"Your family grows. Your energy needs change. Your system should grow with you— adding capacity when you need it, selling surplus when you don't, and adapting to every season of life."
A system that grows with you
Start with 10kWh of storage—enough to power your home through the night and then some. When your family grows, when you add an EV, when your needs change—simply stack another battery. No rewiring. No hassle.
The SIG Energy system doesn't just store power—it thinks. Dual MPPT tracking optimises every panel, even on complex roofs with multiple orientations. The intelligent controller learns your usage patterns and maximises self-consumption.
And when you generate more than you use? Sell it back to the grid. Watch your earnings accumulate. Turn your roof into a genuine income stream.
Intelligence built in
Control your energy like never before
Real-time monitoring
See exactly where your energy comes from and where it goes. Watch your generation climb as the sun rises. Track your savings accumulate hour by hour, day by day. One app. Complete visibility.
Grid export earnings
When your batteries are full and your home is powered, your excess energy flows to the grid—and cash flows to you. See your earnings accumulate. Turn sunshine into a genuine income stream.
Seamless backup
When the grid fails, your home doesn't notice. The switchover happens in 20 milliseconds—faster than a light can flicker. Set your backup reserve, and sleep soundly knowing you're covered.

"We didn't even know there was a power cut until the neighbours mentioned it"
The Williams Family, Sheffield — December 2024
Their EV charged through the night. Their fridge stayed cold. Their heating kept running. The 20-millisecond switchover meant life simply continued—while three streets sat in darkness.
