Growatt Companion

GW Companion lets you monitor and control your Growatt solar inverter directly from your Android phone.

Connect with your Growatt API token and get instant access to:

• Real-time power flow — solar production, grid import/export, battery charge and load
• Energy today — track how much solar you've generated, consumed, exported and stored
• Battery status — state of charge and charge/discharge power
• Alarms — view active and resolved inverter alerts
• Home screen widgets — see your solar data at a glance without opening the app
• Economy overview — estimate savings and earnings based on your electricity price

Supports multiple Growatt inverter types including TLX, MIN, SPH, SPA, Storage and more.

Try all features free for 10 days — no commitment required. After the trial, a subscription unlocks continued access.

If two BDCs are connected, the Growatt server does not provide all parameters for BDC2, BDC1 is fully supported

Your data stays on your device. No account needed beyond your Growatt API token — nothing is shared with the app developer.
