Bigger battery, bigger savings?
Not necessarily.
It's one of the most common assumptions we walk people through before they commit to anything.
Battery size should match how your household actually uses power, not how big your solar system is. Get that wrong and you're either paying for storage you'll never touch, or still buying grid power on cloudy days.
Here's the bit most people don't know: batteries like the Sigenergy SigenStor is modular. That means we can size it around your actual usage now, and add capacity later if your needs change. We're all about Future Proofing your home.
For these installs, we looked at the customer's export data and usage before landing on the right size.
