.
17 Key Insights from Tesla’s Powerwall 3 Training
Tesla’s Powerwall 3 is starting to hit the ground in Australia. We’ve had the launch. Selected retailers are humble bragging about their latest Tesla deliveries hitting the ground, and Tesla is running installer training to get everybody ready. I went along on Friday to see what we could glean.
Your EV Has A 12 Volt Battery – It Can Stop You Dead
Some standards live forever. That’s a 100-year-old battery charger with a glowing valve rectifier maintaining an EV.
Running late on the morning school run? That’s when problems tend to hit. Even with two EVs and a PHEV in the driveway, I’ve learned flat 12v batteries are still a problem, and keeping a few tools handy can save the day.
