Growatt Solar Monitor & Widget

Monitor your Growatt solar inverter in real time — battery charge, solar production, home consumption and charge power always at your fingertips.

WHY THIS APP

The official Growatt app is bloated and ad-supported. TinyGrowattMonitor gives you exactly the data you care about: clean, fast, private. No ads. No subscription. No tracking.

FEATURES

• Real-time solar dashboard — battery state of charge (%), solar power (PPV), home load and charge power; refreshes on demand and automatically every 5 minutes
• Home screen widget — two sizes: compact 3×2 status bars and a 3×3 arc-gauge widget showing battery %, solar, load and charge stats at a glance — no need to open the app
• Battery low alert — configurable push notification when your battery drops below a threshold you choose
• Auto storage device detection — no manual ID entry; the app finds your Growatt storage device automatically after first login
• Offline cache — last known readings always visible, even without internet
• Dark mode — follows your system light/dark theme automatically
• Minimal permissions — internet only; no location, no contacts, no microphone, no camera
