About this app
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
WHO IS IT FOR
Growatt solar inverter owners who want a fast, distraction-free way to check battery status, solar production and home load — without opening the full official app.
Compatible with Growatt inverters accessible via the Growatt OpenAPI. Log in with the same credentials you use on the Growatt website or official ShinePhone app.
HOW IT WORKS
1. Sign in with your existing Growatt account
2. The app automatically detects your storage device — no configuration needed
3. Dashboard and widgets update every 5 minutes in the background
Your credentials are stored locally on your device only and are sent exclusively to the official Growatt API (openapi.growatt.com).
PRIVACY
No ads. No analytics. No crash reporting. No third-party SDKs of any kind. The only permission required is internet access to reach the Growatt API.
