Solar monitoring, power diverters, optimisers and battery add-ons help you use more of the electricity your panels produce rather than exporting it cheaply. They're the key to maximising solar self-consumption.
Why solar accessories matter
Every unit of solar you use yourself is worth far more than what you're paid to export. Diverters and monitoring shift usage to sunny hours and squeeze more value from an existing solar system.
