cleaner energy automatically
Shîfter is Decent Energy’s smart optimisation product for homes with solar and battery systems. It works alongside your tariff to make household energy decisions automatically, balancing cost and carbon, without extra hardware or effort.
Got solar and/or a battery
but your bills are still high?
Installing solar panels and/or a battery feels like it should automatically lower your energy bills. For many homeowners, that doesn’t happen to the degree they'd expect. Most solar and battery systems are passive. They store energy, but they don’t make decisions about when to use it based on changing prices or the carbon intensity of the grid. Even on smart tariffs, many homes still rely on grid electricity at times when it’s more carbon-intensive or more expensive than it needs to be. If you’ve ever wondered why your system isn’t delivering the savings you expected, you’re not alone.
Having solar and/or a battery is step one. Shîfter is step two: making sure day-to-day energy decisions are being made for your home.
A typical day
Solar generation vs. grid prices
Peak prices hit later in the day — exactly when your battery needs to kick in, but most systems aren't smart enough to plan for it.
What is Shifter?
Shîfter is the product built by Decent Energy to help homeowners get more from their solar and battery systems.
It sits on top of your existing setup and works with your energy tariff, automatically deciding when to store and use energy based on prices and how clean the electricity on the grid is.
You don’t need to manage schedules, watch prices or understand energy markets. Shîfter does this in the background, so decisions are made automatically without requiring ongoing input from the homeowner.
Meet your Power Hour
Every day, there’s an hour when electricity on the grid is at its cleanest.
That’s the least carbon-intensive time to use electricity in your home.
Shîfter identifies this automatically. We call it your Power Hour.
Power Hour is a simple, carbon-led signal that highlights the least carbon-intensive hour to use grid electricity. Shîfter continues to optimise energy use across the rest of the day, independently of Power Hour.

What you’ll gain with Shifter
Save money automatically
Shîfter continuously makes charge and discharge decisions throughout the day, reducing how much higher-cost electricity you buy from the grid over time.
Use cleaner energy more often
By shifting energy use into cleaner periods across the day, Shîfter helps reduce the carbon impact of household energy use.
Works with what you already own
No new hardware or installations. Shîfter connects to your existing system.
No effort required
No settings to manage. No schedules to update. Optimisation happens in the background.
Why homeowners trust Shifter
Many users see meaningful reductions over time, depending on system setup, tariff and usage patterns.
Shîfter only wins when the household wins, because value is tied directly to outcomes, not selling energy or hardware
Works with a growing range of inverters and batteries
Optimisation improves over time as the system learns
