Hansol Technics AIO Battery System: Don’t Call It A Samsung

Samsung has decided to let their partner, Hansol Technics, take over their residential battery storage systems. However, the rebranding probably wasn’t done by someone cosplaying as Bob Ross.

There are now over 200 Samsung AIO battery systems installed in Australia, providing battery power to households both on-grid and off.  Their manufacturer, Samsung, is a giant, South Korean based, multinational conglomerate and if you’d like snag yourself a brand new AIO battery system from them, that’s terribly unfortunate, because you can’t have one.

The Electric Car Revolution Is Coming And Cannot Be Stopped

Electric cars are approaching a major milestone.  Soon they will reach 1% of total world vehicle production.

If you don’t think that’s a big deal, consider how quickly things changed once 1% of people had the internet or 1% had smartphones.  This might not seem like a reasonable comparison, as a brand new electric car costs more than twice as much as the latest iPhone, but things are definitely taking off.

Peer Reviewed Study: Grid Connect Solar Helps Environment But Batteries Harm It

academic in ivory tower

A paper published in ‘Nature’ has agreed with Ronald’s back of an envelope conclusions from last year: at the moment, most grid connected storage harms the environment.

Almost a year ago I wrote an article about how on-grid home battery storage does not help the environment but instead harms it by increasing greenhouse gas emissions and other types of pollution. I am raising this topic again, hoisting it above my head, and waving it around, because a scientific paper published in the journal Nature vindicates my position. [Read more…]

Channel 9’s Battery BS

9 news and batteries

SimpliPhi Battery Review: Highly Reliable Storage From The USA

It is currently popular for all the cool kids to be down on the chances of the United States remaining a driving force in world history.  People are saying it has lost its way and only faces turmoil now Batman has passed away and Seinfeld has refused to hug Kesha.

But I have faith in the land that gave us Jim Henson and Ben & Jerry’s Chunky Monkey ice cream.  I think America still has plenty to offer the world.  Sure, maybe nothing as good as Muppets and Chunky Monkey, but still some pretty neat stuff. For example, SimpliPhi batteries. [Read more…]

Beware of Blended Payback: Solar Pays For Itself But Batteries Don’t Yet.

We are seeing a lot of battery companies only quoting the payback of solar and batteries combined. But adding batteries makes payback worse. So always compare the payback of just solar.

Does Rooftop Solar Hurt The Have Nots?

Do solar rebates result in the poor subsidising the rich?

If you spend a significant amount of time on the internet, which I can’t recommend as it is a silly place, then you may have come across people who claim rooftop solar is an enormous scam that depends on government subsidies unfairly taken from those who can’t install it, or choose not to.

Australian battery company DCS are making wild claims about their battery.

Power is boring.

But the struggle to obtain it?  That is interesting.

In 10 year’s time powering homes with batteries may be so commonplace it will be boring.

But at the moment it’s not so dull. [Read more…]

Is it reasonable to expect a “8-15% return on investment” on a Powerwall 2?

Last month, Lyndon Rive, Tesla’s Vice President for Energy Products, stood up in front of a large group of people, including me, and promised the Powerwall 2 will deliver a return between 8% and 15%. [Read more…]
