DeliosEnergy turns your iPhone and iPad into the dashboard of your solar system powered by a Delios hybrid inverter. The app connects directly to the inverter on your local network โ€” no cloud, no account, no middleman โ€” and shows everything that matters in real time: โ€ข SOLAR PRODUCTION โ€” how much energy your panels are generating right now โ€ข BATTERY โ€” charge percentage, charging/discharging power and estimated time to full charge or empty โ€ข GRID โ€” how much energy you are importing from or exporting to the grid โ€ข HOME โ€” your house's instantaneous consumption โ€ข GREEN ENERGY โ€” the share of consumption covered by sun and battery, so you can see at a glance how self-sufficient you are The energy flow between sun, battery, grid and home is visualized with an animated diagram, in a clean modern interface with full light and dark mode support. 30-SECOND SETUP Enter the inverter's IP address (or hostname), username and password, run a connection test and you're done. Data refreshes automatically. TOTAL PRIVACY DeliosEnergy collects no data whatsoever: the app only talks to your inverter, on your network. Credentials never leave your device. REQUIREMENTS โ€ข Delios hybrid inverter reachable on the local network (same Wi-Fi) โ€ข iOS 16 or later Note: unofficial app. Delios is a trademark of its respective owners; this app is not affiliated with, sponsored or endorsed by the inverter manufacturer.
