Modern inverters connect to Wi-Fi and the cloud — convenient, but a target. Run through this smart inverter security checklist to keep your solar system yours.
Smart Inverter Security Checklist
1. Change every default password. Inverter admin panel, monitoring app, and router — all unique, 12+ characters.
2. Update firmware. Makers like Growatt patch vulnerabilities regularly; check twice a year.
3. Harden Wi-Fi. WPA2/WPA3 only, guest network for the inverter, WPS off.
4. Review remote access. Disable cloud access you never use; keep a log of who has installer access.
5. Enable app alerts. Login notifications and production-drop alarms catch tampering early.
6. Lock the physical unit. A locked, ventilated enclosure beats any firewall against local tampering.
7. Audit yearly. Re-check passwords, firmware, connected devices and app permissions every 12 months.
Why It Matters for Solar Owners
A hijacked inverter can be shut down remotely or misconfigured to damage batteries. Ten minutes of hardening prevents it. Pair security with reliable hardware from our inverter range and the sizing advice in our solar guide.
