Solar alone is good. Solar with Sentinel™ is transformative.
Most solar systems reduce bills. Very few are actively optimised. Energy pricing changes daily. Grid opportunities come and go. Systems drift, performance slips. Without active optimisation, you leave money on the table.
Every Sentinel package includes Sentinel Protect as standard. That means real people keeping an eye on your system, spotting issues early and fixing problems before they affect performance.

Sentinel™ is built to support an expanding range of battery and inverter systems, with compatibility continuing to grow as we integrate with more manufacturers. We currently support FoxESS, with further integrations in development. For the latest updates, you can check current compatibility on the official Sentinel™ website. If your system isn’t listed yet, you can still register your interest and we’ll keep you informed as support becomes available.
Different homes need different levels of optimisation. Sentinel offers three clear options, dependent on your energy tariff, system and the level of optimisation you need.
