Beating Power Cuts and Energy Prices in the Countryside

When Stuart first reached out to Creative Low Carbon, his goal was simple: find a way to bring down the cost of running his large, all-electric home. Living in a rural location, he also faced another challenge, semi-frequent power cuts that left the whole house vulnerable and cold if for a long period of time.

We designed a system around his needs: a 15kW three-phase SigEnergy inverter, paired with three 9.04kWh batteries and a three-phase SigEnergy HomeMax Gateway. The inverter provides plenty of headroom for his home’s heavy usage, while the HomeMax ensures the entire house stays powered during outages. With the heating & hot water handled by an air source heat pump for a fair-sized footprint to look after, Stuart’s energy demand is no small thing.

But the story didn’t stop there. Just a month after his installation, Stuart called us back. He was so impressed with how the system performed that he decided to double down - literally. We added another three 9.04kWh batteries, expanding his storage to a massive 54.24kWh of capacity with a full 15kW charge and discharge rate.

This huge storage capacity pairs perfectly with Stuart’s electricity tariff: Intelligent Octopus Go. Every night, he gets six golden hours of power at just 6.5p/kWh. His batteries fully charge in that window, covering his daily usage. Which means Stuart effectively pays 6.5p/kWh for all his electricity, no matter when he uses it. Even if Stuart is away, or his usage in the summer is lower, the entire battery stack earns it's keen thanks to SigEnergy's innovative AI mode. Performing energy arbitrage to maximise income.

For now, solar panels are on hold due to planning restrictions. But thanks to his hybrid inverter, the system is already future-proof. As soon as permission comes through, solar will be plug-and-play, seamlessly adding free, green generation to his setup.

Stuart’s home is now more resilient, more independent, and far cheaper to run. His system proves that with the right design, even a power-hungry countryside home can stay one step ahead of the grid.
